Zero frizz is the best hair product there is on this planet. It is 110% better than any product for frizz or curl straightening that you can buy from a salon. (Not to be confused with Frizz Ease which retails at about 3x the price.) You only need a small ammount and it works wonders. i have really thick and wavy/curly hair that has a mind of its own, but with this product i simply dry it and it stays straight and frizz free even in rainy weather. It leaves your hair straight, smooth and shiny and adds weight to fly away hair.
I have thrown every other product I own into the trash and now only use this product.
