During what phase is hair fully developed?

The hair is fully developed during the anagen phase, which is the active growth phase of the hair cycle. During this phase, the hair follicle is in its most stable and functional state, leading to the production of strong and mature strands of hair. The anagen phase can last for several years, depending on various factors including genetics, health, and hormonal balance.

In this phase, the cells in the hair bulb are rapidly dividing and creating new hair shafts. The hair grows continuously during the anagen phase, and it is during this time that the hair is nourished by the blood supply to the follicle, allowing it to reach its maximum length and thickness. Understanding the characteristics of the anagen phase is essential for hair removal practices, as targeting hair during this phase yields the most effective results in terms of long-lasting hair reduction.
