What is the name of the hair growth phase that is considered the active phase?

The active phase of hair growth is known as the anagen phase. During this phase, hair follicles are actively producing hair. It is characterized by cell division and elongation of the hair shaft, which results in noticeable hair growth. The anagen phase can last several years, depending on various factors such as genetics and health.

Understanding the phases of hair growth is essential in the field of aesthetics and dermatology because it impacts treatments for hair loss and other related conditions. Knowing that anagen is the phase where hair is actively growing can help practitioners choose appropriate interventions for clients seeking to enhance hair growth or manage hair thinning.

The other phases, such as telogen, catagen, and exogen, play different roles in the hair cycle. Telogen is the resting phase, catagen is the transitional phase where follicles shrink, and exogen is related to the shedding of hair. While these phases are important in understanding the overall hair growth cycle, they do not represent the active production of hair that is characteristic of the anagen phase.
