Hair Highlights: All About Auburn

Since red is an intense color, romantic waves or curls will soften the overall look, says Colette Hagiwara, color director of Yoshi Hair Studio in Beverly Hills. Here, Amy Adams' chestnut locks look downright ethereal.

Known for her eclectic style, Florence Welch might be the poster girl for bold red hair. Skin with warm undertones complements hair in a deeper shade of crimson, says Hagiwara.

The formerly flaxen Jamie King tried out the shade of the moment at the Met Gala. Hagiwara says that although you may want to look like your favorite celeb, it's important to ask your colorist which tone and level of red will best suit your skin tone before making the switch.

Girl next door Isla Fisher has that rare shade of burnt, orange-y red that looks right with both fair skin and a subtly tanned face. With her loose braid and vintage-y lace dress, the overall look is relaxed yet elegant.

Model Karen Elson pulls off a glossy, vibrant shade of red with flying colors. To lock in the shine, use a shampoo and conditioner that is color-safe, says Hagiwara.

Social fixture Jessica Joffe knows how to turn heads. By teaming her soft waves with brick-red lips, she strikes the perfect balance between refined glamour and downtown cool.

A natural blonde, Christina Hendricks has no doubt inspired countless women—famous and not—to give ruby tones a spin.

We're sure that it girl Jessica Chastain has served as inspiration for many a colorist—and client. Her porcelain skin and steel-gray eyes are a color-combo dream come true.
