Rogaine Foam

[Frank]

I can't tolerate PG in minox solutions so I was on Dr Lee 5% non PG for a few years until he was forced out. Then switched to ************.. same formula then they were forced out. So I just tried the Rogaine Foam and within 10 days had a terrible shed. Especially front and temples. First time it looks like I lost hair. I don't understand the shed because I was already on 5% minox for years. Not sure what to do now. I stopped using it. But have no idea what to try next. Have to do something soon or I'll shed from being off minoxidil after being on it for years.
But the foam shed was scary especially considering the loss in the frontal area which is almost impossible to grow back.

Anyone have any ideas why I would shed like this considering I was already on a minoxidil formula.. a shed in 10 days seems pretty quick.
Any ideas what to try next?

Thanks
