The thinnest density of hair in the eyebrow is located in which part?

• A. Medial end
• B. Central
• C. Tail
• D. Head

Answer: (C)

Eyebrow hair density changes along the length of the brow, with more hairs clustered toward the inner part and fewer as you move outward. The outer end, or tail, tapers off because there are fewer hair follicles there, giving a lighter, thinner appearance. This natural taper helps create the brow’s shape and balance. So the thinnest density is in the tail, while the medial end and central area are generally denser.
