Wanting to go from a pink shade to purple strands, or green to blue locks? To change your color without involving bleach or a haircut, we recommend a slow transition starting with hair-healthy fading and choosing a complementary color. Warm shades (pink, red, orange, rose gold) play well together and produce great results. Same with cool colors like (green, blue, purple, teal). Applying a cool shade over a warm color (or vice versa) can produce muddy-looking results.
