What menopause actually does to your hair
Estrogen protects your hair. It lengthens the growth phase and dampens DHT's effects on scalp follicles. When estrogen drops in menopause, that protection vanishes. Androgen levels fall too, but they don't fall as fast as estrogen. So suddenly your scalp is getting relatively more androgen effect than before, and DHT is now unmasked.
DHT locks onto follicle receptors and starts miniaturization: the follicle shrinks, produces thinner, shorter hair, cycle after cycle, until eventually it may stop producing visible hair. This is androgenetic alopecia (AGA). It depends on genetics, but about 50% of women get some degree of it by age 50. Which is why the earlier you catch it, the more you can preserve.
A 2011 S1 guideline by Blumeyer et al. in the Journal of the German Society of Dermatology (JDDG): the first European evidence-based guideline for female AGA. Confirmed that topical minoxidil is the only topical treatment with sufficient RCT evidence to support a recommendation. The guideline also noted that female AGA is frequently underdiagnosed and often misattributed to nutritional deficiency or thyroid disease, delaying effective treatment.
AGA vs the diffuse shedding from your 30s
They feel the same, but they're not. Telogen effluvium (TE) from your 30s is reactive: stress, hormonal shifts, or nutritional gaps trigger it. It sheds evenly everywhere and resolves in 6 to 12 months once the trigger's gone.
AGA is patterned and relentless. In women, it typically shows as thinning across the crown and top, with the front hairline holding strong (different from male-pattern baldness). The parting widens first, usually. Most women wait, thinking it'll resolve. AGA is progressive and doesn't resolve on its own.
Photograph your parting from directly above in the same lighting conditions once a month for three to four months. Progressive widening of the parting. Even subtle. Is more informative than daily shed counts, which vary too much to be meaningful on their own.
What actually works
Minoxidil topical is the gold standard for female AGA. The 2% solution (applied once or twice daily) works. The 5% form used in men shows benefit in women too. It extends the growth phase and fattens the follicles. You'll see results at six months, maximum at 12. Stop using it, and improvement reverses within months. It's maintenance, not a cure. Ask your doctor or dermatologist what concentration is right.
Low-level laser therapy (LLLT) shows promise as an add-on but doesn't have the same solid evidence as minoxidil. PRP injections look interesting in small studies but need bigger trials before anyone should count on it.
Topical minoxidil
Studies support regular topical application. Consult your doctor or dermatologist regarding appropriate concentration and frequency for your situation.
Low-level laser therapy (LLLT)
Multiple small RCTs suggest benefit as an adjunct. Evidence is less consistent than for minoxidil, but it is non-invasive with a good safety profile when used as directed.
PRP injections
Early studies suggest hair density improvements; consult a dermatologist or dermatologist to assess suitability and expected outcomes based on your specific case.
When to see a dermatologist or dermatologist
- Request a trichoscopy (dermatoscopy of the scalp): it visualises follicle miniaturisation and confirms AGA diagnosis more accurately than visual inspection alone.
- Ask your doctor to rule out secondary causes: iron deficiency, thyroid dysfunction, and vitamin D deficiency can all cause or worsen hair thinning and are treatable.
- If AGA is confirmed, ask about minoxidil specifically: not all doctors will offer it proactively for female hair loss.
When to seek specialist input
See a dermatologist or consultant dermatologist if your hair loss is rapid, if it extends to areas beyond the crown and top scalp, if you have associated scalp symptoms (itching, scaling, pain), or if minoxidil has not produced improvement after 12 months of consistent use. Alopecia areata: an autoimmune condition. Can co-exist with AGA and requires different treatment.
