What are the phases of the hair growth cycle?

The hair growth cycle consists of distinct phases, and the correct answer identifies these as Anagen, Catagen, and Telogen.

Anagen is the active growth phase of hair follicles, during which the hair cells rapidly divide and produce new hair. This phase can last for several years, leading to long hair length, and it accounts for the majority of the hair's life cycle.

Catagen is a transitional phase that occurs after the Anagen phase. It lasts for a short period, usually a few weeks, and marks the end of active growth. During this phase, hair stops growing and the hair follicle begins to shrink.

Telogen is the resting phase of the growth cycle. In this phase, the hair follicle is inactive, and the hair may eventually fall out, making way for new growth to begin anew in the Anagen phase. This phase can last for several months, and it's normal to lose some hairs during this time.

Understanding these phases is crucial for estheticians in various treatments and hair care recommendations, as they can help clients better understand hair growth, shedding, and the effectiveness of certain hair treatments or interventions.
