A Hair Color Hero - Our Argan Oil Permanent Color cream contains advanced micropigments that migrate deep into the hair shaft to deliver true, rich accurate tones. This professional hair color is made with a low-ammonia formula that gives you luminous color, 100% gray coverage, brilliant shine, and unmatched conditioning. All Day Hydration - Argan Oil is rich in essential fatty acids, antioxidants and vitamin E, working to deeply nourish and moisturize hair. This key ingredient is also responsible for strengthening the hair follicle, boosting shine and manageability. Usage Tips - Determine the natural depth or level of hair, as well as the percentage of gray. Choose your desired levels and shades, keeping in mind the mixing ration is 1:2 (1 part color for 2 parts developer). Use 10 volume developer for deposit only or 1 level of lift, 20 volume developer for levels of lift, 30 volume developer for 3 levels of lift and 40 volume developer for 4 levels of lift. How to Use - Section the hair into 4 equal parts for easier application. Take 12 inch sections and apply color starting 12 inches away from the scalp, down to the shaft of the hair. Add color until all 4 sections are completed and process for 15 minutes. Apply the remainder of the color at the scalp area and process for an additional 30 minutes. For gray coverage, process for a total of 45 minutes. Rinse, shampoo and condition using One 'N Only Argan Oil Moisture Repair Shampoo & Conditioner.
