The Extract of Periplaneta Americana Promotes Hair Regrowth in Mice with Alopecia by Regulating the FOXO/PI3K/AKT Signaling Pathway and Skin Microbiota

Pilose antler extracts may promote hair growth in androgenetic alopecia by activating hair follicle stem cells through the AKT and Wnt pathways. However, results in mice may not directly apply to humans due to differences in genetic and biochemical conditions.

Gut microbiome imbalances can cause scalp inflammation and affect hair follicles, potentially leading to hair loss. Treatments include finasteride, peptides like BPC-157, TB-500, KPV, and lifestyle changes such as diet and exercise.

Pelage Pharmaceuticals' PP405 aims to treat hair loss by reactivating dormant hair follicle stem cells, showing promising results in early trials. The company plans to present their findings at the American Academy of Dermatology Annual Meeting in 2026.

Saw palmetto extract, rosemary oil, microneedling, fluconazole shampoo, and red light therapy helped improve hair thickness and reverse hair loss without using minoxidil or finasteride. The user experienced significant hair regrowth and no longer feels insecure about hair loss.

Excess sebum rich in cholesterol and triglycerides can lead to hair loss through inflammation, with treatments like Ciclopirox shampoo, Benzoyl Peroxide shampoo, and Clindamycin gel recommended for managing conditions like seborrheic dermatitis and folliculitis. Pioglitazone is suggested for Lichen Planopilaris, while Omega-3s and reducing processed foods may improve sebum quality, though genetic factors play a significant role.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.
