yikes, this discussion has been helpful. I know some dreadheads who go to salons to get their dreads re-tightened and redone. I was even considering maybe going myself...but i'm gathering here that everything they will do i can do at home, right?
My dreads were made by a retail business that specializes only in dreadlocks using the crochet hook and no wax or chemicals etc and because my hair was quite short at the time I got synthetic extensions which were tied in with the crochet hook (no glue) or anything like that, I hated the synthetic extensions so I cut them out, I found a loctician just around the corner from ware I live and went there 4 or 5 Times for maintenance which seamed pointless as a week or so later my was hair back to what it was before I went ... and then I found this site and now I do nothing other than what SE and other members advised me to do.
So now instead of spending money on loctician's I just DONATE to this site ;-)
