Is hair loss permanent?

Hair loss from androgenetic alopecia (male pattern baldness) usually is permanent. Although there are extremely rare cases where hair has come back. In cases of Alopecia Areata (hair loss patches in various areas around the scalp), hair can re-grow in the patch areas, but the bald patches will tend to move around and thus re-occur- i.e. occurring in different spaces. Whether or not the hair loss is permanent varies with each individual.
