"The best way to describe cold brew hair color is a deep brunette with chocolate red-golden hues," Bargallo said. Another (probably way more foolproof) option is bringing in a picture.

If you're itching for a change, the time to commit to cold brew is now — Bargallo says the cinnamon tones in the hair color make it a perfect option for fall. It also happens to be incredibly low maintenance — if you're already a brunette. "If you keep the roots darker and closer to your natural [color], you can then add babylights to create a soft dimension," he said.
