When it comes to hair, we're often told to go lighter when the spring season rolls around. And while we love that seasonal shift, this year we're thinking of turning it on its head and going for something richer and deeper. After all, chestnut colors have taken over all of Pinterest and our favorite celebs. To learn about the varying shades of chestnut hair, we turned to two pros in the hair industry: Jonathan Colombini and Aura Friedman. See our favorite A-list sources of chestnut hair color inspiration ahead.

FAST FACTS

Choosing a Shade: According to Friedman, you can choose a shade of chestnut by using the same principles makeup artists apply. "Look at skin tone, eye color, and eyebrow color—the goal is to enhance your best features and neutralize skin that's red or pink." To decide between richer or darker chestnut, determine your level of desired contrast between your skin and hair color.

Maintenance Level: Colombini notes that chestnut hair maintenance depends on your natural hair color. "If you’re a natural brunette, it'll be very low maintenance, but if you have gray hair, you may have a bit more regular maintenance, depending on the percentage of gray," he says. "If your natural hair color is much lighter than the hair color chosen, it'll be more high-maintenance.

Similar Shades: Brunette, warm brown, cool brown, caramel, honey.
