Schwarzkopf Professional Igora Royal Highlifts 10-14 is a permanent dye that brings you High Definition coloring with uncompromising gray hair coverage and optimal retention. It is advisable to mix the dye with the oxidant (sold separately) in a proportion of 1 + 1 (60 ml of dye with 60 ml of 20% Vol oxidizer) in a non-metallic bowl. Apply the dye: divide the hair by making the part in the middle until reaching the nape of the neck and apply the product from the root using the brush. Then, start sectioning in the same way you did before, to apply the product little by little all over the hair. Once the impregnation is all over the hair, we will massage the entire hair with the gloves and leave for 30 to 45 minutes of exposure. If you want to stain only the root, apply to the desired area. Once the exposure time is over, wash with plenty of cold or lukewarm water until the water runs clear and stops "spitting out" the hair dye. Apply shampoo. Store in a cool, dry place.
