My daughter is 12, she has hair on her legs. And of course she is so self-conscious about it she wants to shave. I really don't think it's necessary, she has legs but it's not bushy it's just hairy. She is really mad, and keeps telling me all her friends are shaving, but is she too young? Should I just let her, will it grow back thicker? Thank you. -Marty JEAN Baker
