On average, how many individual strands of hair are found on a human head?

• A. 50,000
• B. 100,000
• C. 150,000
• D. 200,000

Answer: (B)

The selection of 100,000 as the average number of individual strands of hair on a human head is based on scientific studies estimating hair density. On average, human beings typically have between 85,000 and 150,000 hair strands, depending on factors such as hair color and genetics. For instance, individuals with blonde hair tend to have a higher density, while those with red hair usually have fewer strands. This average figure of 100,000 serves as a central benchmark within this range, making it a reasonable estimate for educational and testing purposes. Understanding hair density is important in fields such as cosmetology and trichology, where professionals may need to tailor treatments based on hair thickness and volume.
