i am a student at State University of New York College at Geneseo. i am doing a reseach and it requires me to find out the density of human hair, in terms of kg/m^3.
i know that human hair density might have a range. if you have that stat., please also give me.
thank you very much for your concern.
In the Caucasian, human hair density averages 2.2-2.3 hairs/mm square. In Asians, the density averages approximately 1.6 hairs/mm square and in Africans, is averages apprxomately 1.3 hairs/mm square. In the head of an average male with a hair bearing area of approximately 80 square inch area, the density is approximately 1250 hairs per square inch (rounded) bringing the total count to 100,000.
You must keep in mind that this is center point in a Bell Curve, and standard deviations overlap heavily between the races. The highest densities I have measured were in Caucasians at 4 hairs per mm square and the lowest numbers are not trustworthy because they may reflect diseases or some form of genetic balding.
I am doing a project on accurately determining the rate of hair growth. I need to know the density of a single strand of hair. Anybody know?
