Question

thickness of human hair is in the range of 0.08 - 0.12​

Answer 1

17 to 181 µm

As a person grows up, their hair becomes thicker and stronger. Another factor is that, the closer to the root of the hair, the thicker a strand of hair would be. In my research, I have found the diameter of human hair to range from 17 to 181 µm (millionths of a meter).
