What are the phases of hair growth?

The phases of hair growth are correctly identified as anagen, catagen, and telogen.

During the anagen phase, which is the growth phase, hair actively forms and can last for several years. This period is critical for the development of healthy hair strands, as it is when the hair follicle is actively producing new cells.

Following this is the catagen phase, which is a transitional stage lasting a few weeks. During catagen, the hair stops growing and begins to detach from its blood supply. This phase represents a shift where the hair follicle prepares for the next phase of the cycle.

Finally, the telogen phase is the resting and shedding phase that can last for several months. In this phase, old hair is shed and eventually replaced by new hair when the cycle returns to the anagen phase.

Understanding these phases is essential for comprehending hair growth patterns and hair health. Each phase plays a crucial role in the lifecycle of hair and highlights how hair undergoes cyclic changes, influencing both hair loss and regrowth.
