The Science Behind Chin Hair Growth

Chin hair, like all body hair, grows in three distinct phases:

Anagen (Growth Phase):

This is when the hair actively grows.

Catagen (Transitional Phase):

A short phase where growth stops and the hair detaches from its blood supply.

Telogen (Resting Phase):

The hair rests before shedding, allowing new growth to begin.

Several factors influence chin hair growth, with androgens—male hormones found in both men and women—playing a key role.

Increased androgen levels or heightened sensitivity to these hormones can lead to more noticeable facial hair, especially on the chin.
