When first using this, I did not think it made any difference. Even after washing my hair. But I tried again. I put my head protection on my hair, throughly combed my hair of any tangles and I done about 2 inch sections at a time and I have to admit it worked. It worked so well. I'm so used to using my flat iron all the time and we all know that causes a lot of damage to your hair especially using it daily. I feel this brush straightener is well worth the money. I did notice my hair seemed to be more shiny than when I used my flat iron. It's so easy to use. The only thing I don't like is how the buttons are at the side. I kept pressing them but I found my way around it. Using this brush my hair is soft, shiny, and so easy to straighten now without any damage!
