dead...thats why when you cut your hair it doesnt hurt....hair is made up of dead skin cells.

The 'root' (follicle) of the hair is living tissue. The hair that we see is dead.



That is why it hurts to pull a hair out but does not hurt when it is cut.

Alive at the base, dead when above the dermis!

the root of your hair is alive, thats why your hair continues to grow. however, the shaft of your hair is dead. still, it is covered in proteins, much like the skin of an apple. as the proteins dry out, your hair can split or break off. thats why they say your must "moisturize".



so, the part of you hair that is outside of your head is dead, thats why if it breaks, you dont feel any pain.

The hair follicle is 'fed' by blood cells which make it alive, there are no nerves attached to the hair only at the base of the follicle that is why it doesn't hurt to cut hair. The erectus pili muscles make hair stand on end.

Your hair was never alive to begin with, not even at the follicle. At the follicle hair is produced but it is not alive, as it grows within your tissue is starts to harden. All hair is made up of proteins, it is not made up of living cells nor was it ever. So it can't be dead if it was never alive, it is just hair. And hair doesn't doesn't hurt to be cut because there are no nerve to transmit a signal within the hair. But there are nerve ending around the follicle and that is why it hurts when you pull out your, not because it is a question of whether it is alive or dead. It seems you got poor answers because of the fact that none of the choices you gave were really infact correct. Your follicle produces protein, protein doesn't live, nor does it die.
