Anagen is a phase of the hair growth cycle, also known as the anagen phase. It is the active growth phase of a hair follicle, where the hair shaft is produced and the follicle expands. This phase typically lasts for 2 to 7 years, depending on the individual and the specific hair follicle. During anagen, the hair follicle is nourished by the dermis, which provides the necessary nutrients for hair growth. The hair shaft is composed of keratin, a protein that gives hair its strength and structure. The anagen phase is followed by the catagen phase, where the hair follicle begins to shrink and the hair shaft is released from the follicle. After catagen, the hair enters the telogen phase, where it rests and sheds. The anagen phase is crucial for hair health and growth, as it is during this phase that the majority of the hair shaft is produced. Factors such as genetics, hormones, and overall health can influence the duration and quality of the anagen phase.
