The telogen phase is the final stage of the hair growth cycle. It is characterized by the hair follicle being in a resting state, and the hair shaft being fully formed and pushed out of the scalp. The telogen phase typically lasts for about 3 months, after which the hair follicle will enter the anagen phase and begin to produce a new hair shaft.
The telogen phase is an important part of the hair growth cycle, as it allows the hair follicle to rest and replenish its energy stores. During this phase, the hair follicle is also less susceptible to damage, which is why hair loss is less common during the telogen phase.
