Unveiling the Role of Estradiol in the Pathogenesis of Female Pattern Hair Loss

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.

Topical estradiol may help with hair loss but can have systemic effects, like reduced testosterone production. Using estrogen blockers can have negative side effects, such as joint pain and reduced sex drive.

A 22-year-old with high estradiol levels is considering starting finasteride for hair loss. They have an upcoming endocrinologist appointment to discuss whether they should proceed with the treatment.

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.

A 24-year-old male using topical finasteride for hair loss is experiencing thinning despite treatment and has high estrogen levels. He is seeking advice on whether high estrogen could be causing hair loss and how others with high estrogen levels have addressed it.

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.
