Any other girls have fast growing leg hair ? :(?

Yup mine usually grows back pretty fast after a day or two after shaving. I can't see mine till the late 2nd or 3rd day but you can feel it. It is VERY annoying. Yes it is normal, some girls hair grows faster than others. You just might have to shave more often if you want your legs to stay smooth/if you don't want to see the dark hair growing in. You could always try waxing. I'm not sure if it makes the hair lighter, but it definitely makes your legs look and feel smoother for longer.
