Hair Treatment 'Wake Up' helps repair and restore limp, dull hair for extreme shine and volume with a light finish (no heaviness!). Natural plant-derived ingredients such as hydrogenated grapeseed, argan oil, squalane, and macadamia nut oil give outstanding luster and moisture retention to the hair. This treatment also contains a special ingredient (y-docosalactone) that encourages hair strands to reinforce and strengthen with heat application (i.e. blow drying). Can also be used as a leave-in treatment. This treatment is part of uka's 14-time award-winning hair care series. Consistent use can lead to results but results may vary. Approximately 97% derived from natural raw materials.
