Why Does Low Estrogen Cause Hair Loss in Women?

If DHT causes hair loss, how come women whose estrogen levels drop lose hair? Seems contradictory.

I am not an expert in hormones, but things in medicine are not so binary. Dihydrotestosterone (DHT) is the cause of hair loss in men (not women) who are genetically predisposed to hair loss. You can have a high level of DHT and still have a full head of hair. Women lose hair in a different way than men. There are many causes of hair loss in women. Estrogen levels may play an important part in supporting hair and preventing hair loss in women and when women reach menopause and their estrogen levels drop, they may become victims of their genetics. It doesn’t correlate with DHT in most women.
