For those of you who use the liquid Dr. Bronners soap on your dreads... How much do you dilute it? I thought I diluted it enough but I have residue on my dreads making them feel dirty. I love dr. bronners but I'm never sure how much to dilute it. I thought that just using a small amount and then rinsing really well would do the trick but I've read that diluting it in water first is what you should do. Maybe I'm just really used to shampoos and soaps that lather when you use them. Would really LOVE some tips! Thanks.
