Which phase of hair growth is considered the active stage?

The active stage of hair growth is known as the anagen phase. During this phase, hair follicles are in a state of active division, which means that they are producing new hair cells that contribute to the hair's structure and length. This phase can last for several years, depending on various factors such as genetics and overall health.

In the anagen phase, the hair is firmly anchored in the scalp, and the cells in the bulb of the follicle are rapidly dividing and pushing older cells upward. This results in the visible growth of hair. The length of the anagen phase can vary among individuals and hair types, but it is essential for the continued growth and health of hair.

The other phases, such as telogen, catagen, and exogen, are associated with different stages of the hair life cycle, which includes shedding and resting. In contrast, the anagen phase is characterized by the greatest activity and growth. Understanding this phase is crucial for those studying hair growth and related hair treatments, as it highlights the importance of maintaining a healthy scalp and hair follicle environment to maximize growth potential.
