Let me start off by stating something,
Even though it works great and is what I use as my regular shampoo, The dreadlockshampoo.com soap still leaves residue. All shampoo will leave some level of residue, particularly if you're like me and wash with bore water. I had a problem in my first few months of dreading with shampoo residue building up around the side of my head, leaving the base of those dreads sticky, smelly and looking pretty rank.
I'd been using just dreadlockshampoo.com soap for about four months at that time so I decided to do a BS/ACV wash just to see how it went and it did an awesome job at clearing up the residue that was building up.
I kept doing the BS/ACV wash once every month or two just to keep the build up in check and to generally get a level of cleanliness that the regular shampoo couldn't quite get but over the summer I didn't get time to do a BS/ACV wash because of various reasons.
So I went all up about 5 months without doing a BS/ACV wash and when I finally got a chance to do one, I found a huge amount of dirt and dust had been collecting in my hair.
My point is, it's important to have a regular BS/ACV wash to keep residue and dirt from building up, particularly if you use hard water for your regular washes. find somewhere you can get clean water from, in my town you can get drinking water from almost any tap so I get a large bottle and use that for my washes, if that's not possible then you could also try getting a large bottle of spring water. It'll make the process of locking faster, it'll keep your hair from getting stinky, dirty and sticky. Just do it.
