In individual hair strands, hair texture is determined by what factor?

Hair texture primarily refers to the thickness or diameter of an individual hair strand. This characteristic is what differentiates one person's hair from another in terms of texture; for example, hair can be classified as fine, medium, or coarse based on the diameter of the strands.

Fine hair generally has a smaller diameter, which can give it a softer, silkier feel, while coarse hair has a larger diameter and often feels thicker and might be more resistant to styling. Recognizing the diameter of hair helps cosmetologists choose appropriate products and techniques for cutting, styling, and treating hair, ensuring the best possible results for different hair types.

While factors such as hair color, length, and density play important roles in overall hair characteristics and appearance, they do not directly determine the texture of individual hair strands in the same way that diameter does. Understanding this distinction is crucial for effective hair care and styling in the cosmetology field.
