What hair type typically shows more resistance to chemical processes?

Coarse hair typically shows more resistance to chemical processes due to its larger diameter and denser structure. The cuticle layer of coarse hair is often thicker and more tightly bound compared to finer hair types, which makes it less susceptible to penetration by chemical solutions used in treatments such as coloring, perming, or relaxing. This resistance can lead to a longer processing time or the need for stronger formulations to achieve desired results.

Fine hair, on the other hand, has a delicate structure that allows chemicals to penetrate more easily, making it more vulnerable to damage during chemical services. Medium hair, while somewhat balanced, still does not resist chemical processes to the degree that coarse hair does. Wavy hair can vary widely and is influenced by individual characteristics, but it is not inherently more resistant to chemical processes than coarse hair. Thus, coarse hair stands out as the hair type that typically displays greater resistance to chemicals.
