Perimenopause Hair Loss: What Actually Works (And What Is Just Marketing)

First, the Grief Is Real

There's a specific kind of grief that comes with noticing your hair has changed. You run your brush through and catch more strands than you used to. Your ponytail feels thinner in your hand. The part looks wider in the mirror than it did two years ago.

It's unsettling in a way that's hard to explain to people who haven't experienced it. Hair is tied up in identity, femininity, and how you present yourself to the world. Watching it thin feels like losing something about who you are.

This grief is valid. You're not being vain. Hair loss during perimenopause is a real and common experience, and the emotional weight of it deserves to be taken seriously before we get to any practical information.

Why Your Hair Is Changing: The Hormonal Cause

Hair thinning during perimenopause is primarily driven by two hormonal shifts happening at the same time.

First, estrogen and progesterone, which both support hair growth and extend the growth phase of the hair cycle, begin to fluctuate and decline. When levels drop, more hair follicles shift into the resting and shedding phase earlier than they used to.

Second, the ratio of androgens to estrogen changes. Even though your androgen levels may not actually increase, the relative balance shifts. DHT, a form of testosterone, becomes more influential on hair follicles. DHT can bind to receptors in certain follicles and cause them to shrink over time, producing thinner, shorter strands and eventually going dormant. This is the same mechanism behind male pattern baldness, though the pattern in women typically shows up as diffuse thinning across the top of the scalp rather than a receding hairline.

It's also worth ruling out other contributors. Thyroid dysfunction, iron deficiency, and high stress can all cause similar patterns of hair loss and sometimes coincide with perimenopause. A blood panel can help clarify what's driving what.

What the Evidence Actually Supports

The hair supplement and treatment industry is enormous and largely unregulated. Let's separate what has actual evidence behind it from what is mostly marketing.

Minoxidil, available over the counter as a topical solution or foam, is the most evidence-backed treatment for female pattern hair loss. It extends the growth phase of the hair cycle and has been studied in women specifically. It does not work overnight. Most people need to use it consistently for at least four to six months before seeing noticeable results, and you have to continue using it or the benefit stops. The 2% solution was the original formulation studied in women, though the 5% foam is now widely used and appears at least as effective.

Spironolactone, a prescription medication, blocks androgen receptors and can reduce DHT's effect on hair follicles. It is often used in women with androgenic hair loss. Your dermatologist or gynecologist can assess whether it's appropriate for you.

Ketoconazole shampoo has some evidence suggesting it reduces DHT at the scalp level and may complement other treatments. It's not a standalone solution, but it's low-risk and inexpensive.

The Truth About Supplements

Biotin supplements are frequently marketed for hair loss. The evidence for biotin supplementation improving hair loss is only clear in people who are actually deficient in biotin, which is uncommon. If you eat a varied diet, adding more biotin is unlikely to produce dramatic results. It won't hurt, but managing your expectations matters.

Collagen supplements have become popular and the theory makes some sense biologically, but the direct evidence for oral collagen improving hair density specifically is limited. More research is needed.

Silica, viviscal, and various branded hair supplements contain mixtures of ingredients with varying levels of evidence. Some people report improvement. Controlled trials are generally small and often industry-funded. These products are unlikely to cause harm, but they're also unlikely to be as effective as the marketing suggests.

The honest summary is this: if you want the most evidence-backed approach, minoxidil and addressing any underlying deficiencies through blood work is where to start. Everything else is worth examining with healthy skepticism.

Working With What You Have Right Now

Hair loss can affect your appearance in ways that feel significant, and there are practical things you can do to work with what you have while any treatments take effect.

Volumizing shampoos and conditioners can make a real difference in how your hair looks and feels, even without changing the density. Avoid heavy silicone-based products that weigh hair down. Dry shampoo can add texture and visual volume at the roots.

Your haircut matters more than it used to. Shorter cuts and layered styles tend to look fuller than long, heavy, single-length cuts. A conversation with a hairstylist who has experience with fine or thinning hair can be genuinely useful. This isn't just cosmetic advice. It's a practical accommodation to a real change in your hair's texture and behavior.

Scalp health also supports hair health. Gentle massage increases circulation to follicles. Avoiding excessive heat styling reduces additional damage to already finer strands.

Setting Realistic Expectations

It's worth calibrating your expectations honestly, because unrealistic expectations lead to more distress rather than less.

Most treatments for perimenopause-related hair loss slow the progression and sometimes reverse some thinning, but they rarely restore hair to exactly what it was in your twenties. The goal is generally to stabilize and improve, not to completely undo. Treatments also take time. Four to six months is the typical minimum before you'll see changes with minoxidil. Patience is part of the process.

If you're addressing underlying contributors, like iron deficiency or thyroid dysfunction, correcting those can produce noticeable improvement over time. Some people see meaningful regrowth once these factors are treated. But it takes time and the results vary.

Hormone therapy, for those for whom it's appropriate, sometimes improves hair thinning as a secondary benefit by restoring some of the hormonal support that hair follicles lost. This isn't guaranteed and isn't the primary reason most people start hormone therapy, but it's worth knowing.

Talking to Your Doctor

Thyroid, Iron, and the Tests Worth Getting

Before assuming your hair loss is purely hormonal, it's worth ruling out two conditions that frequently occur alongside perimenopause and cause similar symptoms: thyroid dysfunction and iron deficiency.

Hypothyroidism, an underactive thyroid, causes diffuse hair shedding that looks almost identical to hormonal hair loss. Thyroid dysfunction becomes more common in midlife and is significantly more prevalent in women. A simple blood test measuring TSH, and ideally T3 and T4 as well, can identify it. If thyroid function is the primary driver, treating it often produces noticeable hair improvement.

Iron deficiency, particularly low ferritin (the stored form of iron), is one of the most common and most frequently missed contributors to hair loss in women. Many doctors will tell you your iron is fine based on a standard iron test, but ferritin levels below 50 to 70 are associated with hair shedding even when you're not technically anemic. Ask specifically for your ferritin level and ask what the number is, not just whether it's within the normal range. Normal ranges in lab reports are often quite low.

Correcting iron deficiency through diet and supplementation takes several months to show hair improvement, but for people who are deficient, it can be transformative.

What to Do When Hair Loss Affects Your Confidence

Hair thinning doesn't just affect how you look. It affects how you feel walking into a room. How you feel in photographs. How much mental energy you spend on covering, styling, and worrying.

If hair loss is significantly affecting your confidence or you're spending a lot of cognitive energy managing how others perceive it, that's worth acknowledging directly rather than pushing past it. The mental bandwidth it consumes is real and it doesn't just disappear.

Some people find it helpful to talk openly with someone they trust about what they're experiencing, not to seek solutions, but just to voice it. Naming something and having it witnessed by another person often reduces the shame and isolation around it.

Others find that taking action, even small action, reduces the anxiety. Making the doctor appointment, trying the new haircut, starting the minoxidil, all represent a shift from passive worry to active engagement. That shift in orientation changes the emotional experience significantly even before any visible results appear.

Your hair is part of how you've presented yourself to the world. Grieving its change is legitimate. So is deciding that you're going to do what you can and not let what you can't control determine how you feel about yourself.

Scalp Health and What It Has to Do With Hair Growth

The scalp is skin, and like all skin, it's affected by the hormonal changes of perimenopause. Estrogen decline can reduce scalp oil production, leading to a drier, more sensitive scalp. A dry, inflamed, or clogged scalp creates a less favorable environment for hair follicles.

Scalp massage, done consistently, increases blood circulation to the follicle area. A daily two to three minute massage during shampooing or with a dedicated scalp massager has a small but genuine evidence base for supporting hair retention. It's low-effort and low-cost enough to be worth including in your routine.

Avoiding harsh surfactants in shampoos, particularly sodium lauryl sulfate, reduces scalp irritation for many people with sensitive scalps. Sulfate-free shampoos clean effectively without stripping the scalp as aggressively.

Heat styling damages the hair shaft directly, making already fine hair more prone to breakage. This doesn't change the density at the follicle, but it does affect how much hair appears to be there. Reducing heat, or using a heat protectant consistently, is a low-effort way to preserve the hair you have.

Finally, tight hairstyles, chronic tension from braids, tight ponytails, or extensions, can cause a specific form of hair loss called traction alopecia. This is worth knowing if you regularly wear your hair in styles that pull at the scalp.

Moving Forward

If you are noticing your hair thinning during perimenopause, you're in very common company. It's one of the symptoms that tends to be under-discussed relative to how many people experience it and how much it matters emotionally.

Start with the basics: get blood work to rule out treatable contributors, talk to your doctor about minoxidil if it's appropriate for you, and consider a hair-friendly haircut that works with where your hair is now rather than fighting it.

The emotional piece matters too. Giving yourself permission to grieve the change, while also taking practical action, tends to be more sustainable than pushing through the distress alone or pretending it doesn't bother you.

Your hair may look different than it used to. That's real. It doesn't mean there's nothing you can do about it, and it doesn't mean this is just how things are forever.
