The anagen phase is the active growth phase of hair. During this stage, hair follicles are highly active, and new hair cells are produced, leading to the growth of the hair shaft. This phase can last for several years, depending on factors like genetics and overall health, which significantly influences the length and growth rate of the hair. As a result, the majority of the hair on a person's head is in the anagen phase at any given time, contributing to the continuous growth of hair.

In contrast, the other phases like telogen and catagen involve either a resting period or a transitional stage. The telogen phase is when hair growth stops, and the hair eventually sheds. The catagen phase is a short transitional period following anagen where the hair stops growing, and the follicle begins to shrink. Understanding these phases helps in recognizing the hair growth cycle and the factors that can affect hair health and growth. Thus, the anagen phase is crucial for anyone looking to maintain or encourage hair growth.
