Have you tried cutting a propecia pill in 4ths? Even every other day with a 4th will help.
Rogaine is just like toppik. It gives you an extra 100 or so hairs per circular inch while you are on it, but you continue to bald at the same rate. And when you get off it, you loose the 100 hairs really fast, putting you where you would have been had you never been on it the whole time.
SODs actually repair damage, I think, and the hair regrown by them should stay around a while even after you get off, them, though it is best to use a little once you regrow what you can, just to maintain it. However, SODs are not strong enough to regrow hair by themself, or even maintain it.
Revivogen blocks 5ar just like propecia, but weaker. Its fatty acid ingredients are as effective on hampster flank organ size as spironolactone is, so I'm guessing it would help your hair as much as spironolactone. However, spironolactone works in a different way, by blocking the receptors where DHT binds, though not that well. If you use them both, you will get a better effect. With the SODs, spironolactone cream, and revivogen, you might be able to do as well as propecia alone, but I don't know. Also, these only work where you apply them. So if your crown is good now and you just put these on the front, you will have a thinning crown later.
Many scams have borage seed oil or minoxidil or saw palmetto. Borage seed oil is good only if its fatty acids are freed from their glycerol, as in Revivogen.
The nizoral is better than nothing, but will not make or break your regimen. People just use it because it attacks from another angle, inflamation I think.
