This is the best way to get that straight, shiny, silky, flat hair. If you want body, you'll have to style it further, which could be damaging. It is dramatic and long lasting. It changes the structure of your hair and is damaging though it looks healthy, so invest in something to control the damage.And get someone who knows how to do this; I've had worse results in cheaper salons. If you have a tendency to put your hair through other damaging chemical processes, stay away from this. You will irreparably damage your hair. It almost "melts" off, gives you bald spots if you're sensitive to it, you name it. But if your stylist takes care of you, and you in turn take care of your hair, the result is beautiful. If you're thinking about doing this make it the only chemical process you do to your hair. I had mine done in LA, costing anwhere from $150 - $300 for long hair and it takes 3-6 hours.
