Why is it important to know the compatibility of hair products?

Understanding the compatibility of hair products is crucial primarily to avoid damaging the hair or causing adverse reactions. Different products, particularly those containing chemicals like dyes, relaxers, and treatments, can interact with one another in ways that may be harmful. For example, using a clarifying shampoo right before applying a chemical treatment could potentially strip the hair of necessary oils, leading to increased damage during the process.

Additionally, combining incompatible products can lead to skin irritation or allergic reactions in clients, making it essential for barbers to be aware of the ingredients and formulations they are working with. This knowledge helps ensure client safety and satisfaction, as well as the overall health of the hair being treated.
