What does 'overlapping' refer to in hair treatments?

The term 'overlapping' in the context of hair treatments specifically refers to the application of a new product over hair that has already been treated previously, such as where color has been applied before. This can occur during processes like hair coloring or chemical treatments. When a stylist applies new color or treatment over areas that have already been processed, it can create uneven results, potential damage, or unwanted outcomes.

This concept is particularly important for professionals to understand because overlapping can lead to issues such as excessive damage to the hair, especially if the previous treatment has not fully faded. By recognizing the significance of proper application techniques, stylists can maintain the health of the hair and achieve more consistent and desirable results.
