research The Effect of Medications Used in Mesotherapy on Hair Organ Culture and Culture of Dermal Papilla Cells

January 2006 in “Journal of Clinical Dermatology”

Medications used in mesotherapy can affect hair growth and the cells that help hair grow.

research IL-1 alpha inhibits human hair follicle growth and hair fiber production in whole-organ cultures.

30 citations , August 1993 in “PubMed”

This study found that IL-1 alpha inhibits the growth of cultured human hair follicles and hair fibers, suggesting a potential role in inflammatory hair loss conditions like alopecia areata.

research Biphasic Effect of 1,25-Dihydroxyvitamin D3 on Human Hair Follicle Growth and Hair Fiber Production in Whole-Organ Cultures

27 citations , September 1994 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study found that relatively low concentrations of 1,25(OH)2D3 stimulated human hair follicle and fiber growth, while higher concentrations inhibited growth in a whole-organ culture system.

research Fully functional hair follicle organ regeneration using organ-inductive potential stem cells with an accessory mesenchymal cell population in an in vitro culture system

February 2026 in “Biochemical and Biophysical Research Communications”

This study identifies a specific cell population, PDGFRα+/Sca1+/CD34+ mesenchymal cells, which play a crucial role in regenerating hair follicles by promoting the downgrowth phase of the hair cycle, offering insights into organ morphogenesis and stem cell niches essential for adult hair regeneration.

Induction of Hair Growth in Hair Follicle Cells and Organ Cultures Upon Treatment with 30 kHz Frequency Inaudible Sound via Cell Proliferation and Antiapoptotic Effects

research Induction of hair growth in hair follicle cells and organ cultures upon treatment with 30 kHz frequency inaudible sound via cell proliferation and antiapoptotic effects

January 2022 in “Biomedical Reports”

This study suggests that inaudible sound at 30 kHz may promote hair growth and inhibit hair loss signals in human dermal papilla cells, indicating potential as a new treatment for androgenic alopecia.

community New study: Vitamin D counteracts DHT in mice and in human hair organ culture and hair cells

126 upvotes 1 year ago

Vitamin D may counteract DHT and help with hair growth, as seen in mice and human hair cultures. Some users discuss using Vitamin D, magnesium, and other supplements for hair health, while others humorously note the success in mice.

community Weed/THC effects on hair growth/hair loss, and vitality of organ-culture human follicle studies (research review)

4 upvotes 1 year ago

Cannabis and THC may have mixed effects on hair, with some studies suggesting potential negative impacts on hair growth in isolated hair follicles, but these results are hard to apply to living humans. Treatments like minoxidil and finasteride are commonly used for hair loss, and the effects of cannabis might be neutral or vary based on individual factors.

community Riken develops new method for culturing hair follicles

41 upvotes 8 years ago

A new stem cell method for culturing hair follicles is being developed as an alternative to Minoxidil, finasteride, and RU58841. There are concerns about its cost and accessibility despite plans for commercialization.

community Wait, so retinol actually helps with hair growth? I heard it was the other way around a while ago and just accepted it..

6 upvotes 7 years ago

Retinol can help with hair growth, contrary to previous beliefs. Treatments discussed include Minoxidil, finasteride, and RU58841.

community The new growth in hair loss research: With increasing evidence of its impact on mental health, scientists are pushing forward with breakthroughs on balding. Later this year, scientists will launch one of the first ever clinical trials with hair follicles grown entirely from stem cells.

324 upvotes 7 years ago

Hair loss impacts mental health, with treatments like Minoxidil, finasteride, and stem cell transplants discussed. There is hope for future breakthroughs, but current treatments are limited, and awareness is lacking.
