The average human head has between approximately 90,000 and 150,000 hairs. This number varies mainly based on hair color and density:
- Blonde hair: around 150,000 hairs
- Brown hair: about 110,000 hairs
- Black hair: roughly 100,000 hairs
- Red hair: near 90,000 hairs
Hair density, which is the number of hairs per square inch of scalp, typically ranges from 800 to 1,290 hairs per square inch. The total number of hair follicles on the scalp closely matches the number of hairs, averaging about 100,000 follicles per head. Factors such as genetics, age, ethnicity, and gender also influence hair count and density. For example, women tend to have higher hair density than men, while hair density generally decreases with age
. In summary, the typical range is 90,000 to 150,000 hairs on a human head, with blondes having the highest count and redheads the lowest within that range
