What is the technical name for hair on the human head?

The technical name for hair on the human head is "capilli." This term specifically refers to the hair that grows from the scalp, distinguishing it from other types of hair on the body. The term originates from Latin, where "capillus" means hair, and "capilli" is the plural form. Understanding this terminology is crucial for professionals in cosmetology and hairstyling, as it allows them to communicate accurately about hairstyles, treatments, and hair health.

The other terms listed refer to different aspects related to hair and skin. "Dermis" is the layer of skin beneath the epidermis that contains connective tissue, hair follicles, and other structures. "Cortex" refers to the middle layer of the hair shaft, which provides strength and color to the hair. "Follicle" refers to the structure in the skin from which hair grows, but it does not denote the hair itself. Thus, "capilli" is the correct technical term for hair on the head specifically.
