Science in Every Drop:
🔬 K18Peptide™ Technology
The patented biotech molecule that travels deep into the hair cortex to reconnect broken keratin chains—reversing damage caused by coloring, chemical services, and heat styling. The result is stronger, healthier hair that looks and feels renewed from the inside out.
✨ Weightless Botanical Oils & Actives
The Molecular Repair Hair Oil is infused with nourishing natural oils and biotech actives that smooth the cuticle, lock in moisture, and shield hair from oxidative stress and UV rays—without buildup or heaviness.
Together, these two formulas create a synergistic treatment routine: the mask rebuilds the structure, while the oil seals and defends the surface. Real repair meets real protection.
