M-AMINOPHENOL

M-Aminophenol is a chemical compound used as a color developer in hair dyes. It works by reacting with other dye ingredients to create permanent color that bonds to hair strands.
This ingredient acts as an oxidative dye intermediate that helps develop and fix hair color, allowing the dye to penetrate and permanently color the hair shaft.
