How is hair texture primarily measured?

Hair texture is primarily measured by the diameter of the hair strand. This measurement assesses whether the hair is fine, medium, or coarse. Fine hair has a smaller diameter, making it feel softer and more delicate. Medium hair has a moderate diameter, while coarse hair is thicker and often feels more robust. This distinction is crucial for barbers and stylists to select appropriate products and techniques tailored to different hair types, ensuring the best possible results.

Length, color, and density of hair are important attributes, but they do not define the texture itself. Length refers to how long the strands are, color indicates the pigmentation of the hair, and density refers to how many strands are present on the scalp. None of these factors provide insight into the feel and thickness of individual strands, which is why diameter is the primary measure of hair texture.
