lol that's like asking does a middle part look good on everyone, of course not. Lots of people have hairstyles that don't look as good on them as another hairstyle or option would. So yes, of course some women and men with dreads don't look that great with them. Also i think some people grow out of hairstyles, like their hairstyle has reached a length that no longer suits them, it's not styled quite right or they've just aged or changed look wise and the look no longer fits them. Maxwell for instance, he's aged, and he's older and dreads just no longer look as good on him as his fade does now. Well..now that i think about it..i'm not sure what you could consider Maxwell's hair..lol it was kind of like dreads is what he said in one interview.
Lost of men and women where i live have dreadlocks, and they stay on top with it. So i guess in my area, to me dreads are more appealing because i see them on all types of people, and they're also really neat so i don't have this pre-conceived notion, or associate with a particular stereotype. The only real stereotype i have is, most of the time on campus, if a guy has dreads, he's a football player. that's about it lol
Oh well, i hope my comment was on track with the topic. But i definitely think some people look great with dreads.
