Always late to the party as per usual but I am considering this. My hair is longish (below shoulder), quite fine, highlighted; used to have a decent wave to it but not anymore; now it's just frizzy if I don't blow dry it straight. Even when I do, any humidity in the air makes it puff up and it really looks ugly.
I have never liked poker straight hair though, and I am worried that the keratin smoothing system will make my hair look lank and flat.
I would love to hear opinions of anyone who's had it done recently.
