Cannot recommend this product enough - it's ruddy fabulous.
My hair is long and thick and is pretty darn heavy, so even after endless back-combing, by the end of the day, my hair is flat and limp.
Was out with some friends on Saturday night, and one of the girls had gorgeous big volumous hair. She told me it was because she'd used Babyliss Big hair. Well, I bought it yesterday and it's bloody amazing. I didn't even need to straighten my hair to get the frizz out. My hair is shiny and bouncy and I look like a film star - well, sort of, I *do* still have a pleb's face.
Anyway, if you want big hair and don't want to spend hours at the salon getting it, I'd buy this. It's £50 on Amazon, but Curry's have got it for £35 at the moment.
