What are the stages of hair growth?

• A. Telogen, Metagen, Anagen
• B. Anagen, Catagen, Telogen
• C. Catagen, Tegon, Anagen
• D. Progenitor, Catagen, Anagen

Answer: (B)

The stages of hair growth encompass a cycle that includes anagen, catagen, and telogen. The anagen phase is the active growth stage of hair follicles, during which the cells in the hair bulb divide rapidly. This stage can last several years, resulting in long hair. The majority of hair follicles on a person’s scalp are in the anagen phase at any given time. Following the anagen phase is the catagen phase, which is a transitional stage lasting a few weeks. At this point, the hair stops growing and begins to shrink, and the hair follicle undergoes some changes. The telogen phase is the resting stage in the hair growth cycle. During this phase, hair is eventually shed, and it typically lasts a few months. At the end of this phase, the hair can be replaced by new hair that enters the anagen phase once again, restarting the cycle. Understanding these phases is crucial for estheticians, as this knowledge can influence decisions regarding treatments, hair removal, and even products designed to promote healthy hair growth.
