What phase is referred to as the resting phase of hair?

The phase known as the resting phase of hair is called telogen. During the telogen phase, hair is not actively growing; it is in a dormant state where the hair follicle is at rest. This phase can last several weeks to months and typically leads to the eventual shedding of hair.

Understanding the hair growth cycle is essential for cosmetology, as it informs various aspects of hair care and treatment. The hair growth cycle consists of three phases: anagen (growth), catagen (transitional), and telogen (resting). In the anagen phase, the hair is actively growing, while in the catagen phase, there is a short transition where growth slows and the follicle begins to shrink. The telogen phase is crucial for the overall health of the hair, as it allows for renewal and prepares the cycle to restart with new hair growth.

Knowledge of these phases helps cosmetologists provide better advice on hair care, understand hair loss issues, and manage treatments appropriately based on the current state of the client's hair growth cycle.
