Using our Virgin Snow Amplified Color is easy. First, make sure to do a patch test on a small area of your skin 24 - 48 hours before full application. If there's no redness or itching, you're good to go. Apply the cream formula evenly to clean, dry hair. For the best results, leave it on for the recommended time according to the shade you choose. After that, rinse it out thoroughly. Remember, this is a semi - permanent color, so it will fade over time. To make it last longer, use a color - safe shampoo and conditioner. Avoid excessive heat styling and prolonged sun exposure as they can cause the color to fade faster. If you notice any signs of irritation during use, stop immediately and consult a professional.
