Telogen Effluvium is a medical disorder that is characterized by the sudden loss of a large amount of hairs. Scalp hairs typically grow for 3 years before they enter the resting phase (telogen), during which the hair root shrivels up and the hair falls out, but in Telogen Effluvium, hair prematurely enters the telogen phase (usually following physiologically or emotionally stressful events). The condition may be divided into acute and chronic types, with the acute resolving without intervention and the chronic persisting in a cyclical fashion. However, both types do not alter the overall thickness of hair or cause baldness. Telogen effluvium should be differentiated from hair shedding that result from drugs or toxins, which instead interrupt hair growth. The condition is harmless and signifies the growth of new hair, and treatments generally have no effect. However, avoiding harsh handling of one's hair or brushing can help.
