Full Answer

Hair found on different parts of the body, even hairs found on the same person, can vary greatly in size as well as thickness. Temperatures and humidity also affect hair diameter. Warm air causes hair to get thicker. For these reasons, there is no widely accepted value or standard measurement for hair diameter.

  • Q:

    How can someone add inches to their height?

    A:

    While there may be some exercises that can strengthen and stretch the spine, height is largely determined by genetics and is only somewhat controllable by environmental factors such as nutrition. According to 'Scientific American,' only about 20 to 40% of human height is determined by environmental factors, leaving as much as 80% up to genetics, meaning there isn't much one can do to change their height once they stop growing and reach what is known as 'ultimate stature.' While factors such as parental height may give some clue as to a child's growth potential, the Tech Museum of Innovation points out that the genetics of height are complex, with the potential for the involvement of more than 20 genes in determining each individual's ultimate stature, making it hard to determine exactly what contributes to height.
