COSRX Launches First-Ever Haircare Line with Patented Peptide-132 Technology
From Skin to Scalp: The Story Behind the Launch
COSRX has long been trusted by skincare enthusiasts for its commitment to solving complex skin concerns with clinically effective yet low-irritation formulas. Today, as beauty routines evolve, more consumers are recognizing that healthy hair starts with a healthy scalp. Responding to this shift and the growing “skinification of hair” trend – a movement that treats the scalp and hair with the same care, ingredients, and routines once reserved for skincare – COSRX applied its skincare philosophy to scalp and haircare.
As the “Glass Skin” trend evolves into “Glass Hair,” more consumers are seeking that same smooth, polished, and reflective finish—this time for their strands. Trending topics like Glass Hair, Korean Haircare, Hair Botox, and Hair Styling are gaining huge popularity on social media platforms, reflecting the demand for science-driven formulas that deliver visible transformation. COSRX’s new line taps into this shift, offering a Hair Salon at Home experience powered by skincare-grade innovation. It’s where skin expertise meets next-level haircare—rooted in performance, not promises.
The result: a line that nourishes, protects, and restores from root to tip—bringing professional-grade care into the everyday routine. It’s a collection that doesn’t just mask damage but repairs it from within using cutting-edge science.
Meet COSRX’s Haircare Hero: PEPTIDE-132
Just as collagen supports skin, keratin is the essential protein that gives hair its strength, structure, and shine – and it weakens over time due to heat styling, coloring, UV exposure, and stress.
To address this, COSRX’s R&D team developed PEPTIDE-132 (Tripeptide-132 HCl), a patented tripeptide created to target and rebuild damaged keratin. Using advanced 3D laser scanning and molecular modeling, the team designed a molecule small enough to penetrate deep into the hair shaft and bind directly to weakened areas, reinforcing internal structure and smoothing the surface.
Clinically tested and exclusive to COSRX, PEPTIDE-132 has been shown to reduce breakage, improve manageability, and restore bounce, softness, and shine – even after just one use.
“We didn’t want to create just another haircare line. We wanted to take what we know best – skin science – and apply it to the scalp and hair,” said a COSRX spokesperson. “PEPTIDE-132 is the result of over two years of research and development, and it represents our commitment to creating truly functional, transformative products.”
