i think they are on to something here [SEP] i have long fine wavy frizzy hair i can do most straightening with the dryer but i was wanting something that would give it that sleek shiny straight look without using product that makes my hair look greasy i ordered this because i have tried everything else why not this right out of the box i knew they were on to something here a bit heavy but nothing more than a hairdryer i tried brushing my hair with it bad idea it yanked my hair out bad the rubber bristles snag hair very easily but if you piece out hair like you do with a flat iron and work slowly down the hair while firmly holding it taunt then you have something i started flattening with the bristles up instead of down on my scalp and it worked better took some practice but i got it going did the job better than a flat iron still a bit concerned about the hair it pulls out but i think with practice i will get better at it i think this is a winner just do not brush your hair with it unless you want to go bald
