Can You Reverse Gray Hair? A Dermatologist Explains

Betteridge’s Law of Headlines states “any headline that ends in a question mark can be answered by the word no“—it’s not really a universal truth, but it’s true surprisingly often, and, as board certified dermatologist “The Beauty MD” Dr. Sam Ellis explains, it’s true in this case.
But, all is not lost.
Physiological Factors
Hair color is initially determined by genes and gene expression, instructing the body to color it with melanin (brown and black) and/or pheomelanin (blonde and red). If and when the body produces less of those pigments, our hair will go gray.
Factors that affect if/when our hair will go gray include:
- Genetics: primary determinant, essentially a programmed change
- Age: related to the above, but critically, the probability of going gray in any given year increases with age
- Ethnicity: the level of melanin in our skin is an indicator of how long we are likely to maintain melanin in our hair. Black people with the darkest skintones will thus generally go gray last, whereas white people with the lightest skintones will generally go gray first, and so on for a spectrum between the two.
- Medical conditions: immune conditions such as vitiligo, thyroid disease, and pernicious anemia promote an earlier loss of pigmentation
- Stress: oxidative stress, mainly, so factors like smoking will cause earlier graying. But yes, also chronic emotional stress does lead to oxidative stress too. Interestingly, this seems to be more about norepinephrine than cortisol, though.
- Nutrient deficiencies: the body can make a lot of things, but it needs the raw ingredients. Not having the right amounts of important vitamins and minerals will result in a loss of pigmentation (amongst other more serious problems). Vitamins B6, B9, and B12 are talked about in the video, as are iron and zinc. Copper is also needed for some hair colors. Selenium is needed for good hair health in general (but not too much, as an excess of selenium paradoxically causes hair loss), and many related things will stop working properly without adequate magnesium. Hair health will also benefit a lot from plenty of vitamin B7.
So, managing the above factors (where possible; obviously some of the above aren’t things we can influence) will result in maintaining one’s hair pigment for longer. As for texture, by the way, the reason gray hair tends to have a rougher texture is not for the lack of pigment itself, but is due to decreased sebum production. Judicious use of exogenous hair oils (e.g. argan oil, coconut oil, or whatever your preference may be) is a fine way to keep your grays conditioned.
However, once your hair has gone gray, there is no definitive treatment with good evidence for reversing that, at present. Dye it if you want to, or don’t. Many people (including this writer, who has just a couple of streaks of gray herself) find gray hair gives a distinguished look, and such harmless signs of age are a privilege not everyone gets to reach, and thus may be reasonably considered a cause for celebration

Butter vs Margarine
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.
Butter vs Margarine
Yesterday, we asked you for your (health-related) opinion on butter vs margarine, and got the above-depicted, below-described, set of responses:
- A little over 60% said butter is a health food and margarine is basically plastic with trans fats
- A little over 20% said that both are woeful and it’s better to avoid both
- A little over 10% said that margarine is a lighter option, and butter is a fast track to cardiovascular disease.
Comments included (we will summarize/paraphrase, for space):
- “…in moderation, though”
- “I’m vegan so I use vegan butter but I know it’s not great, so I use it sparingly”
- “butter is healthy if and only if it’s grass-fed”
- “margarine has unpronounceable ingredients”
To address those quickly:
- “…in moderation” is a stipulation with which one can rarely go too far wrong
- Same! Speaking for myself (your writer here, hi) and not for the company
- Grass-fed is indeed better; alas that so little of it is grass-fed, in the US!
- Butter contains eicosatrienoic acid, linolelaidic acid, and more*. Sometimes big words don’t mean that something is worse for the health, though!
So, what does the science say?
Butter is a health food: True or False?
True or False, depending on amount! Moderation is definitely key, but we’ll return to that (and why not to have more than a small amount of butter) later. But it is a rich source of many nutrients, iff it’s grass-fed, anyway.
The nutritional profile of something isn’t a thing that’s too contentious, so rather than take too much time on it, in this case we’ll point you back up to the scientific paper we linked above, or if you prefer a pop-science rendering, here’s a nice quick rundown:
7 Reasons to Switch to Grass-Fed Butter
Margarine is basically plastic with trans fats: True or False?
False and usually False now, respectively, contingently.
On the first part: chemically, it’s simply not “basically plastic” and everything in it is digestible
On the second part: it depends on the margarine, and here’s where it pays to read labels. Historically, margarines all used to be high in trans fats (which are indeed woeful for the health). Nowadays, since trans fats have such a (well-earned) bad press, there are increasingly many margarines with low (or no) trans fats, and depending on your country, it may be that all margarines no longer have such:
❝It’s a public health success story. Consumers no longer have to worry about reading product nutritional labels to see if they contain hydrogenated oils and trans fats. They can just know that they no longer do❞
Source: Margarines now nutritionally better than butter after hydrogenated oil ban
So this is one where the science is clear (trans fats are unequivocally bad), but the consumer information is not always (it may be necessary to read labels, to know whether a margarine is conforming to the new guidelines).
Butter is a fast track to cardiovascular disease: True or False?
True or False depending on amount. In moderation, predictably it’s not a big deal.
But for example, the World Health Organization recommends that saturated fats (of which butter is a generous source) make up no more than 10% of our calorie intake:
Source: Saturated fatty acid and trans-fatty acid intake for adults and children: WHO guideline
So if you have a 2000 kcal daily intake, that would mean consuming not more than 200 kcal from butter, which is approximately two tablespoons.
If you’d like a deeper look into the complexities of saturated fats (for and against), you might like our previous main feature specifically about such:

Move – by Caroline Williams
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.
- Get 150 minutes of moderate exercise per week, says the American Heart Association
- There are over 10,000 minutes per week, says the pocket calculator
Is 150/10,000 really the goal here? Really?
For Caroline Williams, the answer is no.
In this book that’s practically a manifesto, she outlines the case that:
- Humans evolved to move
- Industrialization and capitalism scuppered that
- We now spend far too long each day without movement
Furthermore, for Williams this isn’t just an anthropological observation, it’s a problem to be solved, because:
- Our lack of movement is crippling us—literally
- Our stagnation affects not just our bodies, but also our minds
- (again literally—there’s a direct correlation with mental health)
- We urgently need to fix this
So, what now, do we need to move in to the gym and become full-time athletes to clock up enough hours of movement? No.
Williams convincingly argues the case (using data from supercentenarian “blue zones” around the world) that even non-exertive movement is sufficient. In other words, you don’t have to be running; walking is great. You don’t have to be lifting weights; doing the housework or gardening will suffice.
From that foundational axiom, she calls on us to find ways to build our life around movement… rather than production-efficiency and/or convenience. She gives plenty of tips for such too!
Bottom line: some books are “I couldn’t put it down!” books. This one’s more of a “I got the urge to get up and get moving!” book.

Some women’s breasts can’t make enough milk, and the effects can be devastating
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.
Many new mothers worry about their milk supply. For some, support from a breastfeeding counsellor or lactation consultant helps.
Others cannot make enough milk no matter how hard they try. These are women whose breasts are not physically capable of producing enough milk.
Our recently published research gives us clues about breast features that might make it difficult for some women to produce enough milk. Another of our studies shows the devastating consequences for women who dream of breastfeeding but find they cannot.
Some breasts just don’t develop
Unlike other organs, breasts are not fully developed at birth. There are key developmental stages as an embryo, then again during puberty and pregnancy.
At birth, the breast consists of a simple network of ducts. Usually during puberty, the glandular (milk-making) tissue part of the breast begins to develop and the ductal network expands. Then typically, further growth of the ductal network and glandular tissue during pregnancy prepares the breast for lactation.
But our online survey of women who report low milk supply gives us clues to anomalies in how some women’s breasts develop.
We’re not talking about women with small breasts, but women whose glandular tissue (shown in this diagram as “lobules”) is underdeveloped and have a condition called breast hypoplasia.
Sometimes not enough glandular tissue, shown here as lobules, develop.
Tsuyna/ShutterstockWe don’t know how common this is. But it has been linked with lower rates of exclusive breastfeeding.
We also don’t know what causes it, with much of the research conducted in animals and not humans.
However, certain health conditions have been associated with it, including polycystic ovary syndrome and other endocrine (hormonal) conditions. A high body-mass index around the time of puberty may be another indicator.
Could I have breast hypoplasia?
Our survey and other research give clues about who may have breast hypoplasia.
But it’s important to note these characteristics are indicators and do not mean women exhibiting them will definitely be unable to exclusively breastfeed.
Indicators include:
- a wider than usual gap between the breasts
- tubular-shaped (rather than round) breasts
- asymmetric breasts (where the breasts are different sizes or shapes)
- lack of breast growth in pregnancy
- a delay in or absence of breast fullness in the days after giving birth
In our survey, 72% of women with low milk supply had breasts that did not change appearance during pregnancy, and about 70% reported at least one irregular-shaped breast.
The effects
Mothers with low milk supply – whether or not they have breast hyoplasia or some other condition that limits their ability to produce enough milk – report a range of emotions.
Research, including our own, shows this ranges from frustration, confusion and surprise to intense or profound feelings of failure, guilt, grief and despair.
Some mothers describe “breastfeeding grief” – a prolonged sense of loss or failure, due to being unable to connect with and nourish their baby through breastfeeding in the way they had hoped.
These feelings of failure, guilt, grief and despair can trigger symptoms of anxiety and depression for some women.
Feelings of failure, guilt, grief and despair were common.
Bricolage/ShutterstockOne woman told us:
[I became] so angry and upset with my body for not being able to produce enough milk.
Many women’s emotions intensified when they discovered that despite all their hard work, they were still unable to breastfeed their babies as planned. A few women described reaching their “breaking point”, and their experience felt “like death”, “the worst day of [my] life” or “hell”.
One participant told us:
I finally learned that ‘all women make enough milk’ was a lie. No amount of education or determination would make my breasts work. I felt deceived and let down by all my medical providers. How dare they have no answers for me when I desperately just wanted to feed my child naturally.
Others told us how they learned to accept their situation. Some women said they were relieved their infant was “finally satisfied” when they began supplementing with formula. One resolved to:
prioritise time with [my] baby over pumping for such little amounts.
Where to go for help
If you are struggling with low milk supply, it can help to see a lactation consultant for support and to determine the possible cause.
This will involve helping you try different strategies, such as optimising positioning and attachment during breastfeeding, or breastfeeding/expressing more frequently. You may need to consider taking a medication, such as domperidone, to see if your supply increases.
If these strategies do not help, there may be an underlying reason why you can’t make enough milk, such as insufficient glandular tissue (a confirmed inability to make a full supply due to breast hypoplasia).
Even if you have breast hypoplasia, you can still breastfeed by giving your baby extra milk (donor milk or formula) via a bottle or using a supplementer (which involves delivering milk at the breast via a tube linked to a bottle).

Avocado vs Goji Berries – 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 avocado to goji berries, we picked the avocado.
Why?
It takes a special non-dried food to beat a dried food for nutritional density, but avocado manages it!
In terms of macros, avocados have more (famously health) fat; mostly monounsaturated with some polyunsaturated and a little bit of saturated, with some omega-3 and omega-6, in a healthy ratio. Meanwhile, goji berries have more fiber, carbs, and protein. As for glycemic indices, avocados are low GI (40), but goji berries are zero-GI, or, functionally, a negative glycemic index as (notwithstanding their sugar content!) they have an overall lowering effect on blood sugars. In short, both of these fruits have very different things to offer in the macros category, so we’re declaring this round a tie.
In the category of vitamins, avocados have more of vitamins A, B1, B2, B3, B5, B6, B7, B9, E, K, and choline, while goji berries have more vitamin C. A clear win for avocados!
When it comes to minerals, avocados have more copper, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while goji berries have more calcium and iron. Another win for avocados!
In short, enjoy either or both (diversity is good), but for overall nutritional density, avocados win this superfood showdown today.

Who you are and where you live shouldn’t determine your ability to survive cancer
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.
In Canada, nearly everyone has a cancer story to share. It affects one in every two people, and despite improvements in cancer survivorship, one out of every four people affected by cancer still will die from it.
As a scientist dedicated to cancer care, I work directly with patients to reimagine a system that was never designed for them in the first place – a system in which your quality of care depends on social drivers like your appearance, your bank statements and your postal code.
We know that poverty, poor nutrition, housing instability and limited access to education and employment can contribute to both the development and progression of cancer. Quality nutrition and regular exercise reduce cancer risk but are contingent on affordable food options and the ability to stay active in safe, walkable neighbourhoods. Environmental hazards like air pollution and toxic waste elevate the risk of specific cancers, but are contingent on the built environment, laws safeguarding workers and the availability of affordable housing.
On a health-system level, we face implicit biases among care providers, a lack of health workforce competence in addressing the social determinants of health, and services that do not cater to the needs of marginalized individuals.
Indigenous peoples, racialized communities, those with low income and gender diverse individuals face the most discrimination in health care, resulting in inadequate experiences, missed diagnosis and avoidance of care. One patient living in subsidized housing told me, “You get treated like a piece of garbage – you come out and feel twice as bad.”
As Canadians, we benefit from a taxpayer funded health-care system that encompasses cancer care services. The average Canadian enjoys a life expectancy of more than 80 years and Canada boasts high cancer survival rates. While we have made incredible strides in cancer care, we must work together to ensure these benefits are equally shared amongst all people in Canada. We need to redesign systems of care so that they are:
- Anti-oppressive. We must begin by understanding and responding to historical and systemic racism that shapes cancer risk, access to care and quality of life for individuals facing marginalizing conditions. Without tackling the root causes, we will never be able to fully close the cancer care gap. This commitment involves undoing intergenerational trauma and harm through public policies that elevate the living and working conditions of all people.
- Patient-centric. We need to prioritize patient needs, preferences and values in all aspects of their health-care experience. This means tailoring treatments and services to individual patient needs. In policymaking, it involves creating policies that are informed by and responsive to the real-life experiences of patients. In research, it involves engaging patients in the research process and ensuring studies are relevant to and respectful of their unique perspectives and needs. This holistic approach ensures that patients’ perspectives are central to all aspects of health care.
- Socially just. We must strive for a society in which everyone has equal access to resources, opportunities and rights, and systemic inequalities and injustices are actively challenged and addressed. When redesigning the cancer care system, this involves proactive practices that create opportunities for all people, particularly those experiencing the most marginalization, to become involved in systemic health-care decision-making. A system that is responsive to the needs of the most marginalized will ultimately work better for all people.
Who you are, how you look, where you live and how much money you make should never be the difference between life and death. Let us commit to a future in which all people have the resources and support to prevent and treat cancer so that no one is left behind.

Brown Rice Protein: Strengths & Weaknesses
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
❝I had a friend mention that recent research showed Brown Rice Protein Powder can be bad for you, possibly impacting your nutrient absorption. Is this true? I’ve been using it given it’s one of the few plant-based proteins with a full essential amino acid profile!❞
Firstly: we couldn’t find anything to corroborate the “brown rice protein powder [adversely] impacts nutrient absorption” idea, but we suspect that the reason for this belief is: brown rice (not brown rice protein powder) contains phytic acid, which is something of an antinutrient, in that it indeed reduces absorption of various other nutrients.
However, two things are important to note here:
- the phytic acid is found in whole grains, not in protein isolates as found in brown rice protein powder. The protein isolates contain protein… Isolated. No phytates!
- even in the case of eating whole grain rice, the phytic acid content is greatly reduced by two things: soaking and heating (especially if those two things are combined) ← doing this the way described results in bioavailability of nutrients that’s even better than if there were just no phytic acid, albeit it requires you having the time to soak, and do so at temperature.
tl;dr = no, it’s not true, unless there truly is some groundbreaking new research we couldn’t find—it was almost certainly a case of an understandable confusion about phytic acid.
Your question does give us one other thing to mention though:
Brown rice indeed technically contains all 9 essential amino acids, but it’s very low in several of them, most notably lysine.
However, if you use our Tasty Versatile Rice Recipe, the chia seeds we added to the rice have 100x the lysine that brown rice does, and the black pepper also boosts nutrient absorption.
Because your brown rice protein powder is a rice protein powder and not simply rice, it’s possible that they’ve tweaked it to overcome rice’s amino acid deficiencies. But, if you’re looking for a plant-based protein powder that is definitely a complete protein, soy is a very good option assuming you’re not allergic to that:
Amino Acid Compositions Of Soy Protein Isolate
If you’re wondering where to get it, you can see examples of them next to each other on Amazon here:
