You can do anything with human hair wigs that you can do to your natural hair. This includes dyeing, cutting, heat styling and chemically processing your human hair. Many weave wearers dye wigs to get an exact match to their skin color. Things to remember when dyeing your human hair wigs:
Do a strand test first. Even though you can dye your wigs, you should first test to see how they will handle the coloring process. Mix the dye as directed, then apply to one small strand or section of the hair. Take note of the end result before continuing to dye the rest of the hair.
Experts advise that you don’t attempt to dye non-Remy hair weaves. These wigs have been chemically treated, stripping the strand to its weakest. They are generally not string enough to be dyed.
It may take multiple applications to lighten your wigs. To dye black wigs to blonde or light brown color, you must first strip the hair of its natural color. Then you must bleach the hair to the desired shade. This may more than one try to get to the right color. As usual, do a strand test first to avoid ending up with a head full of orange locks.
Just like strong chemicals can strip and damage your natural hair, harsh chemicals can also damage your human hair wig beyond repair. Remy human hair wigs have the cuticle layer intact. This outer layer of the strand gives the hair its natural shine and body. By using chemical dyes that are too strong for the hair you can strip the cuticle, making your extensions weak, dull and brittle.
