I previously took 3 mg of estradiol in gel form and 2 mg orally; at one point, the gel dosage even reached 4.5 mg. I also took 100 mg of spironolactone, splitting the dose between morning and evening. I don't recall if I took the spironolactone continuously or in alternating months. This was back in 2019–2020. I managed to reverse my Norwood 1.5 hair loss completely. I did develop some breast growth during the process, but it doesn't bother me at all—most men over 40 have that kind of chest. I am 41. Later, in 2020–2021, I continued taking estradiol but without the spironolactone. In 2022, I stopped taking estradiol and experienced a reversal; over time, my hair returned to the Norwood 1.5 stage. I don't remember exactly how long that reversal took. In 2026, I decided to experiment with much lower estradiol dosages. I concluded that it is the estradiol that promotes hair growth. I also became convinced that anti-androgens like spironolactone or cyproterone aren't necessary—nor are finasteride or dutasteride. All that's needed is 1 mg of estradiol gel, plus B vitamins and magnesium to support endogenous progesterone production for inhibiting 5-alpha-reductase.
