If nails and hair are basically dead cells, how come they grow?
I was just thinking about something - if nails and hair are basically dead cells, how come they grow?
That's a great question! Even though nails and hair themselves are made of dead cells, the follicles and nail beds where they originate are actually alive and capable of producing new cells. These new cells push the old ones out, making it seem like the hair and nails are "growing."
