If you’ve ever had a covering of stubble on your face as you’re clocking out at 5 o’clock you’re probably pretty familiar with this. In fact, if the average man never shaved his beard it would grow to over 30 feet during his lifetime, longer than a killer whale.
Many factors contribute to facial hair growth. You may have experienced some or all of these factors. Facial hair is determined by your genetic makeup and hereditary genes. People will experience facial hair growth at different stages of life, and some might experience worse cases then others.
Facial hair is determined by your hereditary genes. If your parents have facial hair, you’re most likely going to also. Young boys begin to develop facial hair when they hit puberty. And women begin to develop more facial hair when they are older and have started menopause, and in some cases woman may develop facial hair at a younger age if they have a hormone imbalance.
Before puberty, facial hair is a fine, thin type known as vellus, says CNN.com. In men, the main source of the increase in facial hair is from the production of testosterone in their bodies. When boys hit puberty, the fine hair changes and becomes dark and coarse; these hairs are known as terminal. This terminal hair increases all over the body, but mostly it grows more rapidly under the arms, on the face and near the sexual organs.
