Koleston Perfect Color Super Mix is a type of hair dye produced by Wella Professionals. The colour comes in vibrant reds, pure naturals, rich naturals, deep browns, special blonde and special mix to suit all your hair colouring needs. Koleston is a professional hair dye and should be used only by someone who has professional experience.
Shake both the Koleston colour and the developer so that the natural oils in both products are thoroughly mixed.
Measure equal parts Koleston with your developer. As a rule of thumb, start with 28ml (1 ounce) of colour for every 28 ml of developer because Koleston colour stops processing after 30 minutes, which is not enough time to dye the hair if you prepare a large amount of dye.
Apply the colour to the hair using a dyeing brush. If the hair has not been previously coloured, apply the colour all over the hair. On previously coloured hair, don't apply the colour to the roots or the last two inches of the hair. Let the dye sit for 10 minutes, and then apply colour to the hair roots and ends.
Cover the hair with a plastic cap and allow the colour to process under a heat source for at least five minutes. Koleston colour takes 30 minutes until it stops developing, so if you use 20 minutes applying the dye, you need to let the dye process under the heat for only an additional 10 minutes.
Rinse all the colour from the hair to finish the dyeing process.
