Dean, I've been tolerant till now, and I see your pain.
But, your info is blantantly false.
I'd be surprised you got an actual study to back it up.
Go see a doctor to see if your hair loss is androgen related.
No anti-androgen treatment will work if its not what causes the hair loss.
Spiro/Avodart/Finesteride can causes shedding for 4-6 months, but all I've seen is positive experience online for people who rode it out.
Shedding is not a good indicator, a photograph with no flash taken outside is the best evaluation.
A diuritics don't cause hair loss, it actually don't change much in your body, except maybe your electrolyte levels will go down slightly and you'll retain less water. That has no physiological impact if you drink anough water. If you take estrogen, which is the opposite of a diuritic (water retention), you'll actually balance out spiro's effect and stay at your normal weight.
