well, at least...

I used to have little 3" long dreads.

they were nice, but you have to keep 'em waxed and stuff so that you don't get flyaways (frizz) and shit and make 'em look decent.

but watch out, once the roots get dreaded (the roots take probably about a year or so)if you decide you don't want to keep 'em you gotta save your head.

but if the roots don't dread you just soak your head in conditioner and keep coming it and stuff.  eventually they'd come out.  but you will loose hair whilst combing 'em out.
