Ok i actually contacted pfizer about this problem. I have been on rogaine for 1 year almost come november. Saw the intital shedding at first, went thru it, and hair grew a tiny bit. About the last 2 months, my hair has fallen out alot. I mean alot. Pfizer said they never heard of that. Has this happened to anyone if rogaine started working at first but then hair massively shed in a year?
