Oxidation dyes frequently suffer from rapid fading, uneven color distribution, or degradation when applied to keratinous structures. Addressing these failure modes ensures long-lasting aesthetic results and uniform coverage across varying fiber porosities.

Pigments applied to keratin fibers often suffer from inadequate surface bonding and wash-fastness. Improving the durability of the color coating prevents premature fading and uneven coverage.

Natural and synthetic dyes often suffer from poor affinity, low intensity, or insufficient brightness when applied to keratinous substrates. Improving color deposition and vibrancy ensures consistent aesthetic results across varying hair types.
