    Glossary Anagen Phase

    active period of hair growth in the hair cycle

    The Anagen Phase, also known as the growth phase, is the active period of hair growth in the hair cycle. During this phase, hair follicles are actively producing new hair cells, leading to the elongation of the hair shaft. This phase can last anywhere from 2 to 7 years, depending on genetic factors, and determines the maximum length of the hair.
