ICYWW, the ever-popular copper hair movement is still a major green flag — and especially for the fall months ahead.

George Papanikolas, a celebrity hair connoisseur and Matrix brand ambassador, says: “This fall follow in the footsteps of icons like Megan Fox by opting for radiant red at your next salon appointment. Red is a great color choice since is can be easily achieved on blonde or virgin hair. If you have previously colored dark hair, then it will need to be stripped to an orange shade first, then the color applied over.” Though of course, keep in mind that the hue needs a good amount of upkeep.

Jennifer Korab, a NJ-based hair guru and salon owner, adds that copper tones are great when you’re looking to add a red and autumnal finish to your hair, and that the fiery shade “matches the fall aesthetic effortlessly.”

“Following the momentum of the Barbie movie this summer, expect to see lots of bright Barbie blondes,” says Justine Marjan, a celeb har guru and Great Lengths brand ambassador.

Sharing a similar sentiment, Papanikolas adds that “Barbie the movie has made its claim to fame not only in the box office but also at the salon.”

Similar to the on-trend coppers of the world, Rachel Bodt, a celebrity colorist and Matrix brand ambassador, says this of cinnamon brown hair: “I’m absolutely loving this color for brunettes. The warm, soft lightness painted on a dark base creates just the perfect amount of warmth without being brassy or too red.”

In the mood for a more edgy, Y2K-influenced vibe this fall? Marjan says that Christina Aguilera’s high-contrast hair in her Dirrty music video is a fun way to bring back the 2000s. “If bleaching and dying your hair is out of the question, this is where Great Lengths extensions can come in handy,” Marjan adds. “You can apply keratin bonds or a few tape-ins to give a pop of color, without the color process or commitment.”

Get the most out of your summertime tan with “gold tones that complement bronzed skin,” says Sunnie Brook, a hairstylist and Biolage brand ambassador.

“Honey blonde color will give you just the right balance for the summer to fall transition,” Korab agrees. “Also try adding a darker root for extra dimension.”

“A little gold makes the hair look super healthy and shiny,” adds Bodt.

You know that low-key shade of “is it blonde or brunette” that so many it-girls, like Hailey Bieber, have been rocking lately? Bodt explains that “baby bronde shows you that you can have playful highlights, without needing to go super blonde.”

While Barbie blonde is technically a more platinum, vivid hue, the *real* Barbie — aka Margot Robbie — rocks a gorgeous, creamy shade of what is referred to as “expensive blonde.” Marjan says this of the color: “Think healthy, shiny, multidimensional blonde.”

“Let’s take some inspo from the changing leaves this fall,” says Cynthia Alvarez, a celebrity hairstylist, groomer, and Biolage brand ambassador. “The goal for this look is for it to feel like you could be a natural redhead [and] is customizable, relying heavily on your skin tone, [and your hair’s] undertone and depth you’re going for. There really is a shade of red for everyone.” As for some tips of upkeep? She adds: “I recommend washing with cold water and using a color-safe system, like Color Last from Biolage.”

Marjan point out that “the added warmth to hair color does wonders for brightening the skin as the weather cools.”

“Following the ‘rich girl’ trends of the summer, warm, healthy looking chocolate browns with lots of shine will be the coveted shade of brown this fall,” explains Marjan.

Korab agrees. “Chocolate brown toned highlights are a perfect way to add subtle but rich dimension to your hair to complete your fall look,” she says. “Whether just a face frame or a full head of highlights, the chocolate brown will elevate your fall hair to new heights.”

As for the exact buzzwords to share with your go-to hairstylist? “This shade of brunette is multidimensional, with notes of caramel and gold throughout to help add sparkle, dimension, and the appearance of fullness to your tresses,” says Alvarez.

Looking for a low-maintenance hair hue that doesn’t require frequent salon visits? “A bronde balayage is the perfect color if you’re a blonde looking to transition into something deeper for fall or if you’re a natural brunette looking to add some dimension to your hair,” Papanikolas shares.

His expert tip? “The key is keeping the highlight tone within four shades of the base color to avoid any harsh lines.” What’s more, the trending color can lean either cool-toned or warm-toned, depending on your preference and skin tone.
