Mix one part color to two parts developer in a non-metal container. Apply the mixture first near the nape of the neck and other spots where hair is darkest. Then, move on to the rest of the hair except the roots. After the formula has been on your hair for 20 minutes, you can apply color to the roots. Leave the dye in place for another 20 to 25 minutes. Use lukewarm water to rinse your hair. Then, finish with a shampoo. Do not use Satin dye over hair that has been treated with metallic dyes.
