My DD10 has very long blonde hair. It's extremely thick and quite coarse so it's really tricky to style. She absolutely will not get it cut. She loves having it but because it's so long (and because I'm shit at hair so can't teach her) she can't manage to brush it herself. This is generally not a problem but in a few weeks she's going on a 5 day residential and I'd like her to at least look presentable on the photos! Is there any style I can do that will stay in well for a few days or any treatment that might work? I was thinking of a conditioning mask and then straightening it to make it more manageable? Though as soon as she showers that will be irrelevant. Help!
