Lisin symptoms and conditions

I was on Diovan HCTZ for a number of years for my high blood pressure. It worked pretty well, keeping my b/p to around 130/80, it had been 158/90. The Diovan, since no generic is available, is expensive but I did have a prescription plan at the time. I recently retired and asked my doctor to switch me over to a generic medication to cut my cost. He put me on lisinopril hctz 20/12.5mg. I took it once a day and had great results with lowering my blood pressure. No side effects until the third month, I then began to notice a great deal of hair loss. Since I am 58, 15 years post menopausal, dye my hair, I thought maybe it was the dye (unusual since I have been using the same product for years). I started washing my hair every other day instead of daily. This did not help, I still had to vacumm my bathroom floor daily. At this point I looked up on the internet and found this site about the connection of lisinopril and hair loss. Being an RN I decided to cut the pills in half for a week and see what happened. Sure enough, my hair loss stopped. I then went to my doctor equipt with this information. I am now on HCTZ 25mg daily and taking my blood pressure 2x/day. My b/p stays around 140/80. I know I have to go back to the doctor next week to discuss what to do next because this is not working. Luckily I HAD very thick hair otherwise I would be bald. Does the hair grow back? Does anyone have any other medication they can suggest that does not have this side effect? Too bad, I was doing so good on the lisinopril with my b/p and it did not make me tired like the diovan did.
