Emma Stones Sleek Hair Was Thanks to This Anti-Frizz Oil From Roz

Few hair qualms frustrate me like frizz. Equally frustrating? Hair oil that promises to fix flyaways… and, instead, gives hair a greasy look and a weighty, style-flattening feel. I’ve almost given up on hair oil in light of negative past experiences. However, Emma Stone’s laudable, lustrous, and entirely frizzless strands at the 2024 Oscars recently reignited my hope that hair oil can, in fact, work as promised — sans slickness.

Celebrity hair stylist Mara Roszak created Stone’s sleek Oscars style using products from her own line, Roz Hair. After applying a handful of volume-enhancing products from the brand, and heat styling with tools from GHD, Rozak finished Stone’s look with Roz Santa Lucia Styling Oil. The formula fights frizz, enhances shine, and, per the enviable state of Stone’s hair throughout the evening, maintains its silkening effects for hours on end.

You can shop the formula for $45 on the brand’s site, but hurry — once the secret is out, sell-out risk is a not-so-distant possibility.

The Roz Santa Lucia Styling Oil is a lightweight frizz-taming hair treatment. The formula features strand-smoothing ingredients derived from hydrating plant extracts, each of which offers unique benefits for all hair types and textures. Specifically, the formula contains jojoba oil — a highly moisturizing and remarkably lightweight oil known for its smoothing prowess. "Jojoba oil is the perfect treatment oil for dry hair,” dermatologist Dr. Michelle Green, MD, previously told InStyle. Furthermore, Dr. Green noted its featherweight feel, which prevents weigh-down on even the thinnest hair types.

Aloe vera is also present in the formula, where it offers a high-shine, glossy finish. The plant extract enhances luster thanks in part to its hydrating properties. Furthermore, as trichologist Dr. Isfahan Chambers-Harris, Ph.D., previously told InStyle, "Aloe vera works to lower the pH of the hair to the ideal range of 4.5 to 5.5, which helps to seal the cuticles, leaving hair moisturized [and] shiny.” Dermatologist Dr. Jeriel Weitz, MD, also applauded aloe vera in a previous InStyle report, citing its “essential amino and fatty acids, which help to strengthen hair,” plus “minerals such as copper, zinc, calcium, and magnesium,” which further improve hair health.

Finally, Roz’s formula contains argan oil — a hydrating extract known for its smoothing properties and frizz-thwarting power. In addition to adding shine, smoothness, and a generally healthier look and feel, Roz’s hair oil imparts an alluring, subtle scent, composed of vetiver and citron notes for a fragrance that’s equal parts creamy and bright.

For a hair oil worthy of a recent Oscar winner with seriously shiny hair, shop the frizz-fighting Roz Santa lucia Styling Oil for $45.
