What happens when you swallow a small piece of hair? Is it safe?

Is it even possible to live in an absolute dust-free clean environment, and all the water you drink is 100 percent clean from any hair or dust... show more Every time i pour water in my cup, one or two small pieces of hair enter the water. I have no idea how to prevent that from happening, i have no idea do other people do it. Is it even possible to live in an absolute dust-free clean environment, and all the water you drink is 100 percent clean from any hair or dust substances? is that even possible?

But anyway, what happens to me when i swallow the tiny hair? Am i safe?
