Styling a synthetic hair needs the knowledge of backcombing where the hair is teased to reach a desired fullness and thickness. You must create volume on the synthetic hair using natural methods as they are fuzzy and fall out easily. There are different hairstyling products such as hairspray, hair and other items that can help to keep the backcombed hair in place.
To backcomb a synthetic hair, first divide one or two inch strand of synthetic hair from rest of the hair. Secure it with the remaining hair using a claw or a butterfly clip. You can also use smaller strands that can make synthetic hair easier to work with and it can also give a better hold. Take a synthetic hair strand about three inches down from roots and lift it away from your scalp. Brush the hair with a small-tooth comb all the way down and drag it up toward the roots half inch at a time. This process will help to create fuzziness and thickness. Now leave your hands through the strand to make it smooth and continue to backcomb the hair repeatedly till it gets the desired thickness. Use the same method on the rest of your head and mist the hair with a hairspray at the roots as well as two or three inches below to hold the shape and volume. Try to backcomb the whole strand of the hair to get the unruly and course hair.
