Doesn't work for all hair types.
Unfortunately this brush didn't straighten my naturally curly hair well at all. The hair on the right side was straightened using the brush at 420 degrees with multiple brush strokes. Hair in the left was straightened with my flat iron at 390 degrees and two pulls through the hair. I was trying to avoid heat damage, not have to increase the temperature with poor results. Sent it back.
