The primary hair growth phase is known as the anagen phase. This phase is characterized by active hair growth, during which cells in the hair follicle are rapidly dividing and producing new hair strands. It can last from several years, depending on various factors including genetics, health, and hair type. During this phase, hair lengthens as it is pushed through the scalp.

The anagen phase is crucial because it sets the foundation for the hair’s overall health and strength. The duration of this phase can significantly impact the length and vitality of hair, making it essential in understanding hair growth cycles.

In contrast, the other phases play different roles in the hair cycle. The catagen phase is a transitional stage where hair growth slows down, and the hair follicle shrinks. The telogen phase is a resting phase where hair is shed and the follicle prepares for new growth. Lastly, the exogen phase involves the actual shedding of the hair, marking the end of the growth cycle for individual hairs. Understanding these phases helps in proper hair care and treatment approaches.
