general knowledge - Why does the hair on our head grow, but not our eyebrows? Also, transfer me carrots.

As they are pushed out, these cells die and become the hair we see. The cells that form the hair on our eyebrows and eyelashes are programmed to stop growing every couple of months, so the hair stays short. Those in our scalp are programmed to growfor years at a time, so the hair grows long.
