How to Color Synthetic Hair

by Traci Joy ; Updated September 28, 2017

The beauty of natural hair is that it is porous, and it will easily accept hair coloring. But what about synthetic hair? Synthetic hair is made of smooth plastic fibers which can not accept the coloring that human hair can. Whether it be because of illness or choice, some people that wear wigs choose wigs made with synthetic hair. Is there a way to change the hair color of these synthetic pieces, or does it need to forever remain the same color? While synthetic hair can not be lightened, there are ways to make the colors darker or richer.

To dramatically change the color of synthetic hair, purchase a liquid fabric dye in your desired color. In one gallon of water, dissolve 4 oz. of dye. Submerge your hair piece in the dye and let it soak for at least 45 minutes. Continue this process until you have reached your desired shade. Rinse well and then take care to condition your hair piece as recommended by the manufacturer.

If you desire a softer change to your synthetic hair piece, a bottle of Roux Fancifull Hair Rinse is a great solution. To evenly distribute the coloring throughout the hair, pour it into a spray bottle. Spray the hair with the Fancifull, but do not rinse. Allow to dry. Re-spray if necessary.

If you desire fun, colorful stripes in your hair piece, use colored Sharpie markers or permanent ink to add the color stripe by stripe. Starting at the root, hold the marker so the wide side of the tip is against the hair shaft. Run along the hair until you have the result you want. This can be a long, slow process, so it is best to plan to do it when you have a lot of free sitting time.


  • The lighter the original synthetic color, the easier it is to dye. If you wish to color your synthetic piece a bright color, starting with a platinum or blond wig is the best way to go.

    After coloring your piece, allow it to dry on something freestanding, such as a paper towel holder, so it touches nothing else and can dry evenly.
