How does hair grow if they are all dead cells?

Hair cells are not dead the roots are alive. The hair grows from the root wich is not dead. once it leaves the scalp the cells are dead. Hair grows because the follicle is alive and produces the hair cells. The part of the hair you do see is dead cells but befor when in the scalp the cells were alive.

Hair grows out of deep pits in your skin called follicles. At the bottom of each follicle is an area, called a bulb, where hair cells are manufactured. As these cells are pushed to your skin's surface, they become hardened and die. The hair that you see on your body is actually a collection of dead cells
