Out of curiosity, what do you mean no side effects, all heated tools damage hair, just some less than others. Also, what do you mean by herbal problems? The herbal problems come from herbal botanical products that you can use with a tool and your iron only heats to 300 degrees,,,,you may want to look into a Babyliss iron instead where it goes to 450, heats faster and is specifically created to do less damage to your hair and decrease styling time. I know his post was spam, but the product he is promoting is not a top of the line product and the no side effects confuses me.
Never hurts to call stuff like this out or question peoples claims!!!
