An oily solution which protects the skin by enabling the hair to be dyed without staining the areas around the hair roots (forehead, neck). Its components protect the skin from aggressive chemical processes.
With the fingertips, apply some of the contents of the vial to areas that could become stained (forehead, ears, etc.). Add the rest to the dye with the oxidising agent and mix. Apply the dye in the usual way. Professional use.
Available in 100 ml.
