I used Nair the first time I wanted to shave my legs, the result was a chemical burn and I think I was about your daughter's age when I did it. I was unsupervised and being "naughty".

I think a girl should start shaving her legs when she's comfortable with the responsibility of it. My mother initially suggested it was when I started my period, but I didn't want to wait that long. I thought I was going to be sixteen and hairy in high school at the rate my body was developing.

my mom wouldn't let me shave until i was in 7th grade (she let me start that summer before). i was 12. she was going to make me wait till i was in middle school before she would let me shave under my arms, but i showed her how long the hair was getting & all, & she let me start shaving... i wanna say about 1/2 way through or near the end of 5th grade. i think i was 11. she gave me a 2 bladed razor & showed me how to do it. i even made her do the 1st few strokes for me both times b/c i was afraid i would cut myself. after she did that, i was fine.

I started fairly young, and found that hair-removing creams caused more irritation than just shaving.

I wouldn't start a kid with Nair or any of those creams, just because of the possibilities of irritation. Start her when you (and she) think it's a good time, but really unless you have a really hairy kid who finds that to be problematic for self-esteem there's probably no reason to encourage shaving any earlier than its going to happen through social pressure, etc.

(And I know plenty of women, including my partner, who rarely if ever shave).

I'd highly advise against nair because it is a chemical-based product and children's skin is way too sensitive for products like that. I started shaving my legs as soon as my hair started getting longer and darker, which was about 9. My mom gave me the choice. When I was little she used to take the blades out of razors and I would shave my legs like her (I was about 5 maybe?) and I would go in and shave my "beard" with my dad too lol. Of course, it wasn't ACTUAL shaving, but I had the idea from a very young age from playing like that, so I knew how it was done without the razor in it, so I was a pro by age 9 when I was ready!

Mine started when she was 11, she had dark leg hair and asked if she could. We bought her an electric shaver and she just loves it.

I would stay away from creams, unless you plan to be there every time, a burn is not fun.

I have burned the crap out of myself with those products! I will let my daughter whenever she asks. I had one of those mothers who did not want me too until I wad 15 or so! Really I hated it. I was very hairy and it was dark, had shave my legs at friends house!

They should start when they are old enough to do it on their own.

Children's skin is really sensitive!

I'd advise to wait until as long as you can (body image issues are more important than a little hair) and then suggest shaving as the first solution, not Nair.

Puberty is a good time to start.
