This is an ‘ok’ rotating curling hair dryer [SEP] Soft bristles. Does not put enough torque on the hair shaft to smooth the cuticle on it’s own, so if that’s what you’re looking for, add the heat of a blow dryer. The other option is to leave your hair in a towel for about 35-45 minutes. Work your hair in small sections to keep the barrel from bogging down and make sure to use a good thermal protection product on your hair (doesn’t have to be expensive).
