Hair Strand Width: Understanding Average Size & Variation

The width of a human hair strand varies considerably depending on factors like ethnicity, age, and overall health. However, here's a general range:

* Average: 80 micrometers (µm) or 0.08 millimeters (mm)

* Range: 17 to 181 µm (0.017 to 0.181 mm)

Some sources cite a slightly broader range, such as 50 to 100 micrometers (µm).

Keep in mind that these are averages, and individual hair strands can fall outside these ranges.
