Top 10 Two Tone Hair Color Advices Before You Go out of the Box

3. The foil method

Another method to create a two-tone effect on your hair is the use of aluminum foil. This method creates chunky and thick color streaks to the top of the head. You can do this by putting hair color inside the foil first and then applying the secondary color on the rest. Basically, the idea is to create a thicker layer of color as you use more foils. It will protect the colors from bleeding to each other. Cover it with a plastic wrap for several minutes and then rinse thoroughly.
