Are you suggesting throwing all AAs in the trash and just injecting yourself with estrogen? Low dose monotherapy will not stop hair loss, and high doses will have powerful effects. We cis guys are looking for an intermediate option. This implies maximum androgen blockade and minimum estradiol dosages.
I am suggesting you look at the studies. Anecdotally, I have tried this from many different angles and flooding the system with E2 and then using oral minoxidil on top of that is by far the thing that has worked and it has worked impressively. I have been trying to figure out why MtF hair regrowth is so variable and I think it is because we can easily feminize from the neck down with middling levels of T and E2. That's why I say, there is often a reason why a certain approach is not a "thing" among cis-males. I am sure that people have been trying this since 1930, largely without success except for "transsexuals", now mostly called transgender females with SRS. Rob Winter mentions eunuchs treated with estrogen have often regrown copious amounts of hair but that mere castration didn't work to regrow hair.
Furthermore, the body "doesn't care" whether one uses 2mg or 20 mg daily provided that adult female targets are met as those will induce complete feminization.
I am all in favor of you trying different things as that increases our overall knowledge and provides additional anecdotal data points. At the same time, you are not obligated to do research when your goal is more hair. I am just as happy either way but if you read through this massive thread (you need several hours to do so) we have seen people usually meeting success using both an AA and estrogen. I am using MPA but otherwise, I am attempting to show that AA's are not necessary as this is what all of the "cool kids" in the MtF world are doing, called estradiol-only HRT. It definitely works. The other thing that I regret to inform folks of is that sheds even massive ones, seem to be part of the full regeneration process and my feeling already and validated by the article on my thread, is that stopping treatment due to a shed simply sets a person back to zero.
That's why I am recommending people have a hair system or a wig in place as a back-up should a shed happen. I wish I were more sanguine. I was obviously previously but I just never got anywhere on low-dose estradiol in a context where I was not hitting adult female targets. I started wearing two Climara 100's in June, plus 1.25mg of Premarin plus liberal use of estrogel taking me to adult female first trimester pregnancy levels and I posted my test to indicate this--and boom! Profusive hair growth began and then after adding oral min, explosive hair growth commenced. That's when I started regular posting of pics so people could follow along to see if it worked and what it looked like as it came in. The other thing that you might notice is that 2mg at least in the short-run appears to be the minimum used by those with excellent regrowth but most were using above 2mg plus an AA.
Unfortunately the two folks who have written most about this,
@bridgeburn and I, both experienced breast growth far more than is typical of MtF's on HRT so it probably appears that substantial breast growth is often part of this when in fact, it rarely is. But as I quote my favorite line from a forgotten play, "you pays your money and you takes your chances".
Goddess bless.
