loose hair and spay; canine thyroid inbalance;

Question
I have a 15 month old mini english bull whose hair falls out very easily.  She doesn't have any particular spot where there is significant hair loss.  It is just all around EVERYWHERE ALL the time.  It wasn't like this before the spadeI noticed it when she got spade when she was 8months old and entering heat.  It has been a serious problem ever since.  We have tried supplements, dinovite, changing food, changing Flea and ticket liquid to a collar.   Is it possible that this is a chemical/hormonal imbalance that can be corrected and if so what are the tests that I should ask my vet to preform?  What kind of medicine should I expect him to give?  
I am at wits end .  My poor dog is confined to my kitchen because of the quantity of hair that comes off of her body on a daily basis.  
Thanks for your help
