Is your hair dead or alive?Is your hair dead or alive? Friday, January 26, 2007. Is your hair dead or alive? Many people believe they can do anything to their hair because its dead anyway. Well yes and no. The hair outside of your scalp is psychologically dead, it has no blood, nerves or muscles. When you cut it there is no pain, and it does not bleed. However, for a dead fiber, it is quite remarkable. Healthy hair can be stretched up to 30% of its length, can absorb it own weight in water and can increase its diameter by 20%.
