Prostate Health: What You Should Know
We’re aware that very many of our readers are women, who do not have a prostate.
However, dear reader: if you do have one, and/or love someone who has one, this is a good thing to know about.
The prostate gland is a (hopefully) walnut-sized gland (it actually looks a bit like a walnut too), that usually sits just under the bladder.

*The scale is not great in these diagrams, but they’ll get the job done. Besides, everyone is different on the inside, anyway. Not in a “special unique snowflake” way, but in a “you’d be surprised how much people’s insides move around” way.
Fun fact: did you ever feel like your intestines are squirming? That’s because they are.
You can’t feel it most of the time due to the paucity of that kind of nervous sensation down there, but the peristaltic motion that they use to move food along them on the inside, also causes them push against the rest of your guts, on the outside of them. This is the exact same way that many snakes move about.
If someone has to perform an operation in that region, sometimes it will be necessary to hang the intestines on a special rack, to keep them in one place for the surgery.
What can go wrong?
There are two very common things that can go wrong with the prostate:
- Benign Prostate Hyperplasia (BPH), otherwise known as an enlarged prostate
- Prostate cancer
For most men, the prostate gland continues to grow with age, which is how the former comes about so frequently.
For everyone, due to the nature of the mathematics involved in cellular mutation and replication, we will eventually get cancer if something else doesn’t kill us first.
- Prostate cancer affects 12% of men overall, and 60% of men aged 60+, with that percentage climbing each year thereafter.
- Prostate cancer can look like BPH in the early stages (and/or, an enlarged prostate can turn cancerous) so it’s important to not shrug off the symptoms of BPH.
How can BPH be avoided/managed?
There are prescription medications that can help reduce the size of the prostate, including testosterone blockers (such as spironolactone and bicalutamide) and 5α-reductase inhibitors, such as finasteride. Each have their pros and cons:
- Testosterone-blockers are the heavy-hitters, and work very well… but have more potential adverse side effects (your body is used to running on testosterone, after all)
- 5α-reductase inhibitors aren’t as powerful, but they block the conversion of free testosterone to dihydrogen testosterone (DHT), and it’s primarily DHT that causes the problems. By blocking the conversion of T to DHT, you may actually end up with higher serum testosterone levels, but fewer ill-effects. Exact results will vary depending on your personal physiology, and what else you are taking, though.
There are also supplements that can help, including saw palmetto and pumpkin seed oil. Here’s a good paper that covers both:
We have recommended saw palmetto before for a variety of uses, including against BPH:
Too much or too little testosterone? This one supplement may fix that
You might want to avoid certain medications that can worsen BPH symptoms (but not actually the size of the prostate itself). They include:
- Antihistamines
- Decongestants
- Non-steroidal anti-inflammatory drugs (NSAIDs)
- Tricyclic antidepressants (most modern antidepressants aren’t this kind; ask your pharmacist/doctor if unsure)
You also might want to reduce/skip:
- Alcohol
- Caffeine
In all the above cases, it’s because of how they affect the bladder, not the prostate, but given their neighborliness, each thing affects the other.
What if it’s cancer? How do I know and what do I do?
The creator of the Prostate Specific Antigen (PSA) test has since decried it as “a profit-driven health disaster” that is “no better than a coin toss”, but it remains the first go-to of many medical services.
However, there’s a newer, much more accurate test, called the Prostate Screening Episwitch (PSE) test, which is 94% accurate, so you might consider asking your healthcare provider whether that’s an option:
The new prostate cancer blood test with 94 per cent accuracy
As for where to go from there, we’re out of space for today, but we previously reviewed a very good book about this, Dr. Patrick Walsh’s Guide to Surviving Prostate Cancer, and we highly recommend it—it could easily be a literal lifesaver.

The Sweet Truth About Glycine
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Make Your Collagen Work Better
This is Dr. James Nicolantonio. He’s a doctor of pharmacy, and a research scientist. He has a passion for evidence-based nutrition, and has written numerous books on the subject.
Controversy! Dr. DiNicolatonio’s work has included cardiovascular research, in which field he has made the case for increasing (rather than decreasing) the recommended amount of salt in our diet. This, of course, goes very much against the popular status quo.
We haven’t reviewed that research so we won’t comment on it here, but we thought it worth a mention as a point of interest. We’ll investigate his claims in that regard another time, though!
Today, however, we’ll be looking at his incisive, yet not controversial, work pertaining to collagen and glycine.
A quick recap on collagen
We’ve written about collagen before, and its importance for maintaining… Well, pretty much most of our body, really, buta deficiency in collagen can particularly weaken bones and joints.
On a more surface level, collagen’s also important for healthy elastic skin, and many people take it for that reason alone,
Since collagen is found only in animals, even collagen supplements are animal-based (often marine collagen or bovine collagen). However, if we don’t want to consume those, we can (like most animals) synthesize it ourselves from the relevant amino acids, which we can get from plants (and also laboratories, in some cases).
You can read our previous article about this, here:
We Are Such Stuff As Fish Are Made Of
What does he want us to know about collagen?
We’ll save time and space here: first, he’d like us to know the same as what we said in our article above
However, there is also more:
Let’s assume that your body has collagen to process. You either consumed it, or your body has synthesized it. We’ll skip describing the many steps of collagen synthesis, fascinating as that is, and get to the point:
When our body weaves together collagen fibrils out of the (triple-helical) collagen molecules…
- the cross-linking of the collagen requires lysyl oxidase
- the lysyl oxidase (which we make inside us) deanimates some other amino acids yielding aldehydes that allow the stable cross-links important for the high tensile strength of collagen, but to do that, it requires copper
- in order to use the copper it needs to be in its reduced cuprous form and that requires vitamin C
- but moving it around the body requires vitamin A
So in other words: if you are taking (or synthesizing) collagen, you also need copper and vitamins A and C.
However! Just to make things harder, if you take copper and vitamin C together, it’ll reduce the copper too soon in the wrong place.
Dr. DiNicolantonio therefore advises taking vitamin C after copper, with a 75 minutes gap between them.
What does he want us to know about glycine?
Glycine is one of the amino acids that makes up collagen. Specifically, it makes up every third amino acid in collagen, and even more specifically, it’s also the rate-limiting factor in the formation of glutathione, which is a potent endogenous (i.e., we make it inside us) antioxidant that works hard to fight inflammation inside the body.
What this means: if your joints are prone to inflammation, being glycine-deficient means a double-whammy of woe.
As well as being one of the amino acids most key to collagen production, glycine has another collagen-related role:
First, the problem: as we age, glycated collagen accumulates in the skin and cartilage (that’s bad; there is supposed to be collagen there, but not glycated).
More on glycation and what it is and why it is so bad:
Are You Eating Advanced Glycation End-Products? The Trouble Of The AGEs
Now, the solution: glycine suppresses advanced glycation end products, including the glycation of collagen.
See for example:
With these three important functions of glycine in mind…
Dr. DiNicolantonio therefore advises getting glycine at a dose of 100mg/kg/day. So, if you’re the same size as this rather medium-sized writer, that means 7.2g/day.
Where can I get it?
Glycine is found in many foods, including gelatin for those who eat that, eggs for the vegetarians, and spinach for vegans.
However, if you’d like to simply take it as a supplement, here’s an example product on Amazon
(the above product is not clear whether it’s animal-derived or not, so if that’s important to you, shop around. This writer got some locally that is certified vegan, but is in Europe rather than N. America, which won’t help most of our subscribers)
Note: pure glycine is a white crystalline powder that has the same sweetness as glucose. Indeed, that is how it got its name, from the Greek “γλυκύς”, pronounced /ɡly.kýs/, meaning “sweet”. Yes, same etymology as glucose.
So don’t worry that you’ve been conned if you order it and think “this is sugar!”; it just looks and tastes the same.
That does mean you should buy from a reputable source though, as a con would be very easy!
this does also mean that if you like a little sugar/sweetener in your tea or coffee, glycine can be used as a healthy substitute.
If you don’t like sweet tastes, then, condolences. This writer pours two espresso coffees (love this decaffeinated coffee that actually tastes good), puts the glycine in the first, and then uses the second to get rid of the sweet taste of the first. So that’s one way to do it.
Enjoy (if you can!)

New News From The Centenarian Blue Zones
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
From Blue To Green…
We sometimes write about supercentenarians, which word is usually used in academia to refer to people who are not merely over 100 years of age, but over 110 years. These people can be found in many countries, but places where they have been found to be most populous (as a percentage of the local population) have earned the moniker “Blue Zones”—of which Okinawa and Sardinia are probably the most famous, but there are others too.
This is in contrast to, for example “Red Zones”, a term often used for areas where a particular disease is endemic, or areas where a disease is “merely” epidemic, but particularly rife at present.
In any case, back to the Blue Zones, where people live the longest and healthiest—because the latter part is important too! See also:
- Lifespan: how long we live
- Healthspan: how long we stay healthy (portmanteau of “healthy lifespan”)
Most of our readers don’t live in a Blue Zone (in fact, many live in the US, which is a COVID Red Zone, a diabetes Red Zone, and a heart disease Red Zone), but that doesn’t mean we can’t all take tips from the Blue Zones and apply them, for example:
- The basics: The Blue Zones’ Five Pillars Of Longevity
- Going beyond: The Five Key Traits Of Healthy Aging
You may be wondering… How much good will this do me? And, we do have an answer for that:
When All’s Said And Done, How Likely Are You To Live To 100?
Now that we’re all caught-up…
The news from the Blues
A team of researchers did a big review of observational studies of centenarians and near-centenarians (aged 95+). Why include the near-centenarians, you ask? Well, most of the studies are also longitudinal, and if we’re doing an observational study of the impact of lifestyle factors on a 100-year-old, it’s helpful to know what they’ve been doing recently. Hence nudging the younger-end cutoff a little lower, so as to not begin each study with fresh-faced 100-year-olds whom we know nothing about.
Looking at thousands of centenarians (and near-centenarians, but also including some supercentenarians, up the age of 118), the researchers got a lot of very valuable data, far more than we have room to go into here (do check out the paper at the bottom of this article, if you have time; it’s a treasure trove of data), but one of the key summary findings was a short list of four factors they found contributed the most to extreme longevity:
- A diverse diet with low salt intake: in particular, a wide variety of plant diversity, including protein-rich legumes, though fish featured prominently also. On average they got 57% and 65% of their energy intake from carbohydrates, 12% to 32% from protein, and 27% to 31% from fat. As for salt, they averaged 1.6g of sodium per day, which is well within the WHO’s recommendation of averaging under 2g of sodium per day. As a matter of interest, centenarians in Okinawa itself averaged 1.1g of sodium per day.
- Low medication use: obviously there may be a degree of non-causal association here, i.e. the same people who just happened to be healthier and therefore lived longer, correspondingly took fewer medications—they took fewer medications because they were healthier; they weren’t necessarily healthier because they took fewer medications. That said, overmedication can be a big problem, especially in places with a profit motive like the US, and can increase the risk of harmful drug interactions, and side effects that then need more medications to treat the side effects, as well as direct iatrogenic damage (i.e. this drug treats your condition, but as the cost of harming you in some other way). Naturally, sometimes we really do need meds, but it’s a good reminder to do a meds review with one’s doctor once in a while, and see if everything’s still of benefit.
- Getting good sleep: not shocking, and this one’s not exactly news. But what may be shocking is that 68% of centenarians reported consistently getting enough good-quality sleep. To put that into perspective, only 35% of 10almonds readers reported regularly getting sleep in the 7–9 hours range.
- Rural living environment: more than 75% of the centenarians and near-centenarians lived in rural areas. This is not usually something touted as a Blue Zones thing on lists of Blue zones things, but this review strongly highlighted it as very relevant. In the category of things that are more obvious once it’s pointed out, though, this isn’t necessarily such a difference between “country folk” and “city folk”, so much as the ability to regularly be in green spaces has well-established health benefits physically, mentally, and both combined (such as: neurologically).
And showing that yes, even parks in cities make a significant difference:

Almond Butter vs Cashew Butter – Which is Healthier?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Our Verdict
When comparing almond butter to cashew butter, we picked the almond.
Why?
It’s not just our pro-almonds bias! And of course exact nutritional values may vary depending on the recipe, but we’re using the USDA’s standardized figures which should represent a reasonable average. Specifically, we’re looking at the USDA entries for “[Nut] butter, plain, without salt added”.
In terms of macros, almond butter takes the lead immediately with nearly 2x the protein and over 3x the fiber. In contrast, cashew butter has 1.5x the carbs, and the two nut butters are approximately equal on fat. An easy win for almond butter so far.
When it comes to vitamins, almond butter has more of vitamins A, B2, B3, B5, E, and choline, while cashew butter has more of vitamins B1, B6, and K. Thus, a 6:3 win for almond butter.
In the category of minerals, things are closer, but almond butter has more calcium, magnesium, manganese, phosphorus, and potassium, while cashew butter has more copper, iron, zinc, and selenium. So, a 5:4 win for almond butter.
In short, these three wins for almond butter add up to one total win for almond butter, unless you have a pressing reason to have different priorities in what you’re looking for in terms of nutrition.
Enjoy both, of course! Unless you are allergic, in which case, please don’t.

The Many Benefits Of Taking PQQ
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
We’re going to start this one by quoting directly from the journal “Current Research in Food Science”, because it provides a very convenient list of benefits for us to look at:
- PQQ is a potent antioxidant that supports redox balance and mitochondrial function, vital for energy and health.
- PQQ contributes to lipid metabolism regulation, indicating potential benefits for energy management.
- PQQ supplementation is linked to weight control, improved insulin sensitivity, and may help prevent metabolic disorders.
- PQQ may attenuate inflammation, bolster cognitive and cardiovascular health, and potentially assist in cancer therapies.
Future research should investigate PQQ dosages, long-term outcomes, and its potential for metabolic and cognitive health. The translation of PQQ research into clinical practice could offer new strategies for managing metabolic disorders, enhancing cognitive health, and potentially extending lifespan.
What is it?
It’s a redox-active (and thus antioxidant) quinone molecule, and essential vitamin co-factor, that not only helps mitochondria to do their thing, but also supports the creation of new mitochondria.
For more detail, you can read all about that here: Pyrroloquinoline Quinone, a Redox-Active o-Quinone, Stimulates Mitochondrial Biogenesis by Activating the SIRT1/PGC-1α Signaling Pathway
It’s first and foremost made by bacteria, and/but it’s present in many foods, including kiwi fruit, spinach, celery, soybeans, human breast milk, and mouse breast milk.
You may be wondering why “mouse breast milk” makes the list. The causal reason is simply that research scientists do a lot of work with mice, and so it was discovered. If you would argue it is not a food because it is breast milk from another species, then ask yourself if you would have said the same if it came from a cow or goat—only social convention makes it different!
For any vegans reading: ok, you get a free pass on this one :p
This information sourced from: Pyrroloquinoline Quinone: Its Profile, Effects on the Liver and Implications for Health and Disease Prevention
On which note…
Against non-alcoholic fatty liver disease
From the above-linked study:
❝Antioxidant supplementation can reverse hepatic steatosis, suggesting dietary antioxidants might have potential as therapeutics for nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH).
An extraordinarily potent dietary antioxidant is pyrroloquinoline quinone (PQQ). PQQ is a ubiquitous, natural, and essential bacterial cofactor found in soil, plants, and interstellar dust. The major source of PQQ in mammals is dietary; it is common in leafy vegetables, fruits, and legumes, especially soy, and is found in high concentrations in human and mouse breast milk.
This chapter reviews chemical and biological properties enabling PQQ’s pleiotropic actions, which include modulating multiple signaling pathways directly (NF-κB, JNK, JAK-STAT) and indirectly (Wnt, Notch, Hedgehog, Akt) to improve liver pathophysiology. The role of PQQ in the microbiome is discussed, as PQQ-secreting probiotics ameliorate oxidative stress–induced injury systemwide. A limited number of human trials are summarized, showing safety and efficacy of PQQ❞
…which is all certainly good to see.
Source: Ibid.
Against obesity
And especially, against metabolic obesity, in other words, against the accumulation of visceral and hepatic fat, which are much much worse for the health than subcutaneous fat (that’s the fat you can physically squish and squeeze from the outside with your hands):
❝In addition to inhibiting lipogenesis, PQQ can increase mitochondria number and function, leading to improved lipid metabolism. Besides diet-induced obesity, PQQ ameliorates programing obesity of the offspring through maternal supplementation and alters gut microbiota, which reduces obesity risk.
In obesity progression, PQQ mitigates mitochondrial dysfunction and obesity-associated inflammation, resulting in the amelioration of the progression of obesity co-morbidities, including non-alcoholic fatty liver disease, chronic kidney disease, and Type 2 diabetes.
Overall, PQQ has great potential as an anti-obesity and preventive agent for obesity-related complications.❞
Read in full: Pyrroloquinoline-quinone to reduce fat accumulation and ameliorate obesity progression
Against aging
This one’s particularly interesting, because…
❝PQQ’s modulation of lactate acid and perhaps other dehydrogenases enhance NAD+-dependent sirtuin activity, along with the sirtuin targets, such as PGC-1α, NRF-1, NRF-2 and TFAM; thus, mediating mitochondrial functions. Taken together, current observations suggest vitamin-like PQQ has strong potential as a potent therapeutic nutraceutical❞

Women spend more of their money on health care than men. And no, it’s not just about ‘women’s issues’
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Medicare, Australia’s universal health insurance scheme, guarantees all Australians access to a wide range of health and hospital services at low or no cost.
Although access to the scheme is universal across Australia (regardless of geographic location or socioeconomic status), one analysis suggests women often spend more out-of-pocket on health services than men.
Other research has found men and women spend similar amounts on health care overall, or even that men spend a little more. However, it’s clear women spend a greater proportion of their overall expenditure on health care than men. They’re also more likely to skip or delay medical care due to the cost.
So why do women often spend more of their money on health care, and how can we address this gap?
Elizaveta Galitckaia/Shutterstock Women have more chronic diseases, and access more services
Women are more likely to have a chronic health condition compared to men. They’re also more likely to report having multiple chronic conditions.
While men generally die earlier, women are more likely to spend more of their life living with disease. There are also some conditions which affect women more than men, such as autoimmune conditions (for example, multiple sclerosis and rheumatoid arthritis).
Further, medical treatments can sometimes be less effective for women due to a focus on men in medical research.
These disparities are likely significant in understanding why women access health services more than men.
For example, 88% of women saw a GP in 2021–22 compared to 79% of men.
As the number of GPs offering bulk billing continues to decline, women are likely to need to pay more out-of-pocket, because they see a GP more often.
In 2020–21, 4.3% of women said they had delayed seeing a GP due to cost at least once in the previous 12 months, compared to 2.7% of men.
Data from the Australian Bureau of Statistics has also shown women are more likely to delay or avoid seeing a mental health professional due to cost.
Women are more likely to live with chronic medical conditions than men. Drazen Zigic/Shutterstock Women are also more likely to need prescription medications, owing at least partly to their increased rates of chronic conditions. This adds further out-of-pocket costs. In 2020–21, 62% of women received a prescription, compared to 37% of men.
In the same period, 6.1% of women delayed getting, or did not get prescribed medication because of the cost, compared to 4.9% of men.
Reproductive health conditions
While women are disproportionately affected by chronic health conditions throughout their lifespan, much of the disparity in health-care needs is concentrated between the first period and menopause.
Almost half of women aged over 18 report having experienced chronic pelvic pain in the previous five years. This can be caused by conditions such as endometriosis, dysmenorrhoea (period pain), vulvodynia (vulva pain), and bladder pain.
One in seven women will have a diagnosis of endometriosis by age 49.
Meanwhile, a quarter of all women aged 45–64 report symptoms related to menopause that are significant enough to disrupt their daily life.
All of these conditions can significantly reduce quality of life and increase the need to seek health care, sometimes including surgical treatment.
Of course, conditions like endometriosis don’t just affect women. They also impact trans men, intersex people, and those who are gender diverse.
Diagnosis can be costly
Women often have to wait longer to get a diagnosis for chronic conditions. One preprint study found women wait an average of 134 days (around 4.5 months) longer than men for a diagnosis of a long-term chronic disease.
Delays in diagnosis often result in needing to see more doctors, again increasing the costs.
Despite affecting about as many people as diabetes, it takes an average of between six-and-a-half to eight years to diagnose endometriosis in Australia. This can be attributed to a number of factors including society’s normalisation of women’s pain, poor knowledge about endometriosis among some health professionals, and the lack of affordable, non-invasive methods to accurately diagnose the condition.
There have been recent improvements, with the introduction of Medicare rebates for longer GP consultations of up to 60 minutes. While this is not only for women, this extra time will be valuable in diagnosing and managing complex conditions.
But gender inequality issues still exist in the Medicare Benefits Schedule. For example, both pelvic and breast ultrasound rebates are less than a scan for the scrotum, and no rebate exists for the MRI investigation of a woman’s pelvic pain.
Management can be expensive too
Many chronic conditions, such as endometriosis, which has a wide range of symptoms but no cure, can be very hard to manage. People with endometriosis often use allied health and complementary medicine to help with symptoms.
On average, women are more likely than men to use both complementary therapies and allied health.
While women with chronic conditions can access a chronic disease management plan, which provides Medicare-subsidised visits to a range of allied health services (for example, physiotherapist, psychologist, dietitian), this plan only subsidises five sessions per calendar year. And the reimbursement is usually around 50% or less, so there are still significant out-of-pocket costs.
In the case of chronic pelvic pain, the cost of accessing allied or complementary health services has been found to average A$480.32 across a two-month period (across both those who have a chronic disease management plan and those who don’t).
More spending, less saving
Womens’ health-care needs can also perpetuate financial strain beyond direct health-care costs. For example, women with endometriosis and chronic pelvic pain are often caught in a cycle of needing time off from work to attend medical appointments.
Our preliminary research has shown these repeated requests, combined with the common dismissal of symptoms associated with pelvic pain, means women sometimes face discrimination at work. This can lead to lack of career progression, underemployment, and premature retirement.
More women are prescribed medication than men. PeopleImages.com – Yuri A/Shutterstock Similarly, with 160,000 women entering menopause each year in Australia (and this number expected to increase with population growth), the financial impacts are substantial.
As many as one in four women may either shift to part-time work, take time out of the workforce, or retire early due to menopause, therefore earning less and paying less into their super.
How can we close this gap?
Even though women are more prone to chronic conditions, until relatively recently, much of medical research has been done on men. We’re only now beginning to realise important differences in how men and women experience certain conditions (such as chronic pain).
Investing in women’s health research will be important to improve treatments so women are less burdened by chronic conditions.
In the 2024–25 federal budget, the government committed $160 million towards a women’s health package to tackle gender bias in the health system (including cost disparities), upskill medical professionals, and improve sexual and reproductive care.
While this reform is welcome, continued, long-term investment into women’s health is crucial.

Should We Skip Shampoo?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small 😎
❝What’s the science on “no poo”? Is it really better for hair? There are so many mixed reports out there.❞
First, for any unfamiliar: this is not about constipation; rather, it is about skipping shampoo, and either:
- Using an alternative cleaning agent, such as vinegar and/or sodium bicarbonate
- Using nothing at all, just conditioner when wet and brushing when dry
Let’s examine why the trend became a thing: the thinking went “shampoo does not exist in nature, and most of our body is more or less self-cleaning; shampoos remove oils from hair, and the body has to produce more sebum to compensate, resulting in a rapid cycle of dry and greasy hair”.
Now let’s fact-check each of those:
- shampoo does not exist in nature: true (except in the sense that everything that exists can be argued to exist in nature, since nature encompasses everything—but the point is that shampoo is a purely artificial human invention)
- most of our body is more or less self-cleaning: true, but our hair is not, for the same reason our nails are not: they’re not really a living part of the overall organism that is our body, so much as a keratinous protrusion of neatly stacked and hardened dead cells from our body. Dead things are not self-cleaning.
- shampoos remove oils from hair: true; that is what they were invented for and they do it well
- the body has to produce more sebum to compensate, resulting in a rapid cycle of dry and greasy hair: false; or at least, there is no evidence for this.
Our hair’s natural oils are great at protecting it, and also great at getting dirt stuck in it. For the former reason we want the oil there; for the latter reason, we don’t.
So the trick becomes: how to remove the oil (and thus the dirt stuck in it) and then put clean oil back (but not too much, because we don’t want it greasy, just, shiny and not dry)?
The popular answer is: shampoo to clean the hair, conditioner to put an appropriate amount of oil* back.
*these days, mostly not actually oil, but rather silicon-based substitutes, that do the same job of protecting hair and keeping it shiny and not brittle, without attracting so much dirt. Remember also that silicon is inert and very body safe; its molecules are simply too large to be absorbed, which is why it gets used in hair products, some skin products, and lube.
See also: Water-based Lubricant vs Silicon-based Lubricant – Which is Healthier?
If you go “no poo”, then what will happen is either you dry your hair out much worse by using vinegar or (even worse) bicarbonate of soda, or you just have oil (and any dirt stuck in it) in your hair for the life of the hair. As in, each individual strand of hair has a lifespan, and when it falls out, the dirt will go with it. But until that day, it’s staying with you, oil and dirt and all.
If you use a conditioner after using those “more natural” harsh cleaners* that aren’t shampoo, then you’ll undo a lot of the damage done, and you’ll probably be fine.
*in fact, if you’re going to skip shampoo, then instead of vinegar or bicarbonate of soda, dish soap from your kitchen may actually do less damage, because at least it’s pH-balanced. However, please don’t use that either.
If you’re going to err one way or the other with regard to pH though, erring on the side of slightly acidic is much better than slightly alkaline.

If you use nothing, then brushing a lot will mitigate some of the accumulation of dirt, but honestly, it’s never going to be clean until you clean it.
Our recommendation
When your hair seems dirty, and not before, wash it with a simple shampoo (most have far too many unnecessary ingredients; it just needs a simple detergent, and the rest is basically for marketing; to make it foam completely unnecessarily but people like foam, to make it thicker so it feels more substantial, to make it smell nice, to make it a color that gives us confidence it has ingredients in it, etc).
Then, after rinsing, enjoy a nice conditioner. Again there are usually a lot of unnecessary ingredients, but an argument can be made this time for some being more relevant as unlike with the shampoo, many ingredients are going to remain on your hair after rinsing.
Between washes, if you have long hair, consider putting some hair-friendly oil (such as argan oil or coconut oil) on the tips daily, to avoid split ends.
And if you have tight curly hair, then this advice goes double for you, because it takes a lot longer for natural oils to get from your scalp to the ends of your hair. For those of us with straight hair, it pretty much zips straight on down there within a day or two; not so if you have beautiful 4C curls to take care of!
