Here's why:
* The hair follicle: Hair grows from a structure called a hair follicle, which is located in your skin.
* The hair shaft: The hair shaft is the part of the hair that grows out of the follicle and is visible above your skin.
* Plucking: When you pluck, you pull on the hair shaft, which is strong enough to detach from the hair follicle.
* The root remains: The hair follicle, and the hair root within it, remain in your skin.
This is why hair grows back after plucking. The hair root is still there and able to produce new hair.
