2020 Hair Color Trend: Cinnamon Swirl
One of the new year's biggest hair color trends will remind you of cozy nights curled up by the fireplace with a hot toddy in hand: cinnamon swirl. "Rich auburns have merged into Winter with a luxurious tone-on-tone finish," Papanikolas said. "The best versions have a deep mahogany base color with cinnamon accents."
If you have dark hair to begin with, he recommends keeping the auburn color within two shades of your natural color. "Going any lighter than this can result in brassy tones," he said. Ditto if you have lighter hair but want to go into this ashier territory: stay within two shades. "Any darker can look harsh and inky."
