I looked into this too! From what I understand, Olaplex focuses on repairing bonds, while K18 goes deeper by reconnecting keratin chains inside the strands. They’re different approaches, but both are great for damage—it just depends on what your hair needs.Is it just me, or does the science behind K18 sound fascinating? Repairing keratin chains at a molecular level? I have no idea how that works, but I’m intrigued. Does anyone know if it’s similar to what Olaplex does, or is it something totally different?
