Apply a small amount of paint on your hair and wait for several minutes or use a hair dryer to fix it. Straighten your hair with a hair brush so the paint spread through all the hair. Avoid touching your hair with hands so the color stays natural and elegant. What if it touches my hands of skin? Just rinse it with water, towels, etc. if it drops on the clothes, wash it out with clear water immediately. Do I need to wash my hair in the end of the day? Just put a towel on a pillow or rinse it with water. Moreover, watch out not to contaminate food with the paint. How dense a layer should be? For even applying use a single smear. Though you can repeat as many as you have to, if there is hair uncovered with the paint.
