catagen的用法详解

'

English word \\"catagen\\" is a stage in the cycle of development of a hair follicle. It is the transition stage between the actively growing stage (Anagen) and the resting stage (Telogen).

During Catagen, the hair follicle shrinks and hair growth stops. At the end of this stage, the outer root sheath and the papilla (the base of the hair follicle) break down and the hair follicle is disconnected from the dermal papilla. The hair is no longer nourished by the body and becomes a “club hair”.

Catagen is a very short transition stage that typically lasts only 2–3 weeks. It is important to note that during this stage, hair growth stops and the hair follicle itself becomes dormant. Therefore, this stage is not visible on the surface of the skin, as it is happening deep within the hair follicle below the surface of the skin.

In summary, catagen is a very short transition stage in the hair cycle that occurs between the actively growing stage (Anagen) and the resting stage (Telogen). During Catagen, the hair follicle shrinks and hair growth stops as the hair follicle becomes dormant.
