Hair Loss in Menopause

Hair thinning over the crown, a part that keeps widening, more hair in the brush: this is one of the most upsetting symptoms of menopause and one of the least talked about. Around half of women notice it by their 50s. The cause is hormonal: falling estrogen shortens each hair’s growth phase and removes the counterbalance to androgens at the follicle. It is treatable, especially early, and the first step is telling the two kinds of menopausal hair loss apart and ruling out the common causes that mimic them.

The two patterns

Female pattern hair loss. Gradual, over months to years. Thinning concentrated on the crown and along the part, which widens; the front hairline is usually kept. Hairs become finer and shorter rather than falling out in clumps. This is the androgen-driven pattern that menopause unmasks, and it’s the one that doesn’t reverse without treatment.

Telogen effluvium. Sudden, diffuse shedding all over the scalp, handfuls in the shower, starting two to four months after a trigger: an illness or surgery, a crash diet or rapid weight loss, childbirth, severe stress, iron loss from heavy periods, a thyroid swing, or starting or stopping a medication including hormones. It’s frightening and it usually recovers within six to twelve months once the trigger is dealt with.

Many women in perimenopause have both: a shedding episode on top of gradual pattern thinning.

Why does menopause cause hair loss?

Each hair cycles through a growth phase of several years, a short resting phase, and shedding. Estrogen keeps the growth phase long. As estrogen falls, growth phases shorten and more hairs rest and shed at once. At the same time, estrogen no longer balances the androgens, testosterone and its more potent derivative DHT, that women produce in small amounts. The follicles on the crown are genetically sensitive to those androgens, and under their influence they miniaturise: each cycle produces a finer, shorter hair until it’s barely visible. That’s why the pattern is crown and part, and why the hairline survives.

Heavy perimenopausal periods add iron loss, which on its own causes shedding. Stress, poor sleep and dieting for weight gain add triggers for effluvium on top.

What to rule out first

Cause	Clue	Test
Iron deficiency	Heavy or prolonged periods, fatigue, restless legs	Ferritin and full blood count; aim for ferritin comfortably above the bottom of the range
Thyroid disease	Fatigue, weight change, feeling cold or hot	TSH, free T4
Vitamin D deficiency	Common; aches, low mood	Blood test
Rapid weight loss or low protein	Dieting, bariatric surgery, GLP-1 medications	History; the macros guide sets a protein floor
Medications	Some blood pressure drugs, antidepressants, retinoids, anticoagulants, androgenic progestogens, testosterone	Review with prescriber
Androgen excess	Acne, facial hair, irregular periods before menopause	Testosterone, DHEA-S
Scalp conditions, patchy or scarring loss	Bald patches, itching, scaling, redness, broken hairs	Dermatology; these need a specialist, sometimes a biopsy
Tight hairstyles, heat, chemical treatments	Loss at the hairline and temples	History

Patchy loss, a receding front hairline, or an inflamed scalp are not menopausal patterns and should see a dermatologist.

What helps

In order of evidence, and give any treatment six months before judging it, because hair cycles are slow.

1. Fix iron, thyroid and vitamin D. Correcting low ferritin alone stops shedding for a large share of women.
2. Topical minoxidil. The first-line, FDA-approved treatment for female pattern hair loss: 5% foam or solution once a day to the scalp, indefinitely. It lengthens the growth phase and thickens miniaturised hairs. Expect a shedding increase in the first weeks (the old hairs making way), visible improvement at four to six months, and loss of the gain if you stop.
3. Low-dose oral minoxidil. Increasingly prescribed off-label for women who can’t tolerate or won’t keep up the topical; needs a prescriber because of blood pressure and fluid effects.
4. Spironolactone. An oral anti-androgen, used off-label, that blocks the hormones driving miniaturisation; often combined with minoxidil. Not suitable for everyone and needs monitoring.
5. Hormone therapy. Estrogen lengthens the growth phase and some women on hormone therapy notice fuller hair. It isn’t a hair treatment and isn’t started for hair alone. The choice of progestogen matters: some older progestogens have androgenic activity and can worsen thinning, while micronised progesterone doesn’t. Testosterone therapy and pellets can accelerate pattern loss and are something to raise if you’re considering them.
6. Protein and not under-eating. Hair is low on the body’s priority list; it’s the first thing cut in a deficit.
7. Gentle handling. Loose styles, less heat, no bleaching during a shedding episode. Cosmetic, but it stops adding breakage to loss.
8. Supplements. Biotin only helps if you’re deficient, which is rare, and it interferes with thyroid and other blood tests. Marketed “hair vitamins” have little evidence beyond their iron, D and protein content. Saw palmetto has weak evidence as a mild anti-androgen. See the supplements guide.
9. Platelet-rich plasma and low-level laser have some evidence and real cost; reasonable to discuss with a dermatologist once the basics are in place.

Getting help

Hair loss is a medical symptom, not vanity, and it’s worth raising at any visit. Golden Leaf’s care team can run the blood tests, sort pattern loss from shedding, start minoxidil or refer for spironolactone, and, if you’re considering hormone therapy for other symptoms, choose a regimen that’s kind to your hair. Book a first visit if you’d like that looked at properly.
