Our one-time color-matching spray (light brown) is carefully formulated with hydroxyethyl cellulose and rehmannia root extract. It is specially designed to effectively help temporarily cover color differences at the hair roots. The application method is extremely convenient: shake well before use and apply it to the roots of dry hair. Keep a distance of about 10 centimeters from the hair roots when using. Spray a small amount in small areas. Do not spray over the entire head or in one area for a long time to avoid dripping the liquid onto clothes. It also helps blend the colors at the hair roots, making the hairstyle more uniform.
