Hi everybody

Please, if anybody can help me with this question:

When someone pulls on your hair, it can be painful. however, cutting your hair is not. why?

i would appreciate any feed back

thank you

Hair is dead tissue outside the roots, therefore it has no nerve endings in the hair shaft. At the root it has nerve endings.

I appreciate your response so much. thank you for the help.

JentheRN05 is correct. You can say that "hair grows because it's dieing."

As new hair cells divide, it pushes the old cells outward, and the cells die. (Just like skin cells,but with more keratin than than skin cells.)

BTW....cute dog, JentheRN05. :)
