Dreadlocks can be dyed, however great care must be taken when doing so. Any type of lightening of the hair essentially strips the outer sheathe of the hair follicle which leaves it weaker and more prone to damage. This includes not only bleaching but any lightening. Dying a darker color is much safer and less damaging. In either case you’ll want to be sure to only dye the outside of the dreadlock, do not try to penetrate the dye into the dreadlock – it is unnecessary and causing more stress on your hair. And finally, after you wash all the dye out you should proceed to do a deep cleanse just to be sure, especially when using bleach. You can access our deep cleanse guide here.
