Obviously in an ideal world, they'd not want to, but...
My DD is desperate for some, willing to work to earn the money, and is only 13. My friend's a hairdresser and will do them for her, but she said generally it's recommended to wait till they're 16, and think the reason may be to do with risks of hair dye. Is there much evidence for this? If we carefully keep it off the scalp, would it be OK...? I'd much rather do this than DD decide she's off to the chemist to buy a home dye kit etc
TIA
