Hi Alanah. The back of the head does get really messy during the dreading process. The back rubs on pillows, car seat rests, backs of couches and scarves & tams rub on that section. When this constant friction happens, a knotted mess is made. Mine was also messy back there, but was the first area to start to really show true dreads, not the original formed twist & rip. I would recommend separating any joined hairs or dreads on a daily basis in this area.
I see that you sometimes use a crochet hook to keep it tidy. Did you know that twist & rip dreads need to loosen, loop and knot to turn into mature dreads. Those loops are necessary, so if you are using the hook, you are reversing the process. Hooks break hairs in the dreads, if you are still using it, you may find that one day dreads will start breaking off into your hand due to the broken hairs. A chain is strong, but have a weak link in it and it becomes weak, same with dreads.
Palm rolling is useless and damaging, you won't see the damage right away, but it happens every time you roll the dreads. You do maintenance and still don't like the look, the only maintenance you need to do is regular washing and separating the dreads, that's it, easy huh! Get use to the messy look for the next few months or stay away from a mirror. Be easy on your dreads and you will have healthy hair for a lifetime.
