AMERICAN CREW Developer 15Vol 4.5% 500ml

Choose an American Crew Precision Blend shade (Light, Medium Ash, Medium Natural, and Dark) that is compatible with your natural hair color.
Mix the color and the developer in a bowl with a 1:1 ratio. Usually, 20ml is sufficient for hair 2/3 cm long. It is advisable to perform a small allergy test, referring to the product's warnings and ingredients. Choose your preferred American Crew application technique, based on the texture and length of your hair. Each technique can be used with a light, medium, or heavy application of the product to achieve 25%, 50%, 75%, or 100% gray hair coverage. For a more natural look, do not completely cover key areas such as the sideburns and temples. Try to complete the application in less than 4 minutes.
