Dyeing your loc extensions will create a vibrant new look. Dreadlock extensions made of synthetic hair cannot be dyed, since the hair is plastic, but you can dye extensions made of human hair. Because dreadlocks act like sponges, you will need at least three times as much dye as you would use on undreaded hair. Dyeing dreadlocks often takes several applications to achieve even color throughout.
Gather the dreads above your ears on top of your head and secure them with a hair band. It will be easier to cover all of your dreads with dye if you work in layers.
Pour three applications of hair dye into a large plastic bowl. Stir the dye for 30 seconds with a plastic spoon to make sure it is evenly mixed.
Put on latex gloves to keep the dye from staining your hands.
Scoop a handful of dye out of the bowl. Squeeze the dye through one dreadlock at a time, working from roots to tips. Ball up the loc in the palm of your hand and open and close your hand several times to help saturate the hair with dye.
Take down the dreads on top of your head and continue squeezing the dye through one loc at a time.
Cover your hair with a plastic shower cap, tucking all your locs into it. Leave the cap on for the amount of time indicated on the dye package. The cap will trap the heat from your head, which helps the dye penetrate.
Rinse your dreads in the shower for twice as long as you normally would when washing. Shampoo your hair, squeezing the suds through the locs. Rinse again until the water runs clear. Rinsing can take up to 15 minutes, but it is important to get all the dye out of the insides of the locs.
