this review title is: volume but not great for curls or waves and the content is: not for me or for anyone with waves and curls the brush is unable to straighten close to your scalp line which is a problem for those of us with curly or wavy hairhowever i did notice some extra volume from using the brush and i do not think it was as harsh on my hair as a regular straightener isbut because of my own hair type i do not think it is for me but would be great for anyone with slight waves or straighter hair.there are other information for this review, one is this reviewer did purchase it and the other is 4 people think this review is helpful.
