What does "overlapping" mean in relation to hair weaving with chemical processes?

In the context of hair weaving with chemical processes, "overlapping" refers to the practice of applying a product, such as a chemical relaxer, color, or permanent waving solution, onto hair that has already been treated with a similar product. This action can increase the risk of damage because the previously treated hair is already chemically altered and applying another chemical layer can lead to excessive weakening, breakage, or other forms of hair damage.

When hair strands overlap during the application, areas that have already been processed may not handle the additional chemicals well, potentially resulting in compromised hair health. This is particularly crucial in the salon setting where preserving the integrity of the hair is essential. Consequently, understanding the implications of overlapping is critical for any professional involved in hair weaving or any other chemical processes in order to achieve desired results while minimizing damage to the hair.

The other choices do not accurately capture the meaning of overlapping in this specific context. Distinctly sectioning hair for weaving, applying color gradually, or using multiple processes simultaneously are all important techniques in their own right but do not address the consequences of applying new chemicals over previously treated areas.
