Scalp irritation or open wounds is a common contraindication for chemical hair treatments because such conditions can significantly increase the risk of adverse reactions during the treatment process. Chemical hair treatments often involve the application of strong substances that can exacerbate existing skin issues or lead to more severe irritation, burns, or infections. It is crucial for both the health of the scalp and the overall outcome of the treatment to ensure that the scalp is in a healthy condition before proceeding. This minimizes the risk of complications and ensures a safer experience for the client.

In contrast, while dry hair is often a consideration when choosing treatment methods, it is not a contraindication in the same sense as active scalp irritation or wounds. Oily hair and normal hair do not typically pose any barriers or risks that would prevent the application of chemical treatments. Therefore, ensuring a healthy scalp without irritation or wounds is a critical factor in the safe application of chemical hair treatments.
