Chin hair, like all body hair, grows in cycles, each with distinct stages: Anagen (Growth Phase): This is when the hair actively grows. Catagen (Transitional Phase): A short phase where hair stops growing and detaches from its blood supply. Telogen (Resting Phase):
The hair rests before shedding and making way for new growth. Several factors affect chin hair growth, with androgens—male hormones present in both men and women—playing a major role. An increase in androgen levels or a , heightened sensitivity to these hormones can stimulate more noticeable facial hair growth, including on the chin.
