A cause of scalp irritation after a chemical service can indeed be an allergic reaction to a product. Chemical services, such as hair coloring or perming, often involve the use of strong formulations that contain various chemicals. When these chemicals come into contact with the scalp, they can sometimes trigger an allergic response in sensitive individuals. This can manifest as redness, itching, swelling, or even blistering on the scalp.

In this context, allergic reactions are particularly concerning because they can occur even if the product has been used safely in the past. Because everyone's skin and hair are different, reactions can vary, and identifying whether someone is allergic to a specific ingredient is crucial for preventing irritation after chemical treatments.

While there are factors such as product selection, frequency of washing, and styling techniques that can influence the overall health of the scalp, the direct correlation between chemical services and allergic reactions makes this response particularly relevant for understanding potential causes of discomfort following such services.
