Apply most of the mixture to the lengths and the ends of the hair and leave it to develop for 20 minutes, or 10 minutes if you are using a heat source. Then apply the rest of the mixture to the roots, and leave it to develop for 30 to 40 minutes, or 15 to 25 if you are using a heat source. Once the processing time is over, rinse the colour out thoroughly.

Avoid contact with the eyes. If this product gets into the eyes, rinse it out well with clean water.

Wella Welloxon Perfect Developer is for professional use only. It is always important to carry out a patch test before colouring a client's hair.
