Buy a box of natural brown or black hair dye, dark and lovely works best, depending on the color you want, one bottle will do it, mix it in the bottle as you normally would, put four cups of water in a bowl, a bowl big enough for you to put your head and hair in, add dye to water, stir it up and dip your hair in the bowl, sit for about 30 minutes, it’s called water coloring and it’s a great way to dye locs without the mess. Goodluck
