What is the main characteristic of coarse hair?

The main characteristic of coarse hair is that it is more resistant to styling. This resistance comes from the thickness of the hair strand, which typically makes it less susceptible to changes caused by heated styling tools, chemical treatments, or environmental factors. Coarse hair generally has a wider diameter, which contributes to its strength and ability to hold style compared to finer hair strands.

In terms of the other characteristics mentioned, coarse hair does not have thinness; rather, it is the opposite. While moisture retention can vary in different hair types, coarse hair tends to be less prone to damage from mechanical stress due to its thicker cuticle layer, which provides added protection. However, it can also be drier due to its structure sometimes making it less effective in holding moisture compared to finer hair types. This versatility in styling and durability under various conditions is what makes coarse hair distinct in texture and behavior.
