What happens in hair loss depends on its cause.
Inherited hair loss (androgenetic alopecia) often begins between the ages of 12 and 40, and about half the population has some hair loss by about 50 years of age.1, 2 The hair loss generally is gradual. Men tend to lose hair on the front hairline and forehead and on top of the head. Eventually, only hair around the ears, the sides, and back of the head remains. Women with this condition typically have gradual hair thinning throughout the scalp. This type of hair loss must be treated early for hair to regrow.
