One hair has grow out of the scalp; it can't be fixed.?

IS THIS TRUE?

yea ,once the hair comes out your head it is dead.so once it is damaged you cant fix it.products like split end mender just mends it for a while you still have to cut it off to repair your hair.so really most of them that claim they can repair your hair is not telling the truth.
