Reply From the Authors: Correction on β-Estradiol Concentration in Hair Growth Study

A user plans to undergo a temporary MtF transformation to regrow hair, using estrogen, RU58841, and Dutasteride, then revert with testosterone. Many users criticize the plan, suggesting alternatives like hair transplants, and emphasize that estrogen is not a reliable solution for hair regrowth.

Various hair growth treatments were discussed, including microneedling, bimatoprost, setipiprant, stemoxydine, PGE2, CB-03-01, WNT Beta-Catenin upregulators, KY19382, topical estrogen, IGF-1, GH, MK-677, oral castor oil, fisetin, resveratrol, cetrizine, and lactic acid. Users shared experiences and sources for these treatments, with some expressing interest in topical solutions and others noting the lack of FDA approval or scientific evidence for certain options.

17-alpha-estradiol may work for hair loss by inhibiting 5-alpha reductase, similar to finasteride. It might lower testosterone in the scalp, reducing DHT conversion.

The conversation discusses using estradiol and its derivatives for hair loss without causing feminization. Users mention alternatives like alfatradiol, topical 17b-Estradiol, and DIM (Diindolylmethane).

Exosomes from mesenchymal stem cells can increase hair growth by enhancing anagen duration and hair shaft thickness through the Wnt/beta-catenin pathway. Phase 2 trials show improved hair counts over 24 weeks.

The user experienced hair loss after adding estradiol (in ALPICORT E) to their finasteride and minoxidil regimen, which initially provided almost full regrowth. The doctor advised using estradiol for 3 months, but users questioned the rationale and suggested sticking with finasteride and minoxidil.
