The term that describes the amount of hair present in one square centimeter is known as hair density. Hair density specifically quantifies how many individual hair strands are located within a specific area, typically measured in square centimeters. This measurement is crucial in various hair and scalp assessments, particularly in fields such as electrolysis and laser hair removal, where understanding the density can help professionals formulate effective treatment plans.

Hair volume, on the other hand, usually refers to the overall fullness or thickness of hair rather than the number of strands in a given area. Follicle count can sometimes refer to the total number of hair follicles on the scalp or a specific area but doesn't provide a measurement per unit area like hair density does. Hair mass typically refers to the weight or bulk of hair, which doesn't convey information about the density of hair in a specific area. Therefore, hair density is the most precise term for describing the hair present in a defined space.
