Hair density is measured by the number of individual hair strands located on what area of the scalp?

2. 2 square inches

3. Half a square inch

4. 3 square inches

The correct answer is: 1 square inch

Hair density refers to the number of individual hair strands present on a certain area of the scalp. It is typically measured per square inch, which means that the higher the hair density, the more hair strands are present in a specific area. Options B, C, and D are incorrect because they either suggest a larger or smaller area of measurement, which would give an inaccurate representation of hair density. Option A, 1 square inch, is the correct unit of measurement typically used to determine hair density.
