Meet "4D Hair Colour": The Futuristic Technique L.A. Girls Are Going Crazy Over
When I ask you to picture the classic L.A. hair colour, what comes to mind? A bright yellow Playboy blond? A shadowy ombré? An icy platinum? There's a lot of hair colour happening in this dreamy city—some of it more pinnable than the rest—but one savvy Beverly Hills colourist says there's a futuristic new trend that's about to take over your social media feeds, the red carpet, and eventually make its way across the Pacific (you heard it here first).
The scoop comes from Matt Rez, a colourist at Meche Salon, who's responsible for the double tap–worthy highlights we see on Chiara Ferragni, Lea Michelle, and many other celebs. According to Rez, the future of hair colour involves an innovative new technique that guarantees the perfect, most flattering blonde, red, or brunette for every client. He's intriguingly named it 4D Hair Colour, and get ready, people; it's going to be the new balayage.
Rez gave us the exclusive on this spellbinding new methodology. Keep scrolling to get acquainted with 4D Hair Colour, the beauty trend that's about to rule salons.
What does 4D Hair Colour stand for? It's "the four elements of contrast that create dimension," says Rez. At first, this concept sounds like something out of Interstellar, but would you expect anything less from the blonde of the future?
See, the problem with most dye jobs you find today, Rez explains, is that they're almost always missing one of the four dimensions necessary for a beautiful, flattering colour. (In other words, they're merely 3D, instead of 4D.) "There's a lot of beautiful hair colour out there. I see it all the time," Rez says. "I see really nice tones, highlights, lowlights, but it's always missing one of the four elements. And the hair colour can't be perfect unless it has all four."
These dimensions, in order, go as follows:
1. Level: How light or dark you want the hair to appear.
2. Tone: The colour direction—warm or cool?
3. Horizontal colour: The gradation of shadowed root to light ends.
4. Vertical colour: A neutral base that aligns with both the highlights and lowlights.
Rez perfected his signature 4D technique in response to the common hair colour mistakes he's seen so much of. For example: "Some people have the perfect level of blonde, but they're missing the warmth, or the lowlights to pop the blonde." Lifting the base colour too light is another of the most popular errors Rez sees, as is creating a colour that's "cool on cool." (We know you've seen those ashy, lifeless blondes.) "For perfect colour, you have to have a neutral, which is your natural base, a warmer colour, which is your mid-tone or lowlight, and your highlight, which is the lightest," Rez explains. But these shades won't be the same on everyone—at least they shouldn't be. The goal is to have a harmonious blend that flatters your natural base colour, your skin tone, and your personality.
Understanding the 4D concept is important because it will allow you to communicate exactly what you want to your colourist and walk out with the most personalised blond possible. Rez always makes sure to go over the four elements with his clients, asking them how much lightness and warmth they want and then describing his plans for the horizontal and vertical highlights, so they're all on board with the same vision.

This client had never gotten her hair done professionally before. Rez worked with her to create a stunning 4D blonde that complements her natural base colour perfectly.
Striking the right balance of coolness and warmth was critical in this transformation. As you can see, Rez still incorporated warmth into the final look, instead of cooling it down completely, which made for a natural, sunkissed result.
Here, Rez took a fairly one-dimensional blonde and created more shadow at the root, melting into brighter, cooler pieces for a look that best complements the client's natural hair colour and skin tone.
