What is the first stage of hair growth?

The first stage of hair growth is the anagen phase. During this stage, hair follicles are actively producing hair. This phase is characterized by rapid cell division and growth within the hair bulb, leading to the elongation of the hair shaft. The anagen phase can last for several years, depending on various factors such as genetics and health, and it is typically the longest phase in the hair growth cycle.

This stage sets the foundation for healthy hair growth, as it allows the hair to grow longer and stronger before it eventually moves on to the next stages—in particular, the catagen phase, which is a transitional stage. The health and duration of the anagen phase can significantly impact the overall density and appearance of a person’s hair.
