Coarse hair typically requires more hydration due to its structure and porosity. Coarse hair strands are thicker and have a rougher texture, which can create more surface area for moisture to escape. This hair type often has a higher density of cuticle layers, making it more prone to dryness and frizz.

Hydration is essential for coarse hair to maintain its health, shine, and manageability. Without adequate moisture, coarse hair can become brittle and may not hold styles as effectively. Therefore, hydrating products such as leave-in conditioners, oils, and deep conditioning treatments are especially beneficial for this hair type to keep it nourished and less prone to breakage.

Other hair types, like straight, fine, or oily hair, generally have different hydration needs and may not require as much moisture as coarse hair does.
