I've just tried it for the first time. I am traumatised.
My hair is certainly straight, but it went on like super glue and I nearly pulled half of it out of my head just trying to blow dry with a round brush. And it's frizzier than it was before using the product. And I was wanting it straight, as in nice bouncy blow dry straight, but what I've got is more like rigid straight helmet hair, Footballers Wives 2001 style. And it looks ok but feels crunchy.
Where did I go wrong? I don't think I overdid the spraying.
Crap product or user error?
