It not only straightens but is an amazing detangler!
I have very thick 4c hair and this product is amazing. I love that it dries my hair while detangling and straightening it.  Normally it would take me 1 1/2 hours to wash, detangle, blow-dry and straighten. This straightening brush has cut my time in half. It is easy to use and gets hot in a few minutes.  It doesn't burn my hair and removes frizz.
