Topical Supplements:
Nizoral .2% Cream (not shampoo) 1-2 times a day
Bio-Estro Cream 1-2 times a day
Emu Oil 1-2 times a day. Castor Oil and a little Borage Oil or Rosemary Oil
Rub this mixture on once or twice a day depending on your time. Once a day is totally fine and optimal for most. If you can before bed. If not and you must do it in the day. Pick a time where you can leave it on for at least 1-2 hours then shower out if need.
If you suppress the immune system doesn't that mean you can die from a common cold..? I'm pretty sure that's what happens to people who have organ transplants, but i'd imagine they would be on a cocktail of immunosuppressant drugs.
Look at Star Trek TNG. Even in 2364 they don't have a cure for male pattern baldness lol. That being said just shave the head. Most guys that go that route seem pretty satisfied overall.
