This is 100% virgin human hair that has not been processed. You can color the hair, however once Virgin Remy hair is treated in any way, it is no longer virgin. Be sure to keep color treated hair conditioned and moisturized. We highly recommend you have a professional stylist color treat your extensions for proper color application, just as they would your own hair. Check our “Haircare” page for some of our favorite products to keep your extensions healthy.
