Tamoxifen-Induced Total Alopecia

The conversation discusses the mechanism of action of alfatradiol (17 alpha estradiol) in treating hair loss. It explores theories that it either inhibits 5 alpha reductase to prevent T->DHT conversion or aromatizes scalp T into 17-alpha-estradiol to save hair.

The user is experiencing hair loss despite using estradiol, bicalutamide, dutasteride, and topical minoxidil. They stopped minoxidil temporarily, which worsened their condition, and are considering oral minoxidil but are concerned about side effects and cost.

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.

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

A female experiencing hair loss while on testosterone replacement therapy is using oral Minoxidil, Spironolactone, and finasteride, but still losing hair. Suggestions include switching to dutasteride, using topical anti-androgens, and reducing Nizoral shampoo use to prevent scalp dryness.

Finasteride increased testosterone and estrogen, stopped hair loss, and promoted regrowth. Users discussed side effects like libido changes and considered adding minoxidil and aromatase inhibitors.
