Hair thinning in perimenopause and menopause
Somewhere in your 40s the ponytail gets thinner, the parting gets wider, and the brush has more in it than it used to. The NHS lists hair thinning among the symptoms of perimenopause and menopause, and it’s talked about far less than hot flushes.
Why it happens
Hormone changes are thought to play a part. The British Association of Dermatologists says female pattern hair loss is caused by a mix of genetic and hormonal factors. Each affected hair grows back a little finer until some stop. Stress, illness, iron deficiency and thyroid problems can also cause shedding, and they can overlap. It tends to progress slowly and there’s no cure, but treatment can slow it. The pattern is the same as female pattern hair loss and may also overlap with PCOS-related thinning.
What it looks like
Overall thinning rather than patches. The crown and parting go first, the front hairline usually stays. Hair feels finer, dries faster, won’t hold a style. Shedding may rise for a while then settle into a slow thin.
What actually helps
HRT is mainly prescribed for other menopause symptoms, and how much it helps hair isn’t clear, so a GP can discuss it with you. Minoxidil is the main treatment for female pattern hair loss. It may slow thinning and partly restore hair in some women, it usually takes at least 6 months to judge, and it only works while you keep using it. A doctor may also suggest anti-androgen tablets such as spironolactone, which aren’t licensed for this use in the UK. If iron deficiency or a thyroid problem is found, treating it matters, because shedding can come back if the cause isn’t treated. No treatment works for everyone. Minoxidil should be avoided if you’re planning a pregnancy or breastfeeding, and spironolactone should be avoided in pregnancy and breastfeeding. Ask your GP or pharmacist.
Why tracking matters
Every treatment here takes months to show anything, and you’re changing several things at once — HRT, iron, minoxidil, sleep. Without a record you can’t tell what’s working and you’ll stop the right thing at the wrong time. A monthly photo of your parting and crown, same light, same angle, gives you a clear answer and gives your GP something to act on.
