I have same problem. Tried inositol and NAC and hair & nail formulas for months and nothing has worked. I am getting ready to try this stuff $$ called Hair Rush. In the meantime, i stopped all supplements have begun drinking two cups of Spearmint tea daily and my hairloss has stopped completely over the last few days. Not sure of the specific actions, but Spearmint is supposed to regulate hormones. I'm hoping it's the tea and not just some random coincidence but I've been doing the pull test the last few days and nothing is coming out. If the tea can solve this, I'll return the Hair Rush and just stick with this. I'll update more in a few weeks.

Would like to update everyone since I am the original poster of this thread. I had to stop inositol as it seemed to be messing with my hormones unfortunately. But I had a bunch of lab work done and it turns out I had a few nutritional deficiencies. One of the really low ones was zinc. I read studies that zinc sulfate was pretty good so I began supplementing started with 50 mg day for 3 weeks then dropped it to the RDA of15 mga day. Hair loss stopped and has remained stopped for quite some time now. And finally the patches of visible scalp have started to fill in. So go to your doc and get checked for all deficiencies. Im not saying the low zinc was caused by the B5 but who knows. At this point nobody seems to know much about B5 hair loss. All I can say my problem has been solved.
