Density refers to the amount of hair follicles per square inch; does not always correspond to which property?

• A. Texture
• B. Color
• C. Length
• D. Curl pattern

Answer: (A)

Density is about how many hair follicles sit in a square inch, which mainly affects how full or thick a hairstyle looks. That fullness isn’t a direct measure of how the hair feels or behaves at the strand level. Texture, by contrast, refers to the diameter and feel of each individual hair strand (fine, medium, or coarse). Because you can have a lot of follicles packed into an area with fine hair, or few follicles with coarse hair, density and texture don’t have a fixed relationship. So density doesn’t reliably indicate texture.

Color, length, and curl pattern are also separate attributes that can vary independently of density. Color depends on melanin content, length on growth cycles, and curl pattern on the shape and angle of the follicles. But none are determined by how densely packed the follicles are, which is why texture is the best choice for what density does not consistently correspond to.
