Hair dye works by altering the natural pigments in the hair, specifically melanin, which is responsible for hair color. Permanent dyes penetrate the hair shaft and can break down existing melanin, replacing it with synthetic color molecules. Semi-permanent dyes typically coat the hair rather than penetrating it deeply, affecting the outer layers without significantly altering the melanin. This process can lead to changes in the hair's natural color, texture, and structure over time.
