this is not going to replace your flatiron [SEP] i really really wanted to love this but it is not meeting my expectations for a couple of reasonsimmediately upon the first use of the outer edge bristles broke upon straightening my hair my hair is naturally wavy and fine please see pic it shows after blow drying before using the straightening brush so nothing the brush was being put to heavy use on pretty disappointing bristles could be broken that easily i washed conditioned combed applied heat protectant dried brushed and then attempted to straighten my hair with the heated straightening brush the results with spending about the same amount of time as i do with my flat iron it only minimally straightened my hair it was a little more smooth then when i first started but a few waves remained and hair was still a little puffy if you are looking for flatiron straight and smooth sadly this product is not going to meet your expectations
