Which hair type is characterized by a tightly curled shaft?

Straight hair
Coily or curly hair
Wavy hair
Fine hair

The correct answer is: Coily or curly hair

The hair type characterized by a tightly curled shaft is coily or curly hair. This hair type typically exhibits a zigzag or corkscrew pattern due to the shape of the hair follicle from which it grows. Coily hair can vary in texture, appearing either fine or coarse, but what distinctly defines it is its curl structure. In contrast, straight hair is known for being smooth and sleek, lacking any curls or waves. Wavy hair lies between straight and curly, exhibiting a gentle wave pattern without the tight curls that define coily hair. Fine hair refers to the thickness of the individual strands rather than their curl pattern, meaning it can be straight, wavy, or even curly but remains distinguishable by its thinness.
