Hair loss often occurs in women who start and stop birth control. This typically occurs 1-2 months after starting and stopping and can last 4-5 months. For some individuals it lasts 9-12 months.
For the vast majority of individuals, the abnormal shedding eventually stops and returns to normal shedding patterns- even without treatment. However, some women (small minority only) develop a chronic shedding pattern for an extended period of time and some notice that density does not make it back fully on account of an acceleration of underlying androgenetic alopecia.
In summary, most women will experience additional hair shedding for a few months after starting and stopping birth control. The excessive shedding will eventually slow and return to normal for most.
Consultation with a dermatologist is advised if shedding persists after 6 months.
