The dormant or shedding phase of hair is known as the:

The telogen phase is recognized as the dormant or shedding phase of hair growth. During this phase, the hair follicle is in a resting state, and the hair shaft is no longer actively growing. Instead, the hair may remain in the follicle for several months before eventually shedding to make way for new hair growth in the anagen phase. This cycle is a natural part of the hair growth process, allowing for the renewal of hair while ensuring that the scalp and hair remain healthy.

The distinction between the telogen phase and the other stages is essential for understanding the hair growth cycle. The anagen phase is when hair actively grows; the catagen phase marks the transitional period where hair growth stops, and the hair follicle begins to shrink, but it is not a resting phase. The term "increase phase" is not a recognized phase in the context of the hair growth cycle. Understanding these phases is crucial for professionals in hair removal and hair care, as it helps them determine the best timing for various treatments.
