My mum was a beauty therapist and did my waxing (eyebrows, bikini line, legs, underarm, upper lip) from when I was about 13. She's very anti shaving, shaved all through her early 20's and is on the shaving-causes-thick-hair camp. Now, after waxing for about 30 years, she hardly grows hair on her legs or underarms at all. No idea if a 50+ year old woman who shaved would be the same. For me, waxing didn't work. I'm very hairy, with pale skin and dark hair. I waxed until I was 17, because my mum wouldn't allow shaving. The hair would start to grow back after 2 days, and would be very noticeable after 4 days...and the hair wouldn't be long enough to wax again until 1.5 weeks. So in the summer I'd have a very small amount of time hair free. Shaving is easier for me, I can shave every day. If I shave in the morning, by the next morning it's grown enough that you can see it. I remember sneaking my first razor and not knowing what to do and cutting my legs up something awful. Honestly, I think I'll just let my girls shave. It can be their choice. If they want to wax, I can teach them to do their own waxing (I do my own eyebrows, and can do my own legs, underarms and bikini line). It's very inexpensive to do your own waxing at home. I'll probably encourage DD1 to hold off on her legs for a bit, because she's blonde and has blonde fine hair on her legs, she probably won't need toad much as DD2, who is dark haired and very hairy.
