Description Fusing the power of a straightener with the ease of a hairbrush, amika's Polished Perfection Straightening Brush creates smooth, sleek hair in just a single stroke. This is salon-worthy styling made easy; just run the hot brush through your mane to straighten and add shine, thanks to the brand's double anion spray technology. By depositing millions of negative ions onto your strands, the brush closes the hair cuticle as it straightens, leaving hair flyaway-free and extra glossy. And with customisable temperatures (from 182 degrees for fine, thinner hair through to 230 for curly, course hair), you're easily side-stepping excessive heat damage. How to Use Glide the Polished Perfection Straightening Brush through a section of dry hair (as you would a paddle brush) to reveal smooth style. For best results, slide the brush through the hair at a moderate pace from root to tip. Do not stop in one place for more than 10 seconds to prevent overheating hair.
