research The central role of fibroblasts in androgenic alopecia: A systematic umbrella review

July 2026 in “Cell Transplantation”

This systematic umbrella review highlights the central role of dermal papilla (DP) fibroblasts in the pathogenesis of androgenic alopecia (AGA). The review synthesizes evidence from 43 articles, revealing that DP cells express high levels of androgen receptor and 5α-reductase type II, which, upon activation by dihydrotestosterone, lead to several detrimental effects: downregulation of Wnt/β-catenin signaling, upregulation of TGF-β/BMP pathway, altered secretion profiles, impaired DP cell aggregation, destruction of hair follicle stem cell activation, and induction of inflammation and fibrosis. These findings underscore the dysfunction of DP cells as a key driver of hair follicle miniaturization in AGA, suggesting that targeting DP cell dysfunction could be a viable therapeutic strategy. Evidence regarding the role of dermal sheath cells as a DP cell reserve remains limited.

The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

community TWIST-1 and the cure: Is it really that easy?

in Research/Science 283 upvotes 4 years ago

TWIST-1 gene's role in hair loss and potential as a treatment target. Inhibiting TWIST-1 may prolong hair growth and reduce hair follicle sensitivity to DHT.

community I am actually regrowing my hairline without minoxidil or finasteride (mechanical stimulation)

128 upvotes 7 years ago

Regrowing hairline without the use of Minoxidil or Finasteride, and instead using mechanical stimulation such as Derma Roller, Nizoral, Zinc Pyrithione, Scalp Massage, Scalp Exercise, Fish Oil and other topical solutions. It is cautioned that there are risks associated with not using medically-prescribed treatments, but it is suggested to consider mechanical stimulation in addition to those prescribed treatments.

community It's crazy how it's 2018 and the only hair loss treatments we have feature undesirable side effects and/or aren't even effective for many people.

132 upvotes 7 years ago

Hair loss treatments, including minoxidil, dermarolling, finasteride, dutasteride, hair transplants, hair systems, and shaving the head. The conversation covers various opinions on these treatments and mentions possible side effects as well as alternatives like wigs, vitamins, and lifestyle changes. The post expresses disappointment that there has been no major breakthrough in the field of hair loss treatments despite decades of research.
