What is a contraindication for chemical hair treatments?

Chemical hair treatments can significantly alter the structure and condition of hair, and it is crucial to ensure the scalp and hair are in optimal condition before proceeding. A contraindication is a specific condition or situation that serves as a reason to withhold a certain treatment due to potential harm.

A broken or irritated scalp presents a significant risk when performing chemical hair treatments. The chemicals used in these treatments can cause further irritation, discomfort, or even chemical burns, making the condition worse. Moreover, if the treatment comes into contact with any broken skin, it could lead to infections or exacerbate the irritation. Therefore, it is essential to avoid chemical treatments on any scalp that is not healthy and free from injury or soreness to ensure the safety and well-being of the client.

In contrast, a healthy scalp, moisturized hair, and even oily hair do not necessarily serve as contraindications. A healthy scalp indicates that the skin is intact and free from issues that would complicate the treatment, while moisturized hair is often in better condition to withstand chemical processes. Oily hair, although it may require specific attention during treatments, doesn't inherently prevent the use of chemicals.
