Description
A synthetic colorant commonly used in permanent hair dyes to create dark brown and black shades through oxidative color development. It provides long-lasting, vibrant color results but requires careful handling as it can cause allergic reactions in sensitive individuals. Patch testing is strongly recommended before use, and it should be avoided by those with known sensitivities to hair dye ingredients.
