Best Hair Dye for Cool Tones 2024

We recently tested L’Oréal Paris Feria’s Multi-Faceted Shimmering Permanent Hair Color, specifically the B61 Downtown Brown (Hi-Lift Cool Brown) pack, to see how its dual-tone formula fares against 2024’s most coveted hair trends. The product promises a subtle, multidimensional shimmer that transitions seamlessly from rich brown to a cooler, more refined undertone-perfect for those seeking a modern, multidimensional look. We applied it to our hair, and the result was a mesmerizing balance of depth and brightness, with the shimmer evoking a sleek, urban vibe. The Hi-Lift Cool Brown added a cool precision that didn’t overpower the base, making it ideal for layering or achieving gradient effects. While the process required careful mixing and application, the payoff was striking: a color that feels both timeless and trend-ready. For a statement that’s neither too bold nor too basic, this pack might just be the hidden gem of the season.
