I have had this treatment. Previously, I had the keratin treatment, which I loved. It leaves your hair smoother, but you can still make it curl. I don't recommend the brocato treatment, based on my experience. It will take ALL the curl out of your hair, and your hair will no longer hold any curl, at all, no matter what you do. Further, it has left my hair somewhat frizzy and unmanageable. The ends look like they're split (the keratin treament gave me beautiful looking ends). Also, if you color your hair it will take the color out of your hair. I had to wait 2 days before I could get my hair dyed, and in the meantime, I looked awful. The keratin treatment doesn't take the color out. I'm an Ulta customer, and if they don't get the keratin treatment back, I'm going to go to another salon to get it.
