@bridgeburn what's your view on topical estrogen at a not so high dose? Do you still think it would do something good? Even if small?
I am also on oral AA, just not confident risking it with bigger doses of estrogen even if topical...
Also second question: do you still see some shedding from time to time? Or is it 0 now?
I know you asked this earlier, I was going to get to it but since I wasn't online here for awhile and then came here again, Ive needed time to respond to all the replies and PMs and the older ones get priority.
Certainly, i don't think it will hurt. There are studies showing benefit with topical estrogen in women however the article posted earlier said this:
" Due to unwanted side effects like gynecomastia, E2 should not be used in men because very high topical doses seem to be required to obtain measurable hair growth effects "
If you think about it though, women rarely have slick bald temples even if they are thinning, that's less fibrosis. as well as less testosterone to antagonize it.
Also, Look at this for example:
"Although minoxidil is poorly absorbed through the skin, systemic doses in the range of 2.4 to 5.4 mg/day can be anticipated if application is made to entire scalp."

there is a reason min solution is kept at 5%. probably for a decent amount to get through. If you were to drink it, a one month bottle would last 9 to 10 months. the estrogel though is typically .06%
I ver much think though it becomes more helpful when combined with a strong AA. This guy also had used estrogel:
he used pill and gel combined along with high amounts of cyproterone in his regimen.
and we all know that I used it topically, at first with a small amount. but I was on higher AA doses back then and used less systematic estradiol, only rubbing it on my scalp. but even a small amount gave me significant gyno, and it seemed more sides was also more results.
Here are my thoughts on this: Estradiol is beneficial both directly and indirectly.. the direct benefit is the change in gene expression, it upregulates many genes which are downregulated in balding scalp.. So, hormones are small molecules. It has to go into your cells,..
Cell by Cell. which makes sense to me that we need a significant amount. because we have so many cells, and cells themselves multiply.. If you take 1 dose of estradiol. it will affect some cells, but soon the "male cells" will still be continuing division and outnumber the changed cells.. You have to somewhat Outrun the male programmed hair cell division. Like walking up a downward moving escalator. I'm sure there are different tolerances for this.. Some people start balding at puberty, and some suddenly get a receeding hairline at 35 years old.. I don't believe that the 35 year old suddenly got more DHT, I believe that hormones are continuous and gradual and it was slowly changing gene expression since he hit puberty but it didn't show up until it hit a certain threshold which took until 35 for that individual.
Minoxidil for example has made my arms overall more hairy than before HRT but recently and pretty suddenly a big patch has been forming on my right hand, and only my right one. the hormones after about a year and a half probably caught up.
So, the antiandrogens can help with this. blocking further androgen changes so there's less to outrun, less speed to the escalator. although we must also catch up, years of previous exposure which makes the epigenetic locks quite stubborn.
Further more, People likely try to use the estrogel topically to limit the systematic sides. But those systematic levels do alot of good things too, for hair.. Estradiol lowers T production, reduces 5alpha reductase, to a much less than finasteride but still it inhibits it to an extant, increases SHBG (which is lower in bald men), reduces PGD2.
Also second question: do you still see some shedding from time to time? Or is it 0 now?
It is normal, according to google searches, to lose between 50-100 hairs everyday. I have a periods where I lose probably about that normal amount everyday for a for months, and then a few months that I hardly shed very much.. strangely my body hair is totally synchronized. Every few months or so, hundreds of body hairs fall out easily for a few weeks. followed by a few months of re thickening and growing longer. then it repeats.
