Rated 3 out of 5 by from It's not as good as it used to be. I love Design Essentials products but in my and my client's opinion, the STS formula has changed. It's not as good as it used to be.

Rated 5 out of 5 by from Amazing product! New favorite product! I will never be without this in my salon again. I don't offer relaxers in my salon because it goes against what I'm trying to accomplish with my clients. This is a great alternative for helping them keep their hair straight and smooth a lot longer.
