Backcombing is the most widely used method for making dreadlocks. The process takes several hours and varies depending on the length, thickness and texture of your hair. At least 4 inches of hair is needed. Asking a few people to help you will save time and make the process less tiring. Backcombing works on most hair types, though thick or oily hair will be the most difficult to work with, as it will slide more easily out of the knots that form the dreadlocks.
Wash your hair with dreadlock shampoo, starting two weeks before you put the dreadlocks in, if possible. Do not use conditioner. Make sure your hair is completely dry before starting your dreadlocks.
Section your hair into 1- to 2-inch-square sections depending on how thick you want your dreadlocks to be. If you want a side part, start with a row down the center of your head, if you want a middle part, make two rows starting from the middle part. Continue sectioning your entire head; hold the sectioned hair in place with clips or rubber bands.
Remove the rubber band from one section and start backcombing. Start at least 1 inch from the scalp, use your dread comb to comb the section of hair towards your head. Move the comb up about 2 inches and repeat. As you backcomb, rotate the hair you are holding from side to side to help create a circular shape as the dreadlock forms.
Place a rubber band at the tip of the dreadlock and another rubber band a half an inch from the base of your scalp, to help the dread stay in place. Don't place the band too tightly or too close to the scalp, as it can cause soreness; however, the band at the tip should be fairly tight.
Repeat Steps 3 and 4 on each section of hair. Take a break every 25 to 30 minutes to prevent neck and back pain, as well as soreness in your hands.
Apply dread wax starting half an inch from the base of each dread. Use a pea-sized amount for every 3 inches; rub the wax between your fingers to warm it up and work it into the dread, rolling the hair between your fingers until it is gone. After the full strand is waxed, roll the dread between your palms for 30 seconds.
Continue this process with each dread. If your dreads feel too waxy, you can finish by using a hairdryer over your whole head for a few minutes to melt the wax into your hair.
Wash your dreadlocks every two to three days, and rub new growth against your scalp in a circular motion to help form new knots at the roots. A sculpting hook can be used to pull loose hair back into the dreadlocks. Palm roll each dread for 30 seconds. Hooking and palm rolling every day will help your dreadlocks mature faster. After your dreads mature, they will require less maintenance.
Some scalp irritation or itchiness is normal in the first few weeks after dreading.
Use a metal or dread-specific comb, as regular combs will break and bits of plastic can get caught in your dreads and damage your hair.
You can remove the rubber bands at the scalp after about two months. Remove each band as each individual dread is ready; you don't have to take them all off at the same time. Remove the bands at the tips once hair will remain locked without them; this may take longer than two months.
