Acquired Hair Fragility in Pili Anulati: Causal Relationship with Androgenetic Alopecia

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.

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

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.

Aminexil/Kopexil may help reduce hair loss by addressing perifollicular fibrosis in androgenetic alopecia, but it lacks the extensive clinical backing of finasteride and minoxidil. Some users find it effective, but availability and cost are issues, especially in the US where it's not FDA-approved.

A 25-year-old male experienced significant hair loss due to telogen effluvium and androgenetic alopecia. He began using finasteride, minoxidil, and vitamins, seeing some regrowth but remains worried about hair density.
