I cut my waxlocks off when they were about ten months old; when they actually started to rot, I don't know. I didn't know they were rotting; a problem had cropped up with my scalp - I had a weird allergic reaction to something -, which was what prompted me to cut the hair off. I sliced into the dreads vertically and combed/pulled the hair apart, and big globs of rotted, matted hair were just dropping off my head. An EXCELLENT example of why NOT to use wax...My mohawk isn't a super skinny one. The line where hair meets shaved kind of lines up with the natural arch of my eyebrows, the outer third of the eyebrows I guess. Ideally I'd just let it go natural, but it might be wiser to use a dread-friendly starter method, only because my boss may not tolerate the wholly unkempt initial phase. So, if it looks quasi-styled right off the bat, it's probably better. I know they look sort of goofy for a while regardless; I just mean it's better if she (and probably more importantly, our clients) can tell I'm starting dreads and not just forgetting to comb my hair, you know?
