Straighting Hair Goes Curly?

on your ghds or in the box there should be a code, if you go on to the Internet site for ghds enter the number and it will tell you if they are real, I've just been talking to a hairdresser who said no matter how stubborn someones hair is they will straighten it.. if they are ok it could mean there is a fault and if you send them bk to the retailer they should give you a new pair. you could also try ghd straightening spray it works wonders.
