What is the average width of a human hair?

Europeans consider hair with a diameter of 0.04 to 0.06 mm as thin, hair with a diameter between 0.06 and 0.08 mm as normal, and hair with a diameter between 0.08 and 0.1 mm as thick. By comparison with European hair, Asian hair is significantly thicker. The average diameter of Asian hair is 0.08 to 0.12 mm.

Is your hair thick?

According to Papanikolas, you can only really test if your hair is fine, medium, or coarse by doing a strand test. If you take a single hair in between your fingers and you don’t feel anything, then you have fine hair. If you can feel the hair, then it’s medium. If you feel a strong, thick strand, then you are coarse.
