How to use: First, make sure your hair is pre - bleached, clean, and unconditioned. Then, massage the Pony Unicorn Hair Colour into each strand. If you want long - lasting and intense color, leave it in for 1 - 2 hours. For a pastel look, wash it out after 30 minutes. Rinse your hair until the water runs clear, then shampoo and condition as you normally would. Maintenance: To make your hair color last longer, use shampoo for color - treated hair between colorings. Note: This product is not for use on the face, near the eyes, or for dyeing eyelashes and eyebrows as it may harm your eyes. Protect your clothes and workspace before applying it, and wear gloves. Do a patch test first. Use a cotton swab to apply a small amount of the product to your skin (usually on the nape of the neck or near the elbow). Wait 24 hours and watch for any redness or irritation. If you see any, stop using it right away. The product is ready to use; don't mix it with developers, lighteners, or permanent hair colorants. It may temporarily stain your skin and permanently stain fabric. Keep it out of reach of children.
