Hi, I'm new here! I have caucasian, thin, fine, color-treated kinky/curly hair. I would LOVE a low-maintenance, wavy (NOT stick-straight) look, and today, in my inbox, I got a groupon for a very high end salon in town offering a "Royal Keratin Treatment" for $150.

First, is this a good deal? I've only heard about the treatments in passing, so I'm not sure what they usually run.

Second, will this make my hair stick straight? The picture in the ad shows a girl with very straight hair--which I don't want. I just want looser, less frizzy, more manageable curls.

Can you guys give me your thoughts on this? I want to get some second opinions before I pull the trigger! Thanks!
