This innovative 30ML sachet delivers an intensive rescue dose and advanced therapy specifically engineered for severely damaged, weak hair compromised by chemical treatments or heat styling. The professional formula relies on a dual-action mechanism: keratin, which reconstructs structural hair fibers and seals damaged gaps to grant a silk-like smoothness, and biotin (Vitamin B7), which penetrates deeply to fortify the core structure and enhance elasticity against future breakage. The true value lies not in a superficial shine, but in a profound structural rehabilitation that restores vibrant health, double the resilience, and ultimate protection against environmental stressors—all packed in a practical, travel-ready design.
