flat iron addict [SEP] this brush works just not as well as a flat iron i have thick coarse hair and i have flat ironed for years my objective for ironing is to straighten my hair and seal the cuticle to reduce frizz i used the brush on max heat and still did not feel like it was hot enough i only use on my flat iron picture shows my hair after blow drying after using the brush sectioned my hair and followed the instructions to get best results and after my flat iron the brush did reduce my hair puffiness but not enough and it did not seal the cuticle at all i will be returning the brush as it did not produce the desired affect
