Hello, I am a 37 year old user of Levoxyl since February...

Hello, I am a 37 year old user of Levoxyl since February of 2006; thyroid was overactive(Hyperthyroid), received radioactive iodine treatment for that and now my thyroid is underactive(Hypothyroid). My side effects have been severe headaches that last all day and now I am losing my hair by the root. I am starting to get upset about my hair loss. Dr has not answered/responded to why my hair may be falling out. I need to know if anyone else is having this problem and if you have any suggestions as to what I can do to save my hair. I can deal with a headache. Please Help!!!! DZireous@aol.com
