Evaluation of the Efficacy of Topical Psoralen and Ultraviolet A Photochemotherapy in Alopecia Areata

Exosomes combined with fractional picosecond laser treatment were effective in treating androgenetic alopecia and promoting repigmentation in white hair patches. The role of exosomes in hair repigmentation, particularly in conditions like poliosis, is not well-studied.

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.

The user diagnosed with DUPA tried treatments like dutasteride, finasteride, RU58841, and minoxidil without success and is considering a hair system. They hope for a future cure, possibly with PP405, and others suggest options like scalp biopsy and SMP.

Topical tacrolimus is being considered for androgenetic alopecia, though its effectiveness is unproven. Other treatments mentioned include minoxidil, dutasteride, cyclosporine, and teicoplanin, with discussions on blocking the prolactin receptor for hair growth.

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

The user is using a topical spray with finasteride and minoxidil, red light therapy, and ketoconazole shampoo for hair loss, and is considering waiting a year before getting a hair transplant. Other users suggest microneedling, using oral treatments, and investing in a laser helmet for better results.
