To use this hair color, first shampoo your hair and dry it. Apply petroleum jelly or baby oil around your hairline and on your ears. Put on rubber gloves and use a tinting brush to evenly apply the color from roots to ends. Comb through and leave it on for about 15 - 30 minutes, then rinse and dispose of the remaining mixture. Wash your hands after. The color will fade with each shampoo and may last 5 - 40 washes, depending on your hair type. Don't use it in the eye area as it can cause blindness. Avoid skin and clothing contact to prevent staining. Keep it out of reach of children. Do a skin test before each use. If it gets in your eyes, flush with water for 15 minutes. For skin contact, rinse with water. If ingested, consult medical personnel. To prevent staining, cover the area when applying and removing. If it stains, you can try peroxide - based cleansers, a paste of baking soda and dish soap, or toothpaste to remove the stains.
