research Putting the Human Hair Follicle Cycle on the Map

8 citations , January 2016 in “Journal of Investigative Dermatology”

This review discusses the use of the human-on-mouse xenograft model for studying the human hair follicle cycle and emphasizes its utility for pharmacological testing, without reporting new clinical results.

research A primer for studying cell cycle dynamics of the human hair follicle

38 citations , April 2016 in “Experimental Dermatology”

This review discusses immunohistological and immunofluorescent methods for studying the human hair follicle cell cycle, reporting no new results, and suggests its potential for advancing cell cycle research.

research Human hair follicles operate an internal Cori cycle and modulate their growth via glycogen phosphorylase

30 citations , October 2021 in “Scientific Reports”

This study found that human scalp hair follicles can internally operate a Cori cycle, synthesize glycogen in the presence of lactate, and modulate growth through glycogen phosphorylase activity.

research Nonanal Stimulates Growth Factors via Cyclic Adenosine Monophosphate (cAMP) Signaling in Human Hair Follicle Dermal Papilla Cells

8 citations , October 2020 in “International Journal of Molecular Sciences”

This laboratory study found that nonanal, a plant scent compound, may stimulate growth factors and cell proliferation in human hair follicle dermal papilla cells, suggesting a cAMP-mediated mechanism.

research Effects of Bioactive Composition in Oryza sativa L. cv. KDML105 Bran Extract on Gene Expression Related to Hair Cycle in Human Hair Follicle Dermal Papilla Cells

3 citations , January 2023 in “Agronomy”

This research reported that KDML105 bran extract demonstrated antioxidant activities, reduced nitric oxide production, and influenced gene expression related to the hair cycle in cultured dermal papilla cells, suggesting potential as an anti-hair loss agent by supporting the anagen phase and angiogenesis.

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 Researchers working on ways to regenerate lost hair from stem cells identified a recipe for normal hair regeneration in the lab. “A method for cyclical regeneration of hair follicles from hair follicle stem cells and will help make hair follicle regeneration therapy a reality in the near future.”

263 upvotes 5 years ago

Hair loss treatments like finasteride, minoxidil, and hair transplants have side effects and limitations. There is hope for future advancements in stem cell therapy and hair follicle regeneration, though skepticism about their effectiveness and timeline persists.

community PP405 Won't Work Long Term: Hair Follicle Damage Due to Abuse of the ISR System

67 upvotes 11 months ago

PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.

community Chinese reseachers successfully create hair follicles in-vitrofor autologous transplantation in vivo

29 upvotes 1 year ago

Chinese researchers have successfully created hair follicles in vitro, potentially offering unlimited hair for transplantation and a cure for hair loss. They plan to test these follicles in vivo on human scalps.

community Hair cloning breakthrough, this might just be the big one ?

418 upvotes 6 months ago

Japanese scientists discovered ABM cells, enabling successful human hair follicle cloning, potentially curing hair loss. The treatment may be available in Japan by 2028, but it will be expensive and require travel.

learn KY19382

compound that activates Wnt/β-catenin to promote hair regrowth and create new hair follicles

learn Osteopontin

signaling protein that, when suppressed, may grow hair by reducing inflammation and stem cell loss

learn Melatonin

hormone commonly taken for sleep aid has some topical benefits for hair

learn GHK-Cu

a copper peptide showing promise in both regrowth and reversing gray hair

learn Follistatin

glycoprotein that inhibits TGF-β and promotes hair growth by antagonizing activin

What is follistatin, and how does it influence hair follicle growth and regeneration? Follistatin blocks activin and related growth-inhibiting proteins, which in laboratory and animal work is described as keeping hair follicles in their growth phase; the only verifiable human evidence is a single small 2011 phase 1 injection trial, so follistatin remains experimental and is not an approved hair-loss treatment.

learn Fluocinolone

Can long-term use of Fluocinolone affect the health of hair follicles? There is no long-term human trial measuring what topical fluocinolone does to hair follicles; what is documented is the label's warning about skin atrophy with prolonged use, plus a 2007 mouse study suggesting hair-follicle bulge stem cells do not repair steroid-induced atrophy.

learn sh-Polypeptide-7

How does sh-Polypeptide-7 help stimulate hair follicle activity or reduce scalp inflammation? sh-Polypeptide-7 is the INCI name for a lab-made form of human growth hormone (somatotropin) — not EGF, which is sh-Oligopeptide-1. Growth hormone and IGF-1 signalling is documented in hair follicle biology, but there is no published human trial of sh-Polypeptide-7 applied to the scalp for hair growth or scalp inflammation.

learn SCUBE3

How does SCUBE3 work on hair follicles compared to treatments like minoxidil or finasteride? Laboratory research in mice reports that SCUBE3, a protein released by dermal papilla cells, signals dormant follicles to grow through the TGF-β pathway downstream of Hedgehog; minoxidil and finasteride instead work on blood flow to the follicle and on DHT, and unlike SCUBE3 they have decades of human trial data behind them. SCUBE3 has not been tested in human clinical trials and is not available as a medicine.

learn Sulforaphane

How often should sulforaphane-based products be used for hair loss prevention? No human trial has tested sulforaphane for hair loss prevention, so there is no established usage frequency. Oral supplements are taken daily in research on unrelated conditions and the hair-specific evidence is limited to cell, mouse and isolated-follicle studies, so any schedule is extrapolation rather than a dosing guideline.
