Unlike the common [[cosmetic]] [[depilation]] of body hair, alopecia tends to be involuntary and unwelcome, e.g., [[androgenic alopecia]]. However, it may also be caused by a psychological compulsion to pull out one's own hair ([[trichotillomania]]) or the unforeseen consequences of voluntary hairstyling routines (mechanical "traction alopecia" from excessively tight [[ponytail|ponytails]] or [[braids]], or burns to the scalp from caustic [[hair relaxer]] solutions or hot [[hair irons]]). In some cases, alopecia is an indication of an underlying medical concern, such as [[Iron deficiency (medicine)|iron deficiency]].<ref name="titleHair loss, balding, hair shedding.
