What is the resting phase of hair growth known as?

The resting phase of hair growth is known as telogen. During this stage, the hair follicle is in a state of rest. It is a critical phase in the hair growth cycle because, at this point, the hair is not actively growing or shedding. Typically, hair strands can remain in the telogen phase for several weeks to a few months before they are eventually shed and replaced by new hair from follicles that are re-entering the anagen phase, which is the active growth period of hair.

Understanding the hair growth cycle involves recognizing the significance of each phase, with telogen serving as the resting state that prepares the hair for the next cycle of growth. This knowledge is essential in various fields, including cosmetology and dermatology, as it informs practices related to hair care and treatment.
