What causes chin hairs?
Everyone has hair on their chin and this is perfectly normal. We all have vellus follicles that produce very fine, tiny light-colored hair that is often referred to as “peach fuzz”. Vellus hair serves a purpose, which is to help regulate our body temperature.
During puberty, increased production of the hormone androgen causes these follicles to become bigger and begins making terminal hair, which is longer, coarser, and darker. Everyone’s body produces androgen, but males have higher levels, which is why men usually have more terminal hairs than women.
Your hormone levels shift periodically and throughout your lifetime because of aging, weight gain, and other factors, including pregnancy and menopause.
Even a slight increase in androgen or imbalance between your male and female sex hormones — which everyone has — can result in more terminal hairs in places you may not expect, like your chin.
