Review title is Volume, but not great for curls or waves. [SEP] 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 hair.<br />However, I did notice some extra volume from using the brush and I don't think it was as harsh on my hair as a regular straightener is.<br />But because of my own hair type, I don't think it's for me, but would be great for anyone with slight waves or straighter hair.
