I've always been "blessed" with thick, wavy hair since being young and have longed for something, other than straightners, to calm and straighten my hair. Using this product does indeed get rid of frizz and make your hair sleek, shiny and straight. Now, it does not keep hair poker straight for three days. My hair, by the end of day two began to go wavy again, but I do like this product. It is very affordable and does make your hair look very shiny and healthy. I think I could be persuaded to buy this again!
