well i bought some wax strip things and the package said that they'd work better if the hair was 2-5 milimeters long.so almost anywhere between half a centimeter and lower.
Yup 1/8 of an inch long at least. Although, don't let the hairs grow too long either otherwise they tend to simply break instead of being pulled out.
seriously? How many people are going to sit there and measure their leg hair so they can tell they are 1/8 of an inch to wax them?
dont shave for a week or a week and a half depending how fast ur hair grows then it should be good
1/8 of an inch if I remember correctly
