GlossaryExogen

final phase of hair cycle when hair sheds naturally

Exogen is the final phase of the hair growth cycle, during which the hair shaft is released from the follicle and sheds naturally. This phase follows the telogen phase and precedes the growth of new hair in the anagen phase. Understanding exogen is crucial for professionals dealing with hair loss conditions, as it helps in diagnosing and treating various forms of alopecia.
