Review (4/5): Great "Natural" Straight
This did a great job with my thick, wavy hair. It didn't get my hair "stick straight" and I wanted that. If you're expecting your hair to look like it does after you use your flat iron, it will not and you will be disappointed. It left a good amount of the natural body in my hair so that it looked like a natural straight.
The reason I gave it 4 out of 5 stars is because the rubber that is used to line the outside of the brush, protecting your scalp and hands, is great--it does just that. However, it really grips my hair and I think that if you don't clean the brush of your hair between each straightening, it will reduce the effectiveness of the brush over time.
To conclude--I would DEFINITELY buy this brush again. I love it!
