i am indifferent [SEP] i have extremely thick somewhat wavy hair not curly not straight this product did not do much for me i am a tender head also so it was nice to brush through with no pain if you are going to use this here are some tips brush your hair before i keep reading reviews that say it will not brush through my extremely curly hair well of course it will not it is not a magical brush that will glide through hair when using the heated brush i used my regular brush with it because the ends would not get straightened i had to make sure to keep my hair held tight all the way through so i used my regular brush in the other hand my hair did not turn out to be bone straight but it is better than when i started my ends did not get straightened but i also just really need a hair cut so i am not blaming the product for that but it is true what people are saying it does not get hot enough i have straighteners that claim to get degrees fahrenheit this product is in celsius so i am not sure of the conversion but it gets up to celsius if it was hotter i am sure it would work much better basically i will use this a few more times and try to get the hang of it and hopefully like it more
