To solve this, we created a safe, eco-friendly hair dye kit based on polydopamine, a natural dark pigment with excellent body compatibility. Using engineered harmless bacteria as green factories, we biologically produce dopamine from simple amino acids under mild conditions. We also designed a special bio-peptide that acts like glue, helping the natural pigment stick firmly to hair proteins for long-lasting color. Packaged as a practical, easy-to-use kit, our product replaces toxic chemical treatments with a gentle bio-cleansing routine, offering a healthy and commercial solution to graying hair.
