This brush works insanely well! It takes very little work with it to add volume to even the most difficult to tease hair. My hair is very long, heavy, and thick, but also very smooth, straight, and unwilling to take to teasing. The brush only took three small passes of back-combing to create mega volume. The way the bristles are different heights also allowed for me to smooth the top over without ruining the volume. And the handle portion really was useful in grabbing sections of hair. Overall I greatly recommend this brush for volumizing purposes.
