YES! All of Sisdore’s hair products are made with 100% human hair. They can be permed, dyed or bleached like your own hair. We do not recommend to bleach the natural color hair lighter than #27, please select #613 directly if you want to dye the wig into a light color. Do remember that all of the electric treatments with hair will cause varying degrees of damage. so if you are a begainer for hair coloring/bleaching, please let the professional hairdresser do it to make sure there is no damage to human hair.
