I would think that a iron, probably wouldn't do much more damage than a hair flat iron. Defintatley much more dangerous to use a clothe's iron. that is my professional opinion. I am a hairstylist. So true, most people do bad things to their hair including myself, and I know better! My hair is fried, dyed, and thrown to the side. Well, not excatly, I just think that is a funny saying! lol
