viri - they look awesome!
different people get dreads for different reasons.
some people get them for the look of neat, manicured dreads.
some people like them big and fuzzy.
and some people don't even care about the look, and are doing it for the journey.
perhaps the girl is enjoying just leaving her hair to do whatever, and defying social conventions of having hair specifically to "look good".
it may be much more about letting herself be natural than looking a certain way. and beauty is of course in the eye of the beholder.
many people find being natural far more attractive than people who shave and preen and apply all the time.
this is just a guess, though. there are ALL sorts of reasons that people wind up with dreads, and all different types of dreads. they're not all meant to look perfect.
