Your hair isn’t broken — it’s just misunderstood.
Years of bleach, heat styling, and colour treatments don’t just damage the surface — they break the molecular bonds deep within each strand. That’s where K18’s biotech innovation goes further than traditional conditioners or bond builders.
K18 uses patented biomimetic peptides to reconnect broken keratin chains — reversing years of damage in just 4 minutes. No rinsing, no fluff — just clinically proven results trusted by stylists, salons, and celebrities worldwide.
Explore the full K18 haircare range in the UK, now available at discounted prices. From the iconic Leave-In Molecular Repair Hair Mask to the Detox Shampoo that primes your hair for deeper repair, this collection is powered by science and loved by over 40,000 UK customers — including a fast-growing tribe on TikTok.
