How is hair characterized when it has a large diameter or width and feels thick?

Hair characterized by a large diameter or width and a thick feel is referred to as coarse texture. Coarse hair has a robust structure, which gives it strength and volume. This type of hair can hold styles well but may also require more moisture due to its density. The thickness is a result of larger hair follicles producing strands that are wider than those found in fine or medium hair textures. Understanding these characteristics is important for choosing the right hair care products and styling techniques, as coarse hair often benefits from heavier moisturizers and oils to maintain hydration and manageability.
