TLDR SKH1 hairless mice have identifiable epidermal stem cells with specific markers.

The study characterized epidermal stem cells in SKH1 hairless mice, a model for UV-induced carcinogenesis, by identifying stem cell populations using markers such as CD34, α6-integrin, Keratin-15, Gli1, and Sox9. CD34 was uniquely expressed in the hair follicle bulge region, and CD34+/α6-integrin+ cells were isolated using FACS. These cells exhibited stem cell properties, including slow cycling and high proliferative capacity. The analysis confirmed the presence of 0.23% CD34+ and 1.05% CD34+/α6-integrin+ cells in SKH1 mouse skin, supporting the model's relevance for studying skin stem cells despite the hairless phenotype.

community Clearing the air on how non-surgical treatments really work

17 upvotes 6 years ago

Treatments for hair loss, including finasteride, dutasteride, minoxidil, ketoconazole, microneedling, and low level laser light therapy, which aim to reduce DHT production, increase cell absorption and blood flow, and stimulate epidermal stem cells. It also stresses the importance of patience when using these treatments.

community LLLT seems like it's at least a solid maintenance tool. Can also provide ok regrowth in AA and MPB. - Pubmed

16 upvotes 8 years ago

Low-Level Laser Therapy (LLLT) is seen as a safe and effective method for maintaining hair and promoting regrowth in androgenetic alopecia (AGA) and male pattern baldness (MPB), with devices like the HairMax LaserComb® and iRestore helmet being popular. Some users and professionals are skeptical about its long-term effectiveness and cost.

community The Real Cause Of Androgenetic Alopecia

in Research/Science 679 upvotes 1 year ago

Androgenetic alopecia is caused by DHT affecting hair growth. Finasteride and minoxidil are used to manage hair loss by blocking DHT and promoting hair growth.

community A Theory on Why Microneedling Works

170 upvotes 6 years ago

Microneedling may enhance hair regrowth by transferring stem cells to dormant follicles, improving the effects of minoxidil. Users discuss using microneedling with needle lengths around 1.5mm to stimulate hair growth.

community PP405: The Ultimate Hair Loss Drug for Complete Hair Growth

in Research/Science 212 upvotes 1 year ago

PP405 is a new hair loss treatment in phase 2 trials that may promote hair growth by increasing lactate production and activating hair follicle stem cells. It could potentially replace hormone-disrupting treatments like Minoxidil and finasteride.

community The end of balding: We may have just found the secret to hair regrowth

in Technology 680 upvotes 10 months ago

MCL-1 is important for hair follicle stem cell survival, but its impact on human hair regrowth is unclear. Minoxidil and finasteride are the main treatments, with doubts about new discoveries leading to effective human solutions soon.
