I've been using Rogaine for almost 2 years now. Once again, in the last couple days my shed, for some reason has picked up dramatically.... once again there are thick streams of hair coming out in the shower. It seems like Rogaine is working, my hair seems like its almost normal again .... then 'bam' my shed picks up and it thins out again. This is the second time this has happened to this degree. I do get mini-sheds but I think this is the second time I've suffered a big shed while on Rogaine (aside from the dread shed). The last one was last summer. Is this something that is normal with Rogaine use? Could it be seasonal?
