I recently had my hair cut and colored at an exclusive Paul Mitchell salon. They had before and after pictures of peoples hair and some of the pictures were amazing. They had before pictures of very curly hair to after pictures with very straight hair. I asked if they used a chemical to get the hair so straight and smooth. It was all done with this flat iron. Paul Mitchell prides themselves on using the right tools and products to obtain the look you want. I immediately bought this flat iron and it has been amazing on my hair. It has settings for fine hair which I found was really useful for me since my old flat iron was causing breakage on my hair from being too hot. This flat iron literally glides through my hair and it comes out looking smooth and shiny. This flat iron also comes with a two year warranty and Paul Mitchell customer service is amazing. Effectiveness Great flat iron that really gives your hair the smooth and healthy look that you want in your hair.
