Hair loss drug-induced

Alopecia induced by physical stress has been termed trichotillomania. This condition occurs from physically pulling or twisting a localized area of hair until noticeable thinning develops. This type of hair loss sometimes occurs in children who unconsciously pull or twist a region of hair. A similar type of hair loss may also occur in adults. Telogen effluvium is a term used to describe a sudden but diffuse hair loss caused by an acute physical or psychological stress. This condition usually lasts only a few months and is reversible. Drugs used in chemotherapy often induce alopecia however, this type of hair loss is also usually reversible and the new hair after chemotherapy can be of a different curvature or color.
