The 15 Hottest Hair Colors That DOMINATED 2017

The color: Dark Roast

Celebrity inspiration: Kendall Jenner

Description: "Kendall's hair is a classic dark brown with cool undertones — it's rich and striking in this photo," said Chelsea Scott, a celebrity colorist and founder of TruHair. "This look can be created with a single-process color in rich dark brown, then using balayage highlights for very subtle dimension." But make sure to book a follow-up appointment every four months: "A clear gloss treatment done monthly helps to keep it rich," Scott said.

Who it works for: "Fair and porcelain complexions look incredibly beautiful with cool, dark hair," noted Scott. "The stark contrast allows the skin to appear porcelain-like. Throw on a red lip and you have perfection — very Audrey Hepburn."
