There are particles at the root of the hair. Are they hair follicles? If your hair is pulled out, will it grow back?

It's a hair follicle! Pull it out and it will grow back! Strong hair regeneration ability! Don't worry about getting less and less hair after pulling out! Because there are too many hairs to be sure, you can try another simple example. Sometimes people have hair on their hands or faces. If you pull them out, there will be particles at the roots. After a while, the same position will grow back!
