This Month in JAAD Case Reports: October 2023—Central Centrifugal Cicatricial Alopecia in Black Men

Hair loss may be influenced by mechanical tension and inflammation, with the hi-c5 protein amplifying androgen effects, leading to follicle miniaturization. Treatments like finasteride, minoxidil, and scalp massages are suggested to manage hair loss.

Hair loss may be linked to the TRPS1 gene and protein, not just DHT. Amplifica's AMP-303 targets mesenchymal stem cells and shows promise in treating hair loss, unlike Pelage's PP405.

A potential non-invasive topical treatment targeting the WNT Signaling Pathway for hair regeneration is being researched, with positive results on human hair follicle cells. Current effective treatments for hair loss include Minoxidil, finasteride, and hair transplantation.

SCUBE3 and GT20029 are potential treatments for hair loss, with SCUBE3 stimulating hair growth and GT20029 protecting against DHT. A combined approach using SCUBE3, finasteride or dutasteride, and later GT20029 could provide a comprehensive treatment for androgenetic alopecia.

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.

Hair follicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.
