    TLDR New compounds show promise as nonsteroidal treatments for hair loss.
    The study investigates bis(trifluoromethyl) phenyl hydroxycinnamate derivatives as nonsteroidal inhibitors of human steroid 5α-reductase type-1 (SRD5A1), an enzyme linked to androgenetic alopecia (AGA). These compounds, synthesized from caffeic and ferulic acids, were tested using in vitro assays and in silico studies, showing promise as alternatives to steroidal inhibitors like finasteride and dutasteride. The derivatives, particularly compound 10a, demonstrated effective SRD5A1 inhibition and maintained high cell viability, suggesting potential as topical treatments for AGA. The study emphasizes the potential of these nonsteroidal inhibitors in treating hair loss by targeting SRD5A1, which is predominantly expressed in hair follicles and contributes to excessive dihydrotestosterone (DHT) production.

      The effectiveness of Dutasteride compared to Finasteride in treating hair loss, with evidence given such as studies and experiences, as well as discussion around whether one should switch from Finasteride to Dutasteride. There is also a discussion on post-Dutasteride syndrome.

      PP405 is a potential hair loss treatment that inhibits mitochondrial pyruvate carriers, increasing lactate dehydrogenase activity and stimulating hair follicle stem cells. In a phase 1 trial, 31% of participants showed over 20% hair density increase with PP405 treatment.

      The conversation is about a 23-year-old who started treating their hair loss with daily oral dutasteride (0.5mg), oral minoxidil (2.5mg), topical RU58841 (80mg), and weekly microneedling at 1.5mm after seeing others' success stories. Significant improvements have been noted, and there is optimism for even better results in the next 6 months.
