does using rogaine foam cause hair growth on your back and arms ancd other bodyparts? seeing as it does get systemicaly absorbed wouldnt this be another side effect.Im pretty sure the makers of rogaine wont tell us the full side effects list.We all think its just scalp irratation but thats a lie in my opinion.Ive heard people gaining weight suddenly while uswing rogaine.I also think it causes hair growth on other body parts.
