My mum noticed my leg hairs were a bit dark when I was 13, and told me I'd have to start shaving. I tried shaving, once or twice, and got a dreadful shaving rash (my mum was of the "quick fix" mentality, so it wasn't for years that I realised shaving dry legs with a disposable razor is hardly ideal). It put me off, and I didn't bother for the rest of my teens, although I will admit to being at an all-girls school and being one of the "weird" kids anyway. I shaved under my arms, but never my legs, and only shaped my eyebrows when I occasionally remembered.
Now, okay, I was a weird kid, in many ways, but honestly, I was not unhappy because I had hairy legs and didn't wear make up. No one picked on me. (Well, not about my legs, anyway.) And now, here I am ten years later, 24 and about to get married with two kids. I can't be the only one who just doesn't get why people bother. I shave my legs if I can be bothered or is I was going to a posh do, but other than that? Heck no. I used to wear trousers all the time to cover them up, but in the last couple of years I've stopped bothering. No one notices, and if they do they don't say anything. It also takes ten minutes off my shower time.
My DD is only 1, so a long, looong way from all of this, but I shall certainly not be encouraging her to start shaving and waxing from a young age. I think it is disgusting that so much pressure is put on young girls to conform to some esoteric beauty standard which only photoshop can achieve. I was "lucky" in that I was a bookworm and largely unconcerned with boys, but I know other girls genuinely felt under a lot of pressure to look good when they were at school, and shaving legs and shaping eyebrows came into that. (Along with taking hair straighteners to school even though they were banned, but that's another issue. 
There are so many...)
I would wholeheartedly back any campaign to ban advertising or offering these services to girls under 16 in this country.
