Final answer:
The Telogen phase is the final, resting stage of the hair growth cycle, lasting 2 to 4 months, during which hair shedding occurs and no new growth happens.
Step-by-step explanation:
The Telogen stage or phase in hair growth is commonly referred to as the resting or shedding phase. This is the final stage of the hair growth cycle, following the anagen phase of active growth and the catagen transitional phase. The Telogen phase is characterized by a period where the hair follicle is at rest, and no new hair growth occurs. This phase lasts about 2 to 4 months, after which the hair is shed, and a new anagen phase commences with the growth of new hair. It is during the Telogen phase that some hair loss is normal, with an average of 50 hairs being shed and replaced each day. However, if the hair loss exceeds the rate of regrowth, it could indicate an underlying issue such as hormonal or dietary changes, aging, or the influence of hormones.
