Most common type of hair loss among women is androgenetic alopecia, in which hair thins over several months in a predictable triangle pattern. It may be caused by a hormonal imbalance and can be treated with a hair transplant or topical medication, such as Rogaine. Telogen effluvium occurs suddenly and strikes different parts of the scalp randomly. It often occurs after women have gone on or off hormone therapy for menopause or birth control, after pregnancy or illness, during periods of stress or when certain medications, such as blood pressure medication, are started or stopped. Traction alopecia is caused by tight braids or ponytails that pull on the scalp.
