You noticed it in a photograph.
Or in the shower drain. Or the morning your ponytail wrapped around one extra time and something in your chest dropped.
Hair loss is the perimenopause symptom women grieve hardest and mention least. It is visible. It is tied up in how you have understood yourself since you were a girl. And there is no polite way to bring it up, so most women simply do not.
So let us bring it up.
Why hair changes in midlife
Your hair grows in cycles. A long growing phase, a short transitional phase, a resting phase, then shedding and regrowth.
Estrogen extends the growing phase. It is a large part of why hair often looks its best during pregnancy, when estrogen is high, and sheds dramatically afterward when it drops.
Perimenopause is a slower version of that same drop. Less estrogen means a shorter growing phase, so more follicles sit in resting and shedding at any given time, and each new hair comes in a little finer than the one it replaced.
At the same time, the ratio of androgens to estrogen shifts. In women genetically sensitive to it, that drives female pattern hair loss: thinning concentrated at the crown and a part that gradually widens, rather than bald patches.
Two different processes, often running at once. Which is why this is rarely fixed by one product.
Test these four things before you buy anything
I mean this. Women spend hundreds on serums for a problem a blood test would have identified.
Ferritin
The big one. Hair follicles are among the first tissues your body sacrifices when iron is short. Heavy perimenopausal bleeding drains iron over months.
Ask for ferritin, not just hemoglobin. Stored iron can be badly depleted while your blood count looks fine, and many clinicians consider the level needed for healthy hair to be well above the bottom of the standard reference range.
Full thyroid panel
Both underactive and overactive thyroid cause hair loss. Ask for TSH, free T4, free T3, and antibodies, not a lone TSH.
Vitamin D
Involved in follicle cycling, and deficiency is common.
Whether you lost weight fast
Rapid weight loss triggers a specific kind of shedding called telogen effluvium, where a large number of follicles shift into resting at once and then shed together, usually two to four months after the trigger.
This is worth naming plainly because so many women are experiencing it right now and connecting it to nothing.
I lost weight too fast on a GLP-1, and my hair paid for it. That is not an argument against GLP-1 medications, which do enormous good. It is an argument for going slower, protecting protein intake, and knowing the shed is coming so it does not blindside you.
The good news about telogen effluvium: it is usually temporary. Fix the trigger and it grows back.
What actually helps
Protein, seriously
Hair is made of protein. If you are under-eating it, and most women in midlife are, your body deprioritizes hair before almost anything else. This is not a supplement problem, it is a raw materials problem.
Sea buckthorn
The thing that made the visible difference for me during that shed was Sibu sea buckthorn Omega-7. My hair came back.
My honest framing: that is one woman’s result, at the same time as several other changes, and hair naturally recovers from that kind of shed anyway. I am telling you because women in this community ask me constantly what I used. It is not a clinical claim.
Hormone therapy
Addressing the underlying estrogen decline treats the mechanism rather than the symptom. It is not marketed as a hair treatment and results vary, but plenty of women notice their hair steadying once their hormones do. our free directory of 661 hormone-literate providers includes providers offering hair restoration alongside HRT.
Or browse everything we recommend for hormone support, including estrogen patches, DHEA, vaginal estrogen, Thermella for night sweats, and a multivitamin with DIM.
The treatments with the strongest evidence
If this is female pattern hair loss rather than a temporary shed, topical minoxidil has the most robust evidence base of anything available and is over the counter. It takes months and it has to be continued to keep working, but it is the one with real trials behind it.
A dermatologist can also discuss prescription options that are not appropriate to detail on a blog because they depend heavily on your individual situation.
Everything our community uses for hair is here.
What to say to your provider
- “I am losing hair. It started roughly then, and it is diffuse thinning and a widening part.” Bring photos over time.
- “I want ferritin, a full thyroid panel with antibodies, and vitamin D.”
- “I had a period of rapid weight loss.” (If true, this reframes the whole picture.)
- “I want to discuss hormone therapy and a dermatology referral.”
The part I need you to hear
You have changed how you part your hair. You have stopped wearing it up. You have felt vain for caring this much, and then felt worse for feeling vain.
You are allowed to grieve this. It is not shallow to want to look like yourself.
And it is often reversible, which is the part nobody tells you while you stand there looking at the drain.
You are not crazy. It is your hormones.
Start with the labs, then find someone who will treat the cause.
Not medical advice. Always consult a licensed healthcare provider before making changes to your health regimen, especially before starting hormones or combining supplements with existing medications.
You are not crazy. You deserve to feel Awake & Alive.
