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.
PP405 is not a cure for hair loss but may reactivate dormant hair follicles, similar to minoxidil. It is unlikely to help with miniaturized or vellus hairs and is still in trial phases, with availability expected around 2030.
Treatments for hair loss, including finasteride, dutasteride, minoxidil, ketoconazole, microneedling, and low level laser light therapy, which aim to reduce DHT production, increase cell absorption and blood flow, and stimulate epidermal stem cells. It also stresses the importance of patience when using these treatments.
PP405 is a new hair loss treatment in phase 2 trials that may promote hair growth by increasing lactate production and activating hair follicle stem cells. It could potentially replace hormone-disrupting treatments like Minoxidil and finasteride.
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.
