this review title is: bad and the content is: this product is just like if you had a normal hair brush it did not do anything for my thick hair i imagine if you already almost have straight hair it would do ok but if you do not then this product is useless also this product does not do well with frizzy hair makes it worse instead of making it straighter.there are other information for this review, one is this reviewer did purchase it and the other is 0 people think this review is helpful.
