Formulation Deep Dive
K18 Molecular Repair Hair Oil is engineered as a high-performance anhydrous treatment designed to provide molecular-level structural repair and surface refinement. The formulation utilizes a sophisticated carrier system of lightweight esters and alkanes, specifically Caprylyl Caprylate/Caprate, C13-15 Alkane, Undecane, and Tridecane, to ensure rapid absorption and a weightless, non-greasy finish. The active performance is centered on the patented SH-Oligopeptide-78 (K18 Peptide™), which penetrates the hair shaft to reconnect broken polypeptide chains, while Squalane and Persea Gratissima (Avocado) Oil provide essential biomimetic lipids to restore elasticity and moisture. The anhydrous system is naturally stabilized through the use of Tocopherol (Vitamin E) as an antioxidant to prevent lipid oxidation, utilizing Benzyl Alcohol as a part of its preservative and solvent strategy to maintain formula integrity.
