Most men's hair grows in a year, whereas women's hair might take up to three years. You'll see the finest benefits after around six months of shaving your legs. However, if you want full coverage after just one month, you should consider growing a beard or using a product such as Leg Asylum to help things along. Hair on your legs will once again start to grow after you stop shaving them. But since your body is still learning how to cope with hair growth, you may also get a few more hairs than usual. This is called an "after-shave effect". The average man's leg has about 100 hairs on it. Most of these are at the top of the foot, with some further down towards the heel. The hair tends to be longer at the top of the foot and shorter toward the heel. Only about 10 percent of men have beardless legs. The other 90 percent have some form of hair on their legs. If you're worried about how long it will take for your hair to grow back, don't worry about it. As long as you aren't going over the same part of your body every day, your skin will eventually figure out what time it is and start producing new hair.
