The telogen phase, often referred to as the resting phase, is the final stage of the hair growth cycle. Following the anagen (growth) and catagen (transition) phases, telogen represents a period of dormancy for individual hair follicles. During this stage, the hair shaft has detached from the dermal papilla, the structure that nourishes the hair root, and is essentially inactive. The hair itself remains in the follicle, anchored, but no longer growing. This phase is typically shorter than the anagen phase, lasting approximately two to four months in humans.

At the end of the telogen phase, the hair follicle prepares to re-enter the anagen phase. A new hair begins to grow beneath the resting telogen hair. As the new hair emerges and starts to push upwards, it dislodges the old telogen hair, leading to natural shedding. This shedding is a normal and essential part of the hair cycle, ensuring that follicles remain healthy and can produce new hair. The duration of the telogen phase can be influenced by various factors, including genetics, hormones, and overall health. A significant increase in the number of hairs entering the telogen phase simultaneously can lead to a condition known as telogen effluvium, characterized by noticeable hair thinning.
