With the mental state I'm in right now because of balding I would probably give 35 years for it.
I will probably live till around 85 judging by family although I do live way healthier than them. So I would live till 50. Fine with me atleast I get to enjoy the last 25 years.
Is it possible the use any other kind of zinc? I can't find zinc sulfate anywhere in the Netherlands.
EDIT: Ok never mind I found one who ships to the Netherlands. How much do you apply everytime?
Thanks!
