Everyone disses the line, but Pantene's Smooth and Sleek is a good choice if you have serious issues trying to "de-pouf" naturally big hair. L'Oreal's version is called Vive-Smooth Intense- it was not as effective as the Pantene, and felt lower quality- it might work if you do not have a lot of hair to tame, though.
I use the Smooth and Sleek 2n1 and then the separate conditioner afterward...this is a lot of silicone for the hair....but it is the only system that keeps me from looking like Mary Tyler Moore.
Redken's All Soft line is also nice if you are in the mood to splurge.
