What are the two types of hair texture?

The correct answer identifies the two types that refer to the diameter or density of individual hair strands. Coarse hair is thicker and often feels rougher to the touch, while fine hair is thinner and may feel softer or silkier. This distinction is crucial in cosmetology for determining the appropriate products and techniques for hair care and styling, as the texture influences how hair behaves when cut, styled, and treated.

The other choices focus on different aspects of hair. For example, curly and straight, as well as wavy and straight, refer primarily to the shape and pattern of the hair rather than its texture in terms of thickness. Thick and thin discuss the overall volume of hair rather than the individual strand's texture. Understanding these characteristics is vital for professionals in the field, as they tailor their services based on the specific needs associated with hair texture.
