Coarse hair is typically the most resistant to chemical treatments due to its larger diameter and more substantial cuticle layer. This structure makes it denser and less porous than other hair types, meaning it does not readily absorb chemical solutions. As a result, coarse hair often requires higher concentrations of products or longer processing times to achieve desired results. This resistance can be an important consideration in hair treatments, as stylists must adjust their techniques accordingly for effective processing without compromising the hair's integrity.

In contrast, fine hair is more susceptible to damage from chemicals because of its thinner structure and higher porosity, allowing for easier absorption of various treatments. Medium hair falls somewhere in between, while textured hair encompasses a variety of curl patterns and can sometimes be resistant but not universally so. Thus, coarse hair stands out as the most resistant type when it comes to chemical processes in the context of barbering and cosmetology.
