Alopecia

Alopecia ( /ˌæləˈpiːʃə/, from Classical Greek ἀλώπηξ, alōpēx) means loss of hair from the head or body. Alopecia can mean baldness, a term generally reserved for pattern alopecia or androgenic alopecia. Compulsive pulling of hair (trichotillomania) can also induce hair loss. Hairstyling routines such as tight ponytails or braids may cause traction alopecia. Both hair relaxer solutions, and hot hair irons can also induce hair loss. In some cases, alopecia is due to underlying medical conditions, such as iron deficiency.
