Using Kryolan Color Spray 2250 is easy. First, make sure your hair or wig is clean and dry. Hold the spray about 30 cm away from your hair and spray evenly for the best effect. If you have dyed or bleached hair, do a small test on a hidden part of your hair before full application. After use, you can remove the color spray easily with regular shampoo and warm water. Since it's water - soluble, a fixing spray can be used to protect it from sweat. Keep in mind that this product is a flammable aerosol, so store it in a cool place and avoid heating the container. Also, the colors on the chart might be a bit different from the actual product, so don't be too surprised if there's a slight variation.
