My mother in law is 46 and has too only lost her hair in the radiated area. So she won't lose ALL of her hair, just a little. Compared to the emotions and fear this disease causes, she'll soon find hair loss isn't one of the big issues. However as a woman myself I know how important hair is to us. Just remind her that they do make wigs...my mil has one but won't wear it. Everyone's different though...God bless you and your mother as you start this fight. You'll be in my prayers~
