Livin in rainbows
After getting your hair to a pre-lightened state, acquire the colors you wish to be. I would suggest at least 4. Adding different shades within the same color will help give dimension with a more blended outcome, while using completely different colors will result in a more separated and chunky look. I went with the more blended approach - bc I fucking love gradients - and used a variety of Manic Panic and Punky Color oranges, yellows, reds, greens and blues, and a random purple - a total of about 8-10 colors.
Begin with clean, dry hair and a box of gloves. With your lightest color, grab a random section of hair from the top of the head and completely saturate it with color. You want the color to be completely absorbed while still leaving it a bit wet, but not dripping. Twist the hair together to the ends and leave it alone. Do a couple more twists in this color. (it’s okay that it will touch your other, non colored hair - starting with the lightest color means that the other, darker colors will “cover” any uh-oh’s, but the less they touch, the better). Moving to the next color, repeat the steps, twisting the hair together, and putting aside. Repeat these steps with all colors moving slowly down and around the head until all of the hair is separated into individual colored twists. The key to this is randomness.
Leave the color until it has completely dried on the hair - which should only take a couple of hours.The beauty of this is that these colors are completely non damaging to the hair and leaving them on overnight is also acceptable!
Rinse with really fucking cold water until the water runs clear. For this step, I skip shampoo completely, and wait a couple of days until my next wash. It keeps the color longer, and makes it really shiny!
Keep in mind
You are coloring from the top of the crown to the nape (in horizontal layers).
Work in color groups - warm colors (yellow/orange/red/pink) and cool colors (blue/green/purple). When working in your color group, begin with the lightest color in that group, and end with the darkest. This will also allow you to blend the colors, if you want, and also uses less gloves.
Try to avoid putting opposite colors - also called complementary colors (like, red and green) - right next to one another. While the chance is still pretty low, there is a chance of the colors running together and turning brown. This is helpful.
Remember that if you have lightened your hair, a deep conditioner is your very best friend!
