The axillary hair is located under the armpit and is the result of the adrenal glands starting to secrete androgens. Once armpit hair grows, the armpit is often sweaty. Axillary hair is one of the first signs of your puberty. Everyone has long armpit hair, which helps absorb sweat to prevent sweat from flowing down.
