@elmechanico, yes many of us have, no luck.
Update: I stopped RU. I was using much less than 1mg per day and the sides eventually came back and are not worth it in my opinion. Going to look for other options.
I am still using Rogain 2x per day but I am still shedding a lot. Going to go back to the dermatologist and have a steroid prescribed for my scalp to help with inflammation, itching, and dandruff that will hopefully slow down the shedding.
Something I have been looking into for years are B12 shots/injections. There are some dermatologists that give them for telogen effluvium and they seem to work well. Might be worth a shot (pun).
