No, you cannot feel your hair growing. This is because the growth process happens at the root of the hair follicle, which is located beneath the skin's surface.
Here's a breakdown of why:
- Hair growth occurs within the follicle: The hair follicle is a tiny sac embedded in the skin. It contains the hair root, which is responsible for producing new hair cells.
- Growth happens at the root: The hair root is where the hair shaft is formed, and it's constantly dividing and pushing older cells upward.
- No sensory nerves in the follicle: The hair follicle itself lacks sensory nerves that could transmit the feeling of growth to your brain.
- Sensory nerves are in the skin: The sensations you feel from your hair, like touching or pulling, are detected by sensory nerves located in the skin, not the follicle.
Therefore, while you can feel your hair when it's touched, you cannot feel it growing because the growth process happens beneath the skin's surface.
