You've Never Seen Rainbow Hair Look This Chic Before

Inspired by how light plays off glossy strands, this dye technique calls for a subtle "belt" of color applied around the entire head, making it appear like you're always surrounded by sunlight. Though colorists may recognize this as being similar to the "shine band" trend from the '90s, know that this is a more modern take.

"This band can be placed at different points on the hair, depending on hair length, and can be used to highlight the best features on someone's face," explained Black. "With the illusion of light always hitting the hair at a flattering angle, it also helps to make the hair look super shiny."

At the salon, your colorist will figure out the best section of your mane on which to create the belt, taking your hair's length and texture as well as your facial features into consideration. Then he'll section out chunky pieces and gently lift the halo portion's shade about two levels for an understated look.

"Usually the belt will last two to three haircuts before it needs redoing," Black shared. Remember, the belt is designed around your bone structure, and the color pattern will shift as your hair grows, making it necessary to revise every few months. To keep your dye as fresh as possible, Black suggested using Aveda Color Conserve Shampoo ($21) and Conditioner ($21) for home maintenance.

"[This look is] inspired by fractal geometry [and] how shapes can keep repeating themselves and create something new," stated Black. Love this look? Don't try it at home unless you're a major hair expert. The fractal shard technique utilizes eight interlocking diamond-shaped sections, resulting in a complex colorblocked appearance.

"The diamonds are placed in such a way that when the hair moves, different colors are revealed," said Black. "[Each section is] designed in shape to blend one color into another to create a multifaceted look." As your dye fades, you can visit the salon and have them tone the hues or tweak them, completely transforming the finished effect.

While this flashy maroon mane may be a little edgy for you, the same colorblocking dye technique can be used on shades like brunette and blonde — it's all about providing dimension to your strands. "This technique is designed to layer three colors on top of each other through the hair, creating a unique look that shows all three," clarified Black.

Though this art-deco-inspired look seems intricate, it's actually quite simple and quick for a colorist to achieve at a salon. Black recommended that the hair be sectioned into three blocks. "Each one [should be] smaller than the last, and each one is colored a different color to layer the colors on top of one another," he said.

Should you choose to re-create this technique with vibrant shades, avoid frequent shampoos, which will fade your color faster. "Aveda Dry Shampoo ($26) will freshen up your hair without the worries of vibrancy lost from your hair," Black added.
