I have think wavy hair and this flat iron is amazing. I decided to step it up and purchase a more expensive iron and it sure performs like the one my hairdresser uses. My hair is smooth and shiny and not frizzy at all. Very easy to use and love the varied heat settings. I wash my hair every other day since it is dry and I only need a quick touch up in the morning for the waves that reappear. Highly recommend this product and you cannot beat the Groupon price, I shopped around!
