Styling products symptoms and conditions

Hi, about seven years ago I complained to my doctor of noticing a little thinning at the top of my head. They referred me to a dermatologist who thought it was female hair pattern loss. It was minimal and he said that he rarely saw it get much worse in women. He suggested minoxidil. A year later, I relocated and the doctors at the health clinic noticed my blood pressure was slightly elevated. They put me on HCTZ. I am into healthy organic eating and was disturbed by the need to be on medication. They said HCTZ was a mild diuretic and never mentioned that hair loss is associated with it. After five years on HCTZ my hair loss is severe. I have lost half my hair and it is dry and brittle, no matter what styling products I use. I had long beautiful thick glossy natural hair, but the texture of my hair has totally changed. A few days ago, frustrated by the continual hair loss, I began searching for my own answers. In my first web search, I pulled up many connections to HCTZ and hair loss, including this site. As others have said, I am mad at myself for not taking my health care into my own hands sooner. I have stopped HCTZ and my blood pressure is being controlled by diet, exercise, and drinking plenty of water. What I would like to know-- is HCTZ hair loss reversible? Are there any reputable natural solutions to hair regrowth. (And minoxidil has been disappointing.) Thanks for your comments. They have helped immensely. GG.
