Makes your hair shiny----Works great on damp or towel dried hair. It gives you natural healthy silky looks rather than flat burnt look and leaves your hair easy to manage.
The most important thing to remembe with this brush is that you need to hold your hair taut and go slowly and ensure that your hair is in the bristles because that is what does the straightening. 
You can not run this brush through your hair like a regular brush an expect great results.If you go slowly you can get your ends straight also.
 I would advise some of those heat gloves because the hair gets hot. This brush goes up to 450 degrees which is what most good flat irons go to. But this brush isn't damaging like a flat iron because your hair isn't being smashed between hot plates. 
You must hold your hair taut and you must pass slowly. 
You also must not use too much hair or you won't get the silky 1 to 2 pass results.
