What Different Kinds of Hair Loss/Thinning Say About Your Health

Dr. Siobhan Deshauer shows us different kinds of hair loss, what causes them, and what can be done about them:

Many different causes

Here’s how to tell them apart:

  • Alopecia areata is an autoimmune condition where the immune system mistakenly attacks hair follicles, causing hair loss that can occur at any age and affects about 1 in 50 people. It often presents as smooth patches of hair loss and can be treated with steroid injections. Severe cases may require high-dose prednisone, which can restore hair growth over time.
  • Discoid lupus is an autoimmune disease that affects the skin, leading to inflammation, scarring, and permanent hair loss. Unlike alopecia areata, it causes visible damage to the scalp and hair follicles. This type of lupus typically does not involve internal organs, unlike systemic lupus. 
  • Telogen effluvium occurs when a major systemic shock, such as an infection, surgery, or significant stress, triggers many hair follicles to enter the resting phase simultaneously, resulting in delayed hair shedding. The condition is diagnosed with a “hair pull test” and is typically temporary, as the resting phase is followed by normal hair growth phases.
  • Allergic reactions to products, such as hair dye containing PPD, can cause hair loss due to scalp irritation and inflammation. An allergic response may trigger hair follicles to enter a resting phase, leading to hair loss by the same mechanism as telogen effluvium. Treatment with steroids can calm the reaction, and hair usually regrows after recovery.
  • Syphilis, a sexually transmitted infection, can present with varied symptoms, including hair loss in a distinct moth-eaten pattern. Hair loss due to syphilis is reversible and curable with penicillin treatment, with hair regrowth typically occurring a few months after treatment.
  • Biotin deficiency is rare due to its production by gut bacteria and presence in foods such as nuts, seeds, and beans such as soybeans. Deficiency can result from excessive consumption of raw egg whites, which block absorption. Severe deficiency causes hair loss and skin issues but can be treated effectively with biotin supplements.
  • Iron deficiency anemia can cause hair thinning along with symptoms like fatigue and breathlessness. It often results from inadequate dietary intake, but can also occur after heavy menstrual bleeding. Treatment with iron supplements, or blood transfusions in severe cases, can restore both hair and energy levels, leading to significant improvements.
  • Trichotillomania is a psychological condition marked by an uncontrollable urge to pull out one’s hair, often associated with anxiety or depression. Hair patches may show different stages of regrowth. While it can be challenging to manage, the condition can be treated with appropriate psychological and medical support.
  • Traction alopecia results from hairstyles that exert prolonged tension on the hair, causing it to thin or fall out. This type of hair loss can be prevented by reducing the strain on the hair. Loosening hairstyles and giving the scalp a break can help hair regrow over time.
  • Hypothyroidism causes symptoms like fatigue, dry skin, and hair thinning due to insufficient thyroid hormone production—however, it can be managed with diet, and if necessary, thyroid medications.
  • Zinc deficiency may also cause hair loss and a characteristic rash. Treatment with zinc supplements can significantly improve hair growth and other symptoms.
  • Medications, such as chemotherapy drugs, Accutane, and anti-seizure medications like valproic acid, are known to cause hair loss as a side effect. This type of hair loss is often reversible once the medication is stopped.
  • Male pattern hair loss, or androgenic alopecia, is influenced by testosterone and genetic risk factors—which, contrary to popular belief, can come from either or both sides of the family. Early onset, especially before age 40, is linked to an increased risk of heart disease. However, effective treatments are available, and early intervention is beneficial.
  • Female pattern hair loss is basically the same thing as male pattern hair loss (indeed, it is literally still androgenic alopecia), just a) almost always much less severe and b) with a gender-appropriate name. It affects up to 40% of women by age 50 and is characterized by thinning hair at the top of the head. It’s related to hormonal imbalances involving testosterone, such as those seen in PCOS and menopause, amongst other less common causes. Early treatment can be effective, and research is ongoing to develop more targeted therapies.

Dr. Siobhan Deshauer advises, if you’re experiencing hair loss, to monitor other symptoms too if applicable, take photos for tracking, and consult a doctor early for diagnosis and potential treatment.

  • Staring At The Sun – by Dr. Irvin Yalom

    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.

    A quick note first: there are two editions of this book; the content is the same, but the cover is different. So if in your region it has a bright yellow cover and the subtitle is the excitable “Overcoming The Terror Of Death” rather than the more measured “Being At Peace With Your Own Mortality”, that is why; different regional publishers made different choices.

    For most of us, dying is the last thing we want to do. We may fear it; we may ignore it; we may try to beat it—but it’s a constant existential threat whether we want it or not.

    This book is about “death anxiety”, either direct (conscious fear of impending death) or sublimated (not necessarily realising what we’re avoiding thinking about it). In its broadest sense, the fear of death can be described as rational. But angst about it probably won’t help, so this book looks to help us overcome that.

    The style of the book is largely anecdotal, in which the author uses examples from his therapeutic practice to illustrate ways in which the fear of death can manifest, and ways in which it can be managed healthily.

    Subjective criticism: while this author developed existential therapy, many of the ideas in this book lean heavily on the psychodynamic approach derived from Freud, and this reviewer isn’t a fan of that. But nevertheless, many of the examples here are thought-provoking and useful, so it is not too strong a criticism.

    Bottom line: there are many ways to manage one’s mortality, and this book brings attention to a range of possibilities.

  • Discipline is Destiny – by Ryan Holiday

    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’ve previously reviewed another of Holiday’s books, The Daily Stoic, and here is another excellent work from the same author.

    We’re not a philosophy newsletter, but there are some things that make a big difference to physical and mental health, the habits we build, and the path we take in life for better or for worse.

    Self-discipline is one of those things. A lot of the time, we know what we need to do, but knowing isn’t the problem. We need to actually do it! This applies to diet, exercise, sleep, and more.

    Holiday gives us, in a casual easy-reading style, timeless principles to lock in strong discipline and good habits for life.

    The book’s many small chapters, by the way, are excellent for reading a chapter-per-day as a healthy dose of motivation each morning, if you’re so inclined.

    Bottom line: if you’ve noticed that one of the biggest barriers between you and your goals is actually doing the necessary things in a disciplined fashion, then this book will help you become more efficient, and actually get there.

    ❝Questions?❞

    It seems that this week, everyone was so satisfied with our information, that we received no questions! (If you sent one and we somehow missed it, please accept our apologies and do bring our attention to it)

    However, we did receive some expert feedback that we wanted to share because it’s so informative:

    ❝I work at a detox rehab in Mexico, where we can use methods not legal in the United States. Therefore, while much of the linked articles had useful information, I’m in the “trenches” every day, and there’s some information I’d like to share that you may wish to share, with additional information:

    1. Buprenorphine is widely used and ineffective for addiction because it’s synthetic and has many adverse side effects. For heavy drug users it isn’t enough and they still hit the streets for more opioid, resulting in fentanyl deaths. Depending on length of usage and dose, it can take WEEKS to get off of, and it’s extremely difficult.
    2. Ibogaine is the medicine we use to detox people off opiates, alcohol, meth as well as my own specialty, bulimia. It’s psychoactive and it temporarily “resets” the brain to a pre-addictive state. Supplemented by behavior and lifestyle changes, as well as addressing the traumas that led to the addiction is extremely effective.

    Our results are about 50%, meaning the client is free of the substance or behavior 1 year later. Ibogaine isn’t a “magic pill” or cure, it’s an opening tool that makes the difficult work of reclaiming one’s life easier.

    Ibogaine is not something that should be done outside a medical setting. It requires an EKG to ensure the heart is healthy and doesn’t have prolonged QT intervals; also blood testing to ensure organs are functioning (especially the liver) and mineral levels such as magnetic and potassium are where they should be. It is important that this treatment be conducted by experienced doctors or practitioners, and monitoring vital signs constantly is imperative.

    I’m taking time to compose this information because it needs to be shared that there is an option available most people have not heard about.❞

    ~ 10almonds reader (slightly edited for formatting and privacy)

    Thank you for that! Definitely valuable information for people to know, and (if applicable for oneself or perhaps a loved one) ask about when it comes to local options.

    We see it’s also being studied for its potential against other neurological conditions, too:

    ❝The combination of ibogaine and antidepressants produces a synergistic effect in reducing symptoms of psychiatric disorders such as bipolar disorder, depression, schizophrenia, paranoia, anxiety, panic disorder, mania, post-traumatic stress disorder (PTSD), and obsessive–compulsive disorder. Though ibogaine and the antidepressant act in different pathways, together they provide highly efficient therapeutic responses compared to when each of the active agents is used alone.❞

  • Chia Seeds vs Pumpkin Seeds – 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 chia seeds to pumpkin seeds, we picked the chia.

    Why?

    Both are great! But chia is best.

    Note: we’re going to abbreviate them both to “chia” and “pumpkin”, respectively, but we’ll still be referring to the seeds throughout.

    In terms of macros, pumpkin has a little more protein and notably higher carbs, whereas chia has nearly 2x the fiber, as well as more fat, and/but they are famously healthy fats. We’ll call this category a subjective win for chia, though you might disagree if you want to prioritize an extra 2g of protein per 100g (for pumpkin) over an extra 16g of fiber per 100g (for chia). Chia is also vastly preferable for omega-3.

    When it comes to vitamins, pumpkin is marginally higher in vitamin A, while chia is a lot higher in vitamins B1, B2, B3, B9, C, and E. An easy win for chia.

    In the category of minerals, for which pumpkin seeds are so famously a good source, chia has a lot more calcium, copper, iron, magnesium, manganese, phosphorus, and selenium. On the other hand, pumpkin has more potassium and zinc. Still, that’s a 7:2 win for chia.

    Adding up the categories makes for a very compelling win for the humble chia seed.
