Which is stronger,aldactone,propecia or avodart for thinning hair?
Finasteride worked VERY well for me. (Generic Proscar, in five times the dose per pill at only 9$ per bottle at Wal-mart. MUCH cheap than actual Proscar and many other hair-restoring medicines.) Also, finasteride blocks DHT, which is an androgen, so it can help supplement a normal anti-androgen like spironolactane.
Avodart is known to work a bit better than Propecia for hair loss, though not approved by the FDA for use as such in the US. Balding men especially take it because it works so well.
I have been taking it for about 20 months.. and my hair has gone from extremely thin and bald in spots on top to what you see in my avatar. My hairline is still bad and it didn't help the recession at the temples much, but it did fill in everything else a lot and my hairline has crept downward some.
It does take a couple of years to see the full effect, but if you start taking it, you should see the hair starting to grow back within a few months, and the first year usually has the greatest regrowth.. the second year it slows down until it hits its maximum effectiveness.
It's annoying that you use brand names.
Dutastride is better. (Avodart Brand name)

Medical trials.
0.5mg is normal dosage for dutastride Finrastride provides 75% DHT blocking potential.
Dutastride provides nearer 93% because it irriveribly deactivates both Alpha 5 reductase enzyme isotypes where as Finristride will only deactivate 1 isotype.
Spironolactone blocks the bio-synthesis of Testosersone itself rather than DHT biosynthisis direct not only interfereing with DHT levels but also interfering with the resivour in whitch DHT is formed out of. Thus reducing the level of circulating by several orders especally if combined with one of the other above mentioned drugs. (think 99.8% DHT reduction)

Thus taking Spironolactone and Dutastride together would provide a synergistic extreme level of Androgen inhibition based on the options you've provided.
Be aware such an extreme level of androgen inhibition would cause feminisation so just letting you know if your only goal was preventing hair loss.
