I'm indifferent [SEP] I have extremely thick, somewhat wavy hair. Not curly, not straight. This product didn't 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 &#34;it won't brush through my extremely curly hair.&#34; Well of course it won't! It isn't a magical brush that will glide through hair. When using the heated brush, I used my regular brush with it because the ends wouldn't 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 didn't turn out to be &#34;bone straight&#34; but it's better than when I started. My ends didn't 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 doesn't get hot enough. I have straighteners that (claim to) get 300 degrees Fahrenheit. This product is in Celsius, so I'm not sure of the conversion but it gets up to 230 Celsius. If it was hotter, I'm 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.
