Will I notice any hair regrowth or do I need to continue Rogaine treatment after "shedding" phase?

Hair loss after vitamin deficiency
It takes 6-9 months to correct hair loss from a vitamin deficiency. If you now have shedding from Rogaine, it's going to take another 6-9 months. Of course, if you actually have another reason for your hair loss as well (that was not diagnosed), it's not going to improve.
See a hair specialist if things don't get better. But if it's simply a vitamin deficiency, hair will improve in 6-9 months.
