Which is the thickest strand of human hair?
Individual strands of hair range in thickness from 1/1500 to 1/500 of an inch in diameter, depending on the properties of the hair in question. Typically, blond hair is thinnest since it usually does not have a middle layer like dark hair does. Black hair is the coarsest or thickest.
