MicroRNAs in the Pathogenesis of Male Pattern Baldness

Microneedling, when combined with finasteride and topical minoxidil, can enhance hair regrowth for male pattern baldness, especially at the temples. Users report varying success with needle depths between 0.5mm and 1.5mm, with stamps preferred over rollers to minimize scalp damage.

Male pattern baldness (MPB) may be influenced by androgen receptors in scalp hair follicles and potentially poor blood flow. Transplanted hair is not immune to DHT, and factors like inflammation and scalp tension might also contribute to hair loss.

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.

Balding scalps have more androgen receptors, leading to increased TGF-beta, which causes blood vessel loss and hair follicle miniaturization. Blocking androgen signaling and TGF-beta may help prevent hair loss.

Male-pattern baldness might increase UVB exposure on the scalp, potentially affecting vitamin D and skeletal health. The hypothesis is debated, with some seeing it as a minor benefit in specific contexts.

Effective treatments for male pattern baldness include finasteride, dutasteride, and oral minoxidil. Non-effective approaches include oils, shampoos, serums, laser therapies, massages, vitamins, and microneedling.
