Using Coralline Dream is easy. First, lighten your hair to level 10 blonde if you want the pure light coral color. If your hair is at level 8, you'll get a rose - gold hue. Apply the cream formula as you would with other hair dyes, making sure to cover all the hair evenly. The Amplified formula is semi - permanent and lasts 30% longer than the classic one. Remember, pastels fade faster than vivid shades, so expect some color loss over time. This vegan hair color also conditions your hair as it colors. Before using it for the first time, do a patch test on a small area of your skin. Wait 24 hours and if there's no redness or itching, you're good to go. If you experience any discomfort, stop using the product. To maintain the color, use sulfate - free shampoos and avoid excessive sun exposure, as these can make the color fade quicker.
