Dermoscopic Features of Pili Annulati: Characteristics of PA

PP405 is ineffective for miniaturized, fibrosed hair follicles in androgenetic alopecia. AMP303 may activate hair follicle stem cells, but minoxidil and finasteride are still the main treatments.

A 27-year-old male with diffuse hair loss, including the donor area, did not respond to finasteride, dutasteride, or minoxidil. He suspects his hair loss may be linked to a mild connective tissue disorder, possibly affecting the structural support of hair follicles, rather than being purely hormonal.

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.

The conversation discusses hair regrowth progress using Minoxidil, finasteride, and RU58841. It highlights the transformation of vellus hairs into terminal hairs in a Norwood 6 frontal area.

Finasteride is effective for DHT/AR-driven hair loss but not for chromosome 20-driven cases, where treatments like minoxidil, prostaglandin analogs, and low-level laser therapy may be more beneficial. Genetic testing can help determine the underlying cause of hair loss to tailor treatment effectively.

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.
