    chemical in hair dyes that can cause allergic reactions

    Paraphenylenediamine (PPD) is a chemical commonly used in hair dyes to achieve long-lasting color. It is known for its ability to penetrate the hair shaft and provide a natural-looking color, but it can also cause allergic reactions in some individuals, leading to skin irritation or more severe responses.
