The Thairapy 365 World's Fastest Flat Iron heats to maximum temperature in an unbelievably quick 5 seconds, while maintaining its heat throughout the entire styling process no matter how thick or coarse your hair is. Styling your hair is not only quicker and more efficient, but is healthier for your hair! Because the World's Fastest maintains a consistent temperature even you pass it through the thickest hair, it eliminates the need to pass the iron over each section multiple times. This means that now hair is exposed to heat for less time. By only needing to pass the World's Fast Flat Iron over the hair once, you eliminate unnecessary damage, drying, and breakage, leaving hair healthier, shiner, and more beautiful.
