Circulating MicroRNA Signatures in Severe Alopecia Areata: Diagnostic Discrimination, Pathway Analysis, and Therapeutic Implications

miR-205, a tiny RNA, can stimulate hair growth by softening aging hair follicle stem cells in mice. Future tests aim to see if this can work in humans.

Hair loss treatments like Minoxidil, finasteride, and potential mRNA therapies are discussed. There is skepticism about targeting specific genes due to the complex genetic nature of hair loss.

A potential breakthrough in hair loss treatment involves softening hair follicle stem cells, but its effectiveness in humans is uncertain. Users express skepticism, noting past successes in mice that haven't translated to human 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.

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 user noticed small circular hairless spots after a buzz cut and has been using finasteride, dutasteride, and oral minoxidil for hair loss. They are experiencing continuous shedding and thinning, and it is suggested they consult a dermatologist for a scalp examination and possible biopsy to determine if it's alopecia areata or androgenetic alopecia.
