Double R Radiance & Repair Mask combines the power of two high-performance masks to restore hair’s radiance and revitalize the hair fiber in an original Guerlain double tube. This technical feat allows the two opposing sensory qualities of honey and oil to merge perfectly on application, combining the repairing properties of honey with the illuminating strength of a floral oil. Day after day, the scalp is strengthened, and the hair fiber is nourished and lastingly revitalized for shinier, stronger hair. The exclusive double texture developed by the Guerlain art of formulation is made up of 95% naturally-derived ingredients.
