I'm 23 years old girl and for the last year and a half I'm experiencing severe hair loss.I had very thick hair and all of the sudden it just started falling.I have lost hair from all of the scalp but the top is the least affected,no wider part and the sides,temples and especially nape of the neck are hit hard.I'm also experiencing oily skin/hair and excessive hair on face,stomach and breasts.Periods are regular,no cysts and I'm having trouble to gain some weight since I'm pretty skinny.
