Head doctor symptoms and conditions

Changed the texture of my hair, now it's stiff and breaks constantly. Also falling out- FAST! Most hair is gone. Unable to digest food and pain in right side of head. Doctor won't believe that any of it is from the Lisinopril HCTZ and won't try something else. Have limited ability to pay for medical treatment due to disability and can't seek other medical advice so am stuck with this due to high blood pressure. Any suggestions?
