Alopecia Universalis Following Human Papillomavirus Vaccine Administration: A Case Report

A user with alopecia totalis, borderline universalis, seeks advice on getting into a Xeljanz trial or appealing insurance for coverage. They experienced significant hair regrowth but are now seeing hair loss again and want to try Xeljanz.

PP405 is a promising experimental topical treatment for alopecia that reactivates dormant hair follicles by targeting cellular energy, with large-scale trials planned for 2026. While it shows potential, it cannot regenerate permanently destroyed follicles, making hair transplants the only guaranteed solution for advanced baldness currently.

AMP-303 and AMP-601 are new hair loss treatments targeting dermal papilla cells, with AMP-303 showing early efficacy in transitioning vellus hairs to terminal hairs after one injection. Further clinical trials are planned, and these treatments are seen as promising due to their biologic approach and less frequent application compared to daily treatments.

Male-pattern baldness might increase UVB exposure on the scalp, potentially affecting vitamin D and skeletal health. The hypothesis is debated, with some seeing it as a minor benefit in specific contexts.

Androgenic alopecia (AGA) might have evolved to reduce prostate cancer risk by increasing UV exposure to the scalp, but this theory is debated. Treatments like minoxidil and finasteride are used for AGA, though the exact causes and evolutionary reasons for hair loss are unclear.

Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.
