Keune Semi Color 6.66RI Demi-Permanent Color Dark Infinity Red Blonde 2 Oz

Keune Semi Color 6.66RI Dark Infinity Red Blonde is a salon-quality, ammonia-free demi-permanent hair color in a rich level 6 dark blonde base loaded with double-dose red pigment, available in a 2 oz tube. At the heart of the formula is Keune's exclusive Silsoft Technology, which works on the hair fiber's surface to align cuticle layers and deliver a certified shine boost of up to 67% compared to untreated hair, while simultaneously deepening conditioning and leaving strands silky smooth. The Red Infinity (RI) pigment system sets this shade apart from standard demi-permanents: its oxidative red pigment binds more efficiently to the hair structure, giving the color exceptional durability and fade resistance that outlasts conventional red demi-permanent shades. A dual-action Nourishing Complex features Cocamide infused with Sea Silk, a potent extract derived from red algae, that repairs damaged hair fibers and increases hydration, resulting in up to 55% more smoothness compared to untreated hair. The formula's Soothing Complex combines plant-derived Boswellia Serrata Gum and Bisabolol to reduce scalp inflammation and calm sensitivity during the service. Built on a coconut oil-enriched gel-cream base that is completely vegan, gluten-free, and ammonia-free, the formula mixes effortlessly in a bowl, shaker, or applicator bottle without scalp staining, and processes in as little as 20 minutes. This shade is ideal for professional colorists and advanced at-home users looking to intensify existing dark blonde bases, achieve tone-on-tone depth, or deliver up to 70% grey coverage on natural and Red Infinity shades. How to Use Always perform a sensitivity test 48 hours before application. Mix 60ml (2 oz) of Semi Color 6.66RI with 120ml of Semi Color Activator in a 1:2 ratio (use Semi Color Activator Red to achieve up to 1 level of lift); mix thoroughly in a bowl, shaker, or applicator bottle and apply to clean, towel-dried hair on levels 1 through 10. Allow to process for a maximum of 20 minutes, then emulsify with water, rinse thoroughly, and follow with Keune Tinta After Color Shampoo and Balsam.
