Propecia in hot countries

[fongsaiyuk]

Hi All,

I have a couple of questions and would be grateful if someone could give me some pointers:

1/ Does Propecia loose its potency in a hot/humid climate? I spent 4 months in Singapore whilst on Propecia, where temperatures would regularly be between 32C-37C, and I didn't think of putting it in the fridge.. By the end of my stay, my thinning had considerably progressed

2/ Does storing Propecia in the fridge affect its potency? I read somewhere there's a risk of condensation, what's the best protection against that?

3/ When I shower and look at hair that fell out, I noticed some of them have a white bulb. Does anyone know why that is? Is that a sure sign it will definitely grow back?
Otherwise is there a way to tell which hair will grow back and those that won't?

Thanks for your time.
