Coarse hair is generally more resistant to chemical processing due to its thicker diameter and the structure of its individual hair strands. The cuticle of coarse hair is typically more tightly packed and composed of more layers compared to finer hair types. This denser cuticle provides a protective barrier that makes it harder for chemicals to penetrate the hair shaft effectively. As a result, coarse hair may require more time and a stronger formulation during chemical treatments, such as coloring or perming, to achieve the desired results.

In contrast, finer hair often processes more quickly because its cuticle is thinner and less tightly packed, allowing chemicals to penetrate more easily. Medium hair has characteristics that fall between fine and coarse, providing moderate resistance to chemical processing. Wavy hair can vary greatly in texture and thickness, but it doesn’t inherently affect resistance to processing as much as the overall thickness and structure of the hair strands do.
