Here's why:
* Hair is not alive: Hair is actually a dead protein fiber. While the hair follicle (where the hair grows from) is alive, the hair shaft itself is not.
* No blood supply: Once the hair shaft grows out of the follicle, it no longer receives nutrients or blood supply. This means it's essentially a non-living structure.
* No connection to the body: When you cut hair, you're simply severing the shaft. The hair follicle remains intact and continues to produce new hair.
So, while it may seem like you're killing hair when you cut it, it's actually just removing a portion of the dead hair shaft. The hair follicle is still alive and well, ready to grow more hair!
