How to use: First, shampoo and dry your hair. 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 colour from roots to ends. Comb through and leave it on for about 15 - 30 minutes, then rinse out and dispose of the remaining mixture. Wash your hands after. Note: Don't use it near your eyes as it may cause blindness. Avoid contact with skin and clothing to prevent staining. Keep it out of reach of children. Some people may have skin irritation, so do a preliminary test before each use. To test, clean a small area of skin behind your ear or on your inner forearm, apply a small amount of the hair colour, and wait for it to dry. If there's no irritation, you're good to go. If you get it in your eyes, flush with water for 15 minutes, remove contact lenses if you're wearing them, and see a doctor. Rinse your hair directly under a faucet, not in the shower, to avoid staining. Maintenance: The colour will fade with each shampoo, lasting 5 - 40 washes depending on your hair type. To reduce staining on surfaces, you can use peroxide - based cleansers, a paste of baking soda and liquid dish soap, or toothpaste on a cloth.
