By repairing the structural integrity of the hair, not just temporarily repairing bonds, K18 truly renews dry, brittle hair and restores strength, softness, and bounce for hair. It only takes 4 minutes to achieve hair that looks and feels like it did in its original, undamaged state before bleaching, color, chemical services, and heat. With just one salon treatment, hair is restored to 91% original strength and 94% original elasticity.*
*Results may vary depending on hair type, quality, and history.
