If not properly used, the Denman can rip your hair right out of your head. So, I did some research and found a few videos demonstrating how to modify the Denman to allow the bristles to work through the hair more easily. The Denman can be found at Sally Beauty Supply for around $10.....yes expensive, but worth it. I bought the Denman 5-row classic styling brush.
Here's how to modify your Denman:
-Separate the bristles from the base of the brush by gently sliding the bristle casing upwards
-Remove every other row of bristles
-Close the bristle casing and slide back into the brush
