Which type of hairstyle is typically characterized by tight curls?

The afro hairstyle is distinctively characterized by its tight, voluminous curls that extend outward from the scalp. This unique texture and shape is a significant hallmark of the afro, often celebrated for its natural appearance and cultural significance. The tightly coiled curls create a rounded shape that defines this particular style, making it easily recognizable.

In contrast, wavy hairstyles are known for their gentle, flowing waves, while straight hairstyles lack the curl pattern altogether. Loose curls, on the other hand, feature softer, more relaxed curls that do not exhibit the density or tightness associated with the afro. Therefore, the tight curls that define the afro hairstyle set it apart as the correct choice in this context.
