Born from Kose's 70+ years of Japanese skincare science, this hair oil was created to solve a modern problem: hair damage from daily styling, environmental stress, and time. The iP Thalasso Repair formula was developed by Kose's research labs to target the cuticle—the hair's outer protective layer—which gets worn down over time. They selected a concentrated blend of 8 marine-derived oils and ceramides, inspired by thalassotherapy, and subjected it to rigorous in-house testing to verify its bonding and repair performance. Manufactured in Japan under strict GMP standards, this 80ml bottle represents a targeted, no-fuss approach to hair repair that has earned consistent praise in its home market for delivering visible results without heaviness or greasy residue.

The Kose Je l'aime iP Thalasso Repair Cuticle Bond Hair Oil (80ml) is formulated with a blend of key ingredients designed to repair and nourish hair. It features squalane, derived from olives or sugarcane, which acts as a lightweight emollient to moisturize and smooth the hair cuticle without greasiness, enhancing shine and manageability. The product includes macadamia nut oil, rich in fatty acids like oleic and palmitoleic acids, to deeply condition and strengthen hair strands, reducing breakage and frizz. Additionally, it contains hydrolyzed keratin, a protein that penetrates the hair shaft to repair damage from heat or chemical treatments, restoring elasticity and resilience. Ceramides are incorporated to reinforce the hair's lipid barrier, locking in moisture and protecting against environmental stressors. The formula also utilizes cyclopentasiloxane, a silicone that provides a smooth, silky finish while improving combability and reducing static. Together, these ingredients work synergistically to repair cuticle bonds, enhance hair health, and deliver a soft, lustrous appearance with long-lasting hydration and protection.
