What are the three stages of hair growth?

The three stages of hair growth are Anagen, Catagen, and Telogen.

In the Anagen phase, hair is actively growing and this stage can last several years, depending on various factors including genetics and health. During this time, the hair follicles are deeply rooted, and the hair strand continues to lengthen.

The Catagen phase is a short transition stage that lasts a few weeks. During this time, the hair stops growing and the hair follicle shrinks. This phase is important because it prepares the hair for eventual shedding.

In the Telogen phase, the hair is in a resting state, and this stage can last several months. At this point, the hair can either remain in the follicle and be pushed out by new hair growth or shed naturally.

By identifying these three distinct phases of hair growth, one can better understand the hair growth cycle and how it affects hair health and styling practices. The other options present phases that are either incorrectly named or do not accurately represent the stages of hair growth as recognized in the field of esthetics.
