Balding and saggy skin

Ok, somebody out there knows the secret.  What can I do to stop losing hair and get it to grow back.  My DR said that I would start losing hair between 6-9 months out and its still falling out after almost a year.  What is a good  exercise for the upper arms.  I have saggy arms and they look terrible.  I can't go sleeveless even though I have lost 95 lbs.  Help!  Thanks, Nancy

For your hair, first make sure you are getting in enough protein.  After that, I have heard that biotin works well for keeping your hair and getting it to grow back. A good exercise for your upper arms is a triceps extension -- if you google this, you'll probably find pictures that will make it clearer than any description I could give you.  If it's just skin, exercise won't help.
