I used bi-est for about a month, and straight estriol for a month prior, I would say nothing even comes close to what I'm experiencing with straight 17b estradiol, nothing else.
Estriol made my skin nice, and stabilized my hair but did not induce intense regrowth and and a marked improvement in scalp and hair texture the way estradiol has.
However that being said a shed is indicative of starting a new growth cycle, however with estrogen that should basically stop after a point and new growth should come in strongly afterward.
I don't know what keto is whether you're mentioning ketorolac, but I do also use anti-inflammatories, but I use them sparingly as using them constantly deprives your body of the good inflammation necessary to induce hair growth.
If you're getting the dreaded breast area tingling indicative of gyno, what you need to do is start taking magnesium, as it increases excretion of estrogen from your body. This is something I did not learn until very recently and was probably in some way contributing to my reduced natural estrogen over the years.
Also, beta sitosterol will inhibit aromatase which might seem like that's counterintuitive, but what you want is the beneficial effects of site application of estrogen without it overloading you in vivo.
Also consider using betamethasone topical if you have any scalp inflammation as it increases estrogen receptor sensitivity meaning you will require less circulating estrogen to do it's job at the hair follicle receptor level.
