you can not use it even if your hair is slightly wet so you have to blow dry it first which i hate because i do not like to do [SEP] i was so excited to try out this straightening brush unfortunately it was not everything i had dreamed it would be i have thick ish hair and it did not do much for me first of all you can not use it even if your hair is slightly wet so you have to blow dry it first which i hate because i do not like to do things i mean using a blow dryer and a straightening brush is too much work if you have a mane like mine and it completely loses its mind and goes insanely frizzy after blow drying this brush will not be of much help to you i feel like it does not get hot enough to do actually do what it claims however if you have fine hair this might be something good for you to tryhope this helps cheers
