Deep wavy Indian hair combines the characteristics of wavy hair with a thicker strand diameter, making the hair feel fuller and denser. The term "coarse" refers to the texture of the hair strand itself, which is wider or thicker compared to fine or medium textures. Coarse wavy hair has a more pronounced wave pattern and offers significant volume and body. Despite its thickness, it can be quite manageable and versatile, capable of holding styles well. However, it may require more moisture to maintain its health and sheen compared to finer hair textures.
