To start, I have very thick hair. If you can imagine I have issues with it frizzing and being somewhat untamable. I recently changed shampoos to "Sunsilk De Frizz". Within a week of the change I've noticed my hair is quite a bit softer. Also, there is significantly less frizz. The only downside of this product is it seems to weigh down my hair. Overall, great shampoo. I would definitely recommend "Sunsilk De Frizz" to anyone with problems with frizz control.
