Spectrum-Specific Reds

Rubilane, available this month from L’Oréal Professionnel in both Majirel’s Majirouge and LUO Color, is a new technology that relies on a patented, oxidative hair color molecule to “create a new spectrum of copper reds.” To help you with tech-talk, we e-terviewed L’Oréal R&D’s chemical pros.

Q: What makes the Rubilane molecule unique, chemically speaking?

The dyes used in oxidative hair color are called precursors—primaries and couplers. Generally, the primaries give the color background, while the couplers bring the reflects. Rubilane is a new oxidative primary. This new molecule, with its unique structure, allows the exploration of a new color universe. Upon being released inside the hair fiber, Rubilane exhibits more vibrant colors that equal today’s intense highlight shades, while providing deepness, vibrancy and tenacity. The dye that is the result of the Rubilane/coupler combination, which reflects light within a very narrow chromatic spectrum, shows an almost pristine red-copper reflect. It leads to a deep, vibrant color that’s exclusive to Rubilane.

Q: What makes it longer lasting and allows a broader spectrum of reds?

A: When applied on panelists’ hair in numerous studies, red and copper shades made with Rubilane showed an immediate color result and lastingness (resistance to shampoo) that was significantly better than regular red-copper hair color. Rubilane colors stay more saturated, intense and luminous, shampoo after shampoo.
