Do nails have roots?

Published in Nail Anatomy 2 mins read

Yes, nails do have roots. The nail root is the area where nail growth begins.

Understanding the Nail Root

The nail root, often hidden under the cuticle, is where the magic of nail growth starts. This area is critical for producing new nail cells. Here's a breakdown:

  • Location: The nail root is situated beneath the skin at the base of the nail.
  • Function: It is the source of new nail cells that continuously push out the older ones.
  • Cell Growth: Cells within the nail root multiply, and as they are pushed forward, they flatten and harden.
  • Keratin Production: These cells produce keratin, a protein that provides the nail with its strength and rigidity.
  • Nail Bed: Once formed, the new nail slides over the nail bed, the flat surface beneath your nail.

How Nail Growth Works

  1. New Cell Generation: The process begins with cell division in the nail root.
  2. Cell Push: New cells push older ones forward.
  3. Keratinization: As they move, cells flatten and harden due to keratin.
  4. Nail Plate Formation: The hardened cells form the visible nail plate.

Comparison with Hair Roots

While nails and hair both grow, their root structures are different.

  • Hair grows from follicles embedded in the scalp.
  • Nails grow from the nail root located at the base under the skin.

Conclusion

The nail root is a crucial structure for nail growth and development. It's not a "root" in the same way as a plant root, but it is the origin point of the nail.
