Static Charge on Hair

If hair loses electrons does it become positively or negatively charged?

Electrons have negative charge, so if a neutral atom loses one, it becomes positively charged.  It now has one more proton (positive) than electrons.

Joke:  Two atoms are walking along, when one says, "I've lost an electron."  The other one says, "Are you sure?" The first, "Yes, I'm positive."
