What characterizes the Anagen Phase of hair growth?

The Anagen Phase is recognized as the active growth phase of hair. During this time, cells in the hair bulb divide rapidly, contributing to the formation of new hair and an increase in overall hair length. This phase can last several years, depending on various factors like genetic predisposition and health, allowing for significant hair growth.

In contrast, during other phases of hair growth, such as the Catagen Phase, hair detachment occurs, and in the Telogen Phase, hair is in a resting state before it eventually falls out. The Anagen Phase specifically focuses on hair production and growth, which is why this choice is the correct answer when characterizing this important phase in the hair growth cycle.
