How to use: First, make sure your hair is pre - bleached, clean, and unconditioned. Then, apply the Unicorn Hair colour and massage it into each strand. If you want a more intense and long - lasting colour, leave the dye in for 1 - 2 hours. For a pastel look, wash it out after 30 minutes. Rinse your hair until the water runs clear, and then shampoo and condition as you normally do. Maintenance tips: To make your hair colour last longer, use shampoo for colour - treated hair between colourings. Caution: This product is not for use on the face or around the eyes.
