The problem is that for "average" men, they are proding average amounts of testosterone and larger than normal estrogen levels.
That is different from no or very little testosterone with high estrogen.
Yes, but so what? It still shows that estrogen is good for balding scalp hair.

1) If estrogen is that good then why no studies showing hair recovery?
There are certainly some old European studies which claimed to get beneficial effects for male pattern baldness by using various estrogen solutions topically on men. Those old studies aren't exactly the most carefully carried-out and conducted ones I've ever seen, compared to modern studies like some of the ones with finasteride and minoxidil that used very precise hair-counting and hair-weighing technologies; however, as a group, they _do_ supply some rather convincing arguments that estrogen does indeed help balding.
Since those early days, there have been a couple of studies by Kiesewetter
et al (sp?) that clearly showed with direct
in vitro experiments with biopsied human hair follilces that androgens
suppress the growth of scalp follicles, while estrogen
stimulates their growth. Add to that the long, lengthy, more recent study by that other expert who carefully examined the effects of estrogen on hair (I can't remember his name, but you probably know who I'm talking about), who found the same thing on two different individual patients: the
in vitro addition of estrogen stimulated the growth of their balding hair follicles! Taken as a whole, all this evidence is pretty damned convincing!

2) Why are drugs such as spironolactone such a fail?
What makes you think spironolactone is a "fail"?
