I got this comb
http://www.needsndesires.com/images/untanglercomb.jpgfrom Needs N Desires. (mine is red) It was so inexpensive I thought I would try it. The teeth rotate 350 degrees to help get tangles out. I tried it today on my two with very thick hair and it went through their hair SO well! I have a CC comb and I really like it, but this comb just went through the tangles. Mind you, there were no big mats or anything - just the tangles from sleeping and having thick hair. It also collects loose hair. So far, so good!
