Keune Activator Semi Color 2 Oz

Keune Semi Color Activator is a precision-engineered cream developer formulated exclusively for use with Keune's Semi Color demi-permanent hair color system, available here in a convenient 2 oz size ideal for single-service salon use or at-home touch-ups. Powered by 2.25% (7.5 volume) hydrogen peroxide, it activates at a low, controlled oxidation level that deposits color without lifting the natural base, making every application gentle on the hair structure. Its cream-based formula — built on an emulsified blend of Cetearyl Alcohol, Ceteareth-6, Steareth-20, and Ceteth-2 — delivers a smooth, creamy consistency that ensures even saturation and thorough blending with the color formula. Tetrasodium Etidronate and Salicylic Acid work within the formula to stabilize the hydrogen peroxide, extending shelf life and maintaining consistent developer performance from the first use to the last. The result is rich, true-to-shade color deposit with enhanced durability, fade resistance, and a healthy-looking finish every time. This activator is the go-to choice for colorists and clients targeting toning, grey blending, shadow roots, regrowth touch-ups, low-lighting, color balance corrections, and tone-on-tone results — all without unwanted lift. How to Use Combine 1 part Keune Semi Color with 2 parts Semi Color Activator (e.g., 1 oz color to 2 oz activator) and mix thoroughly in an applicator bottle, shaker, or color bowl. Apply evenly to hair using a brush or applicator, working section by section for full coverage. Process for approximately 20 minutes, then rinse thoroughly and follow with your preferred Keune care routine. For optimal color fidelity, use only the Keune Semi Color Activator with Keune Semi Color — do not substitute with a generic developer.
