How To Apply Semi-Permanent Hair Dye. 

Step 1: Crazy Color works best on hair that has already been pre-lightened. Crazy Color recommends pre-lightening the hair to level 9 or 10 for the most vibrant results.

Step 2: Shampoo and towel dry the hair before applying. Apply your chosen shade, beginning at the roots, and working in sections.

Step 3: Spread the color evenly from the roots, and begin to work it out through to the mid-lengths of the hair.

Step 4: Once the roots to tip of the hair is covered, work the color into each section using your hands. Continue to do this until the product starts to froth slightly, and each section is saturated.

Step 5: Once the application of color is complete, leave for 15-30 minutes depending on the condition of hair. For grey coverage, leave color on for a maximum of 1 hour.
