The three primary types of hair textures are straight, wavy, and curly. These categories describe the natural pattern of the hair strands and are fundamental in understanding various hair types. Recognizing these textures is crucial for cosmetologists when determining suitable styling techniques, treatments, and product selections.

Straight hair typically lies flat and has a smooth cuticle layer, which often allows for a shiny appearance. Wavy hair forms a slight "S" shape and can vary in the degree of wave, influencing how it behaves with humidity and styling products. Curly hair tends to form tighter curls or spirals and can come with varying degrees of volume and texture.

The other options focus on different characteristics or classifications. Smooth, rough, and frizzy pertain more to the condition or behavior of the hair rather than its inherent texture. Fine, medium, and coarse refer to the thickness or diameter of individual hair strands, which is essential for understanding hair density but does not address the pattern of the hair. Lastly, thick, thin, and coarse describe hair density or texture but again don't define the natural wave or curl pattern that is foundational to understanding hair types.
