B5/Zinc formula...has it worked for anyone????

I had read the thread posted in 2003 about the zinc/B5 formula posted by Chris and just recently tried it. It might be coincidental but it seems my hair looks even thinner in the front now....is it possible to lose hair with this formula?? I would appreciate if anyone has had any experience with this if they could write to me. For the meantime I will postpone using it further..........
