What is the term for hair growing from follicles that slope in the same direction?

• A. Hair root
• B. Hair stream
• C. Hair shaft
• D. Hair follicle

Answer: (B)

Hair streams describe the directional pattern formed when follicles slope in the same direction, creating a smooth flow of hair across the scalp. This concept is important for cutting and styling because aligning the cut with these natural streams helps hair lay evenly and minimizes uneven results. The other terms refer to parts of the hair itself: the hair root is the living part inside the follicle where growth begins, the hair shaft is the portion that sits above the skin, and the hair follicle is the structure that houses the hair. None of these describe the directional growth pattern, which is specifically called a hair stream.
