"Bryce Dallas Howard does my perfect fall red -- so warm and rich," says Cunningham. "A pop of chestnut in the hair creates a smoldering red that really radiates into the fall and winter season."

Fall hair color means drama -- and what's more dramatic than superheroine-esque, blue-black hair?

"There's nothing prettier or more on-point for the season than raven, blue-black color," says Nawrot. All you have to do to achieve this hue is add, well, blue. Depending on how warm your current hair color is, you can cool it down with blue-tinged color-enhancing products, or get your hair professionally toned or colored.

Once your color is on-point, keep it looking shiny and multidimensional with gloss treatments. "Clear gloss will bring back a lot of the shine you may have lost in summer," says Chaplin.

Rihanna has worn seemingly every hair color on the spectrum, but in this cool black, she looks prettier and more polished than ever.

An all-over glaze or dye isn't the only way to work blue into black hair; Potempa suggests adding a "fun color" -- like steel blue -- to the ends of hair for a supernatural, ombré effect. "Ask your stylist to lighten the ends of your hair to the extreme and then tone them with your favorite blue hue," she recommends. Kylie Jenner models a more literal version of the blue-black trend with midnight blue hair.
