Hair growth is a continuous process that occurs through the formation of new cells within the hair bulb.
The Hair Growth Process
Here's a breakdown of how hair grows:
- Cell Formation: New cells are constantly generated in the hair bulb, the base of the hair follicle.
- Cell Hardening: These newly formed cells stick together and then harden.
- Hair Strand Formation: A complete hair strand develops from this cluster of hardened cells.
- Upward Movement: Because new hardened cells continuously attach to the base of the hair from below, the hair is pushed out of the skin.
In simpler terms, think of it like building a tower with blocks. New blocks (cells) are constantly added at the bottom, pushing the existing blocks (the hair) upward.
Key Aspects of Hair Growth
| Feature | Description |
|---|---|
| Cell Bulb | The base of the hair follicle where new cells are formed. |
| Hardening | The process where new cells join and become rigid. |
| Upward Push | The mechanism by which the hair is pushed out of the skin due to continuous new cell formation. |
Hair growth is a continuous cycle and this process keeps hair growing longer and longer until it reaches its predetermined length. Understanding how this process works can also inform choices about hair care.
