Sydney Sweeney’s Hairstylist Shares the Star’s Secret For Shiny, Healthy Hair

A chameleon on and off screen, Sydney Sweeney has proven to be the It girl of the moment. Her chic outfits always garner attention and her blonde locks have essentially become her signature accessory. Earlier this year, the 27-year-old actress became an ambassador for Kérastase, appearing in campaigns for the haircare brand. According to Sweeney’s hairstylist, there’s one much-loved Kérastase product that the Euphoria star uses, and he tells Us it’s the secret to keeping highlighted hair looking healthy, shiny and red carpet-ready.

Glen Oropeza has worked with countless celebrities over the years, prepping their strands for major events, but his Instagram most often features Sweeney. Short and sleek or sultry and long, Oropeza creates effortlessly glam yet unfussy hairstyles for The White Lotus and Anyone But You actress using Kérastase products. The luxe haircare brand was established in Paris in 1964, and the Elixir Ultime Hydrating hair oil is one of its bestselling products. It tames frizz and increases shine, yet does not weigh hair down.

“If I’m using heat tools on Sydney’s hair, I’ll apply 1-2 pumps to her mid-lengths and ends before applying any heat,” Oropeza said about using Elixir Ultime on the star. “It not only protects against up to 450°F but also gives the hair gorgeous shine post-styling.” He adds that he’ll “often use it as a finishing touch on her hair to give it some added shine or to add some texture and separation for a more lived-in look.”

Oropeza points out that Kérastase Elixir Ultime is “an essential” for his job as a hairstylist “because it’s multi-use, lightweight and works for every hair type.”

“Beyond adding extreme shine to any style and protecting hair from heat and humidity, it’s also great for breaking down heavy-duty styling products, or as a treatment for in-between wash days due to its strengthening and hydrating benefits,” he says. “The uses are endless! My clients also love the scent, which is always a plus.”

The fragrance, which shoppers say is lovely without being overpowering, has notes of heliotrope, freesia and sandalwood.

Formulated with camellia oil harvested in France for ultimate hair hydration, Elixir Ultime works to soften and strengthen strands. And Sweeney is not the only one who enjoys using the product — according to the brand, a bottle is sold every minute! From curly gals to those with finer strands, those who use it can’t help but write rave reviews.

“This gives a luxurious feel to the hair and smells amazing!” one happy shopper wrote. “Keeps it moisturized throughout the day and shiny. I’ve tried olaplex, VERB, and Moroccan oil and this is by far the best. I fear it is worth the price. Will repurchase. I have thin hair and the travel bottle will be more than enough for probably a year.”

If you’d like to see what the buzz is about, shop the golden oil starting at $30. Since only a few drops are needed, you could get away with buying the smallest size, which is both travel-friendly and will last a long time. However, if you fall in love, there are also bigger, refillable bottles for year-round shine and healthy hair. Get glowing!
