having dyed my dreads, yes, exactly as you would your normal hair.
grab the dye on a gloved hand and palm-roll it over the dread, squishing it to make sure it gets into the hair rather than just coating the outside.
word of warning: if you're using the conditioning, direct dyes (bright colours) over freshly formed dreads it can cause them to un-ravel a bit, so they may need a back-comb after dying.
Some other random things I learned having dreads:
- wash your hair with bicarbonate of soda mixed with water, if you can't get hold of this, use washing up liquid (dish soap) or clarifying shampoo
- don't use wax, it just seems to cause issues
- back-comb, palm-roll, repeat forever
- you will have a huge, fluffy mess on your head for a bit, invest in a crochet hook and use it to tighten your dreads (the best thing I did while I had dreads)
-super-clean knotted hair. wash it and tighten up the knots, it doesn't need anything else (unless you're colouring them)
- super-damaged hair leads to brilliant dreadlocks, bleach the hell out of it!
