Help shaving your legs tips?

3 days isn't bad. A lot of my friends shave daily during the summer. You're just unlucky to have black hair which means you'll have to shave more often. Waxing will make the hair grow slower but you'll have to let it grow out a bit before you can get it waxed again. There are also lotions that slow hair growth and make it less noticeable. Try Aveeno Positively Smooth.
