Denman Brush

Yesterday, I sent the following email to Denman International, the makers of the infamous Denman Brush (http://www.denmanbrush.com/index.html):

Hello,

I am a professor and I also blog on hair and identity. I'm wondering if there is any information that you can provide that explains why the Denman Brush works so well (especially on curly/kinky hair)?

Thanks!

I am very curious to hear back. I’ve heard that the Denman brush is a great detangler and curl definer. As a loc wearer (for now!), I haven’t had cause to use one in a LONG time (though my Mom used them on my hair back in the day). Do you all use them? What other tools do you use to detangle your hair? To define your curls?
