The average person will grow 15 centimeters per year with about one to one and a half centimeters per month. As with overall body health, a balanced diet, reduced stress and adequate sleep facilitate hair growth. The term average means that some people’s hair grows more slowly and some more quickly and that part comes down to genetics. Your genes will determine the maximum rate at which your hair can grow, and your diet and lifestyle will determine whether your hair will reach that maximum genetic potential for growth.
That being said, there are many people who want instant results and have the money to pay for it. In this case, hair extensions might be the solution. They are expensive, but there are endless varieties to choose from. Lots of women decide to go the extension route when getting married. They can temporarily have long locks for the ceremony and have them taken out after. The extensions usually have to be removed by a trained technician depending upon the method used to integrate them into the hair. If threaded in, the threads need to be cut by a technician to avoid cutting the client’s own hair. If bonded in with adhesive, special products that contain large amounts of oil break down the bond.
Although it is difficult to find the actual numbers in terms of time, we do know that leg hair grows more slowly than head hair. Armpit hair grows much more quickly than leg hair; possibly due to the hair’s role in trapping pheromones to attract the opposite sex. I would like to highlight the fact that shaving does not cause the hair to grow back thicker or longer, nor does it create more follicles. When you are born, the number of hair follicles is fixed; meaning, you don’t grow new ones. The reason why leg hair seems coarser than the hair on your head is because when you shave, you cut the hair horizontally across, creating a flat top. Hair that grows out naturally has a tapered; it comes to a point, so it appears thinner.
Unfortunately, as we age, we do get hairier. Women will often grow hair on their upper lip and chin; or if they already have hair in those places, it will become darker. The same thing happens with men, as they age, they may lose the hair on their head, but new ones will sprout out of their nose and ears. They can also get more back and chest hair. The culprit: testosterone. In women entering menopause, estrogen levels are decreased. Estrogen balances out androgens like testosterone that causes hair growth in places like the upper lip and chin. Without estrogen, hair grows where it didn’t grow before, or it comes in darker. We all have vellum hair that covers our entire body, save for the palms of your hands and the soles of your feet. It is this vellum hair that can become stimulated to grow longer and darker. It is hypothesized that men get hairier as they get older, despite the drop in testosterone levels because of exposure to testosterone over a long period of time.
