What phase indicates the transition to hair shedding?

The telogen phase is the resting phase of the hair growth cycle where hair is fully formed but is no longer actively growing. During this phase, the hair follicle is in a resting state, and the hair strand is prepared for eventual shedding. This phase typically lasts around three months, after which the hair is shed. The telogen phase is a crucial part of the hair cycle, as it indicates that the hair has completed its lifecycle and is ready for renewal. Understanding this phase is essential for those in the hair removal field, as knowledge of the hair growth cycle can influence hair removal techniques and timing.

In contrast, the anagen phase is where active hair growth occurs, and the catagen phase signifies a transitional stage between the growth and shedding phases. The progenitor phase is not a standard term used in the hair growth cycle, which emphasizes the importance of recognizing the key phases relevant to hair growth and shedding.
