What is the strength of human hair? Are there any factor that influence the strength of determine it? And how?


I do not know the strength of a human hair because there are so many different kinds of humans. Certainly the condition of the hair is a strength determining factor -- is frizzy and or split? What's the diameter of the hair? The thicker it is, the stronger it is.

Do an experiment to find out for yourself. Make a little hair tester by tying a long hair to a little pan into which you can carefully add pennies until the hair breaks. The more pennies supported before the hair breaks, the stronger the hair. Try the experment with hair of different colors -- and be sure to test synthetic wig hair.
