The real and short answer... It doesn't! If you are referring to people with cancer losing hair, it is usually the chemotherapy. The radiation treatments often don't even involve x-ray. Has anyone ever met someone who got an xray and lost their hair?

Hair is made up of proteins. Proteins denature (do not function) under high heat, which is what radiation is. Thus, your hair falls out and does not grow.
