If you’re looking for a brunette that’s anything but basic, the Cold Brew Hair trend is the one to master. This modern technique delivers luminous, iridescent brunettes—and, thanks to our new FUS3™ technology, those cool tones finally last.

What is the Cold Brew Hair Trend?”

Cold Brew Hair is ideal for brunettes seeking luminosity and for blondes ready for a deeper, richer hue. Inspired by the layered tones of iced coffee, this look blends espresso-like depth at the roots with glazed, light-reflecting lengths and illuminated ends. The result is a brunette that feels polished, dimensional, and effortlessly modern—an upgrade for any client wanting to refresh their style.

The Science Behind the Shade: Introducing FUS3™ Technology

FUS3™ is engineered with a patent-pending triple dye network, exclusive to Revlon Professional®. Unlike conventional hair color, which relies on smaller bi-pigment molecules prone to rapid fading and brassiness, FUS3™ utilizes larger, more stable tri-pigment molecules. These pigments interlock and anchor deep within the hair fiber, dramatically increasing color retention and resistance to washout—even in porous or previously colored hair.

By weaving three distinct color molecules together, FUS3™ forms a highly stable chromatic network inside the hair. This advanced architecture not only locks in cool tones for up to 10 weeks* but also delivers richer brown hues, more vibrant and multidimensional cool tones, and deeper overall color intensity. The FUS3™ system actively shields every strand from external aggressors and post-color oxidation, ensuring salon-fresh, sophisticated brunettes that look luminous long after your client leaves the chair. Because FUS3™ is a salon-exclusive, patent-pending technology, it enables you to offer a truly premium service.

Mastering the Cold Brew Hair Technique: A Step-by-Step Guide

The Concept: Deepen, Glaze, and Illuminate

The Cold Brew Hair technique creates a naturalized, multi-layered brunette with dimension and movement. Start by deepening the base— opt for a shade like Color Excel™ Tone-on-Tone 6.81 Dark Brownish Ash Blonde, but any suitable shade from the Cold Brew palette can be used to suit your client’s base and desired depth.

Next, glaze and illuminate the lengths with a lighter tone such as Color Excel™ Tone-on-Tone 9.82 Very Light Brownish Iridescent Blonde , or another shade from the palette, to achieve a sophisticated, seamless blend.

The overall effect is espresso-like depth at the roots, transitioning to glazed, light-catching reflection through the mid-lengths and ends. This approach ensures the finished brunette is modern, dimensional, and entirely personalized—never flat or one-size-fits-all. The flexibility of the Cold Brew palette means each formula can be fully tailored for the client’s skin tone, eye color, and personal style.

Selecting the Right Shades

The Cold Brew palette—drawn from the Marron Glacé Collection—features six new brunette shades available across three color technologies: Revlonissimo Colorsmetique™, Revlonissimo Colorsmetique™ High Coverage, and Color Excel. These carefully selected hues are used to create the multi-dimensional, natural brunette look that defines the Cold Brew technique.

The exact shades in the Cold Brew palette are:

• Revlonissimo Colorsmetique™ Permanent Color:8 Light Brownish
• Revlonissimo Colorsmetique™ 6.8 HC Dark Brownish Blonde (High Coverage)
• Color Excel™ Tone-on-Tone 6.81 Dark Brownish Ash Blonde
• Revlonissimo Colorsmetique™ 7.8 Medium Brownish Blonde
• Revlonissimo Colorsmetique™ High Coverage Color8 HC Light Brownish Blonde (High Coverage)
• Color Excel: Alkaline Technology – Tone-on-Tone Color82 Very Light Brownish Iridescent Blonde

For base depth, reach for permanent shades like 5.8 or 7.8. High coverage options, such as 6.8 HC or 8.8 HC, are ideal for clients needing grey coverage. For the glazing step, tone-on-tone shades like 6.81 or 9.82 deliver a mirror-like, iridescent finish that makes Cold Brew hair pop.

Application Tips for Longevity

Porosity is often where many cool brunettes lose their edge, but FUS3™ is designed to anchor color molecules even in porous hair. Most traditional cool hues struggle to last because their bi-pigment structure simply isn’t stable enough. FUS3™ overcomes this with its advanced tri-pigment network, ensuring pigments stay anchored and vibrant. Each FUS3™ shade delivers richer brown hues, more vibrant cool tones, and deeper color intensity, even with frequent washing.

Traditional pigments tend to wash out quickly, leading to unwanted brassiness that can appear just days after a color service. FUS3™ technology is specially engineered to combat this issue, delaying post-color brassiness and ensuring your clients enjoy salon-fresh, cool results even 10 weeks after their appointment.*

To further enhance client loyalty, consider offering a small token of appreciation when they return for their next color appointment—like a complimentary five-minute head massage. Simple gestures like this create a memorable salon experience and encourage repeat business.

For optimal results, recommend clients wash their hair no more than three times per week with a color safe range to maximize the benefits of this innovative formula.
