Determination of Estrone and 17β-Estradiol in Human Hair by Gas Chromatography–Mass Spectrometry

Finasteride and Nizoral shampoo with Ketoconazole are used for hair loss treatment. Liquid Chromatography–Mass Spectrometry (LC-MS) is recommended over Enzyme-Linked Immunosorbent Assay (ELISA) for more accurate DHT testing.

The conversation is about finding a legitimate online source for 17α-estradiol (Alfatradiol) powder to make a 0.1% solution for hair loss treatment. A user suggests Anagenica as a source.

A user discusses their hormone blood test results before starting finasteride for hair loss, noting high DHT and estradiol levels. They tried topical finasteride for a few days but felt tired.

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).

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 has been using oral minoxidil and dutasteride for hair loss without success and is considering adding topical 17α-estradiol, Pyrilutamide, Clascoterone, or cetirizine. They have confirmed low serum DHT levels and are exploring additional treatments due to genetic sensitivity to DHT and prostaglandin D2.
