Traditional hair colorants rely heavily on synthetic compounds like p-phenylenediamine (PPD) and hydrogen peroxide, which can cause scalp irritation and allergic reactions in up to 6% of users. These chemical formulations also raise environmental concerns due to their persistence in wastewater streams and potential toxicity to aquatic ecosystems.

The challenge lies in developing plant-based colorants that can match the performance of synthetic dyes while ensuring stability, scalp safety, and consistent color results across different hair types.

This page brings together solutions from recent research—including ferrous salt stabilization systems, ultrasonic extraction methods for enhanced pigment yield, and dual-agent natural formulations that improve color penetration. These and other approaches focus on creating viable alternatives to synthetic dyes while maintaining color intensity and longevity.
