Is the instyler better then a straightner?

Yes, because a flat iron compresses, mashes, and then literally bakes your hair between two extremely hot plates. By pressing and ironing your hair strands together, a flat iron gives you hair that is about as full and bouncy as a sheet of paper. The Instyler's rotating heated polishing cylinder gives your hair the heat it needs to help style and straighten -- and because the cylinder is constantly moving, it won't "press and bake" like a traditional flat iron. The Instyler's bristles comb and separate your hair, while the rotating motion of the heated cylinder literally polishes each hair strand with a smooth "buffing" action, delivering much more sheen, shine and body. This polishing allows the Instyler to actually use less heat than a flat iron and get much better results. Plus, you can actually use the Instyler as a styling tool since the curvature of the heated polishing cylinder allows you to do flips, curls and add volume that you just can't do with a flat iron.
