This study introduces a natural hair-coloring system using size-controlled ink particles (SIPs) from cuttlefish ink and chitosan, addressing concerns about conventional dyes. The SIPs, initially negatively charged, were modified through polyelectrolyte complexation with chitosan to reverse their charge under acidic conditions, allowing effective electrostatic deposition onto hair fibers. The optimal SIP:chitosan weight ratio of 10:1 at pH ~4.7 produced the darkest and most uniform black coloration without using metallic mordants, surpassing the performance of plant-based natural colorants. This marine-biomass-derived method offers a promising alternative for safe and effective hair dyeing.
