What is the active stage of hair growth known as?

The active stage of hair growth is known as Anagen. During this phase, hair follicles are actively producing hair. This stage is characterized by rapid cell division and growth of the hair shaft, which can last for several years, depending on the individual and the specific hair type. Anagen is essential for the overall health of hair, as it determines the length and thickness of the hair strands. It contrasts with other stages like Telogen, which is the resting phase, and Catagen, which is a transitional stage where the hair stops growing and detaches from the blood supply. Understanding these cycles is crucial for anyone involved in hair treatments or cosmetic services, especially in contexts where laser hair removal or other hair therapies are applied.
