What is the reason for women’s hair loss? A hair growth expert tells all
Hair loss in women is often caused by genetic predisposition and hormonal fluctuations, particularly involving androgens, estrogen, and progesterone. According to dermatologist Michelle Green, treatment typically requires a combination of oral and topical medications, along with in-office procedures, to reduce shedding and promote regrowth. Commonly used ingredients include minoxidil, spironolactone, finasteride, biotin, and saw palmetto, each targeting different aspects of hair follicle health and hormone regulation.
- ▪Female pattern baldness is linked to imbalances in androgen hormones like testosterone and DHT, which can weaken hair follicles.
- ▪Declining estrogen levels during menopause, post-pregnancy, or in conditions like PCOS can contribute to hair thinning and loss.
- ▪Topical and oral minoxidil are used to prolong the hair growth phase and increase thickness, though oral minoxidil is prescribed off-label.

- ▪Finasteride lowers DHT levels but is not FDA-approved for women and should be avoided during pregnancy due to risk of birth defects.
