Despite the lack of reviews, I went ahead and got the treatment on my hairdresser's recommendation. First, it smells awesome. I got it done about a week ago, and my hair looks and feels so much better. I have long, stick-straight, fine, highlighted hair that seriously lacks any sort of volume and my ends are usually in sad shape. My hair is so much shinier and thicker! I usually have to use a ton of product to keep any style going, which usually makes my hair weighed down and gross-feeling by the end of the day...but now I don't use any and it looks even better. Definitely recommend! I think it was about $20 for the treatment, plus $20 for the shampoo/conditioner--not sure if it's needed, but I didn't have any sulfate-free shampoo so I bought it.
