So, I have been using Rogaine for the last 5 months. I never experienced the initial shed (that I noticed). At about 2 months, I noticed a decrease in shedding almost half of what I used to shed on some days. At about 4 months, I noticed a huge improvement in my hair. Aside from seeing a lot of regrowth, my part was significantly tighter. but at 5 months, I noticed my shedding is up again. Not as much as it was pre rogaine, but not as low as month 2. Is this normal? would it go down again?
