K18 FutureIQ is a leave-in scalp serum built around the brand's peptide and protein approach, aimed at age-related thinning, shedding and early grays rather than styling. It is a lightweight pump serum for people already using K18's repair products who want a daily scalp step. Against scalp serums from pharmacy brands it leans on biomimetic peptide science and a premium positioning; against minoxidil-based treatments it makes no drug-level regrowth claim, so it suits those wanting cosmetic support, not a clinical fix.
