I was pretty sceptical but brushing my daughter's very long, tangly hair was a nightmare, lots of tears and protests and I am sure it did hurt no matter how gently I tried to do it which was a real pain on school mornings. So I ordered a Tangle Teezer and it looks like a tacky bit of plastic (the pink is, um, VERY pink) but blimey it works. It detangles so easily, makes her shiny and it doesn't hurt. Fantastic! I know this sounds like an ad, but it isn't! Thoroughly recommend.
