I am trying to remember but I think I was around 12 or so when I started shaving my legs. I do not remember when I started to shave my underarms tho and bikini area was much later. My daughter is 11 and worried about her legs looking hairy. Tho it is fine hair, her legs are very white (she has Irish in her and fair skin) and the hair is light brown. So unfortunately yes you can definitely see it. We don't make a deal about it, but she does. I think she is a little young to be using the razor unless I can find a real safe and easy one to use for her. How old were you when you started to shave your legs?
