No dude! Palm rolling does nothing but breaks hair! Dreads are simple as can be and to do that is to do nothing to them but keep them clean! Why do you insist of doing permanent damage and risk going bald?
Everything you've read on DreadHeadHQ's site or wherever saying you need to palm roll, clockwise rubbing wax and so on are nothing but a bunch of lies you pay a lot of money to get is nothing but lies! Dreads have been around for thousands of years, long before man invented combs/brushes! Just keep them clean and forget about everything else! Let them do what they want to do!
IF yo're so concerned about them then wear a wool tam/sleep on a wool sweater!
Dreads aren't perfect but they're perfect on the person who wear them! Everyone who has dreads are different from the next person! Stop looking for the imperfections cause that's all you'll ever see and you'll get so fed up with them that you'll end up shaving them off!
