K18 Leave-In Molecular Repair Hair Mask
Best intensive repair treatment for chemically damaged hair.
This is the rare treatment that actually delivers on its promise to undo chemical and heat damage rather than just masking it. It requires a bit of patience to apply correctly, but the four-minute wait time is a small price to pay for hair that feels genuinely restored.
