what age is good to let daughter start shaving.

My daughter is 9 yrs old going to be 10 in May and she is starting to get dark hair on her legs and under her armpits, at what age did you let your girl start shaving. I can't remember when I did, I'm just so afraid that she will get teased about having hairy legs and armpits.
