In search of good shampoo/conditioner

Thickness wouldn't hurt> as well.I have fine dark curls that get weighed down easily too and have found that using a build-up remover shampoo weekly really works. Neutrogena is good. After years of trying different hair styles, my hair looks much thicker cut just to my hair line at the back and all one length, with no layers at all and no fringe. Use products without silicones as they really weigh down the hair and condition your hair perhaps every other wash. Do you have Sam McKnight products in the US? His Big Mouse leaves my curls shiny and smooth, but with plenty of body. Do you use a diffuser when you dry your hair? I'm thirty three, and I've battled with my hair for as long as I can remember, wishing it was thick and straight, but at last I'm happy with what I've got!
