    TLDR GLP-1 receptor agonists may increase the risk of a specific type of hair loss called androgenetic alopecia.
    This study analyzed data from 393,596 individuals to explore the link between GLP-1 receptor agonists (GLP-1RAs) and alopecia, finding that those using GLP-1RAs had higher odds of developing androgenetic alopecia (AGA) but not alopecia areata (AA) or telogen effluvium (TE). Specific GLP-1RAs like exenatide, dulaglutide, and liraglutide were linked to increased AGA risk, while semaglutide was associated with AGA but not other types of alopecia. Tirzepatide showed no significant alopecia outcomes. Public interest in the connection between GLP-1RAs and hair loss has risen, as indicated by Google Trends. The study calls for further research and advises clinicians to discuss alopecia risks with patients considering GLP-1RA treatment. Limitations include the inability to isolate patients with pre-existing alopecia and the need for prospective studies.

      UCLA's PP405 shows promise in reactivating dormant hair follicles for hair loss treatment but is still in clinical trials. Minoxidil and finasteride remain common treatments until PP405 becomes available.

      community Female, 30, PCOS diagnosis, MPB Norwood 2. Endo refuses to give anything other than Spironolactone. Feel like I’m at my wit’s end here.

      in Female  53 upvotes 2 years ago
      A 30-year-old female with PCOS and male pattern baldness is frustrated with her endocrinologist's recommendation of only Spironolactone and minoxidil, feeling that dutasteride, finasteride, and progesterone would be more effective. Other users suggest various online sources for treatments, warn against self-medicating due to potential risks, and recommend seeking a specialized endocrinologist or considering additional treatments like Inositol, Berberine, and dermaneedling.

      Dutasteride has been used for 20 years with some hair thickness improvement but no dramatic regrowth. The user also experimented with minoxidil, tretinoin, and peptides like BPC 157 for potential benefits in hair density and quality.
