Human Hair Growth Ex Vivo Is Correlated With In Vivo Hair Growth: Selective Categorization of Hair Follicles for More Reliable Hair Follicle Organ Culture

research Human hair growth ex vivo is correlated with in vivo hair growth: selective categorization of hair follicles for more reliable hair follicle organ culture

27 citations , November 2005 in “Archives of Dermatological Research”

This study found that selecting human hair follicles at a defined anagen stage based on their in vivo growth rate leads to more consistent results in organ culture, with minoxidil significantly enhancing hair growth in these follicles.

research Evaluation of the activity of laser light doses compared to an inactive control dose on ex vivo hair growth

February 2010 in “Journal of The American Academy of Dermatology”

This study found that NB-002 demonstrated clear antifungal activity and clinically significant nail clearing in subjects with distal subungual onychomycosis and ≤50% nail involvement, compared to a vehicle treatment.

research Ex-vivo Hair Growth Promotion Efficacy of Biofield Energy Treated Williams Medium E using Vibrissae Hair Follicle Organ Culture

December 2018 in “Zenodo (CERN European Organization for Nuclear Research)”

This study observed that Biofield Energy Treated William’s Medium E increased telogen follicle formation in vibrissae hair follicle culture cells, suggesting potential hair growth promotion.

Prostaglandin F2α Stimulates Growth of Human Intermediate Hair Follicles in Ex Vivo Organ Culture with Potential Clinical Relevance

research Prostaglandin F2α stimulates the growth of human intermediate hair follicles in ex vivo organ culture with potential clinical relevance

June 2025 in “Frontiers in Physiology”

This study demonstrated that PGF 2α significantly stimulates hair growth in human hair follicles via a receptor-driven mechanism, with a notably stronger response in intermediate follicles than in terminal ones, suggesting potential clinical significance for conditions like alopecia.

Hair Growth-Supporting and Follicle-Protective Potential of a Botanical-Based Supplement Ingredient: In Vitro, Ex Vivo, and Molecular Docking Studies

research Hair Growth-Supporting and Follicle-Protective Potential of a Botanical-Based Supplement Ingredient: In Vitro, Ex Vivo, and Molecular Docking Studies

August 2026 in “Biomolecules”

This study suggests that Elissara® may support follicular resilience by targeting multiple pathways associated with follicular health in preclinical models, although clinical studies are needed to confirm benefits for hair growth.

4 upvotes 3 months ago

The user started using Agerin cream on their scalp and noticed some hair growth, despite not applying it consistently. They also use Minoxidil, RU58841, dutasteride, and finasteride, and have seborrheic dermatitis.

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 PP405: The Ultimate Hair Loss Drug for Complete Hair Growth

211 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 new way to activate stem cells to make hair grow

42 upvotes 7 years ago

Stem cell-related treatments and drugs like RCGD423 and WAY are being tested for hair growth. Clinics are conducting tests on patients who haven't had previous treatments.

chemical that might completely regrow follicles from hair transplant extractions

learn Exosomes

Can an exosome treatment revive hair follicles that have stopped producing hair? Exosome treatment may help revive dormant hair follicles, but results vary.

learn Vascular Endothelial Growth Factor

Can products that stimulate Vascular Endothelial Growth Factor (VEGF) improve blood flow to hair follicles? Yes, products that stimulate VEGF may improve blood flow to hair follicles.
What is Vascular Endothelial Growth Factor (VEGF), and how does it support hair growth in alopecia? VEGF promotes hair growth by enhancing blood supply to hair follicles.
Is Vascular Endothelial Growth Factor (VEGF) available as a topical treatment, or is it only stimulated indirectly? VEGF is not available as a topical treatment for hair loss.

learn Latanoprost

How long does it usually take to see results from latanoprost for hair growth? There is no established timeline: the only human scalp trial, a 16-man pilot, measured a hair-density increase at 24 weeks using latanoprost 0.1% — twenty times the strength of the glaucoma eye drop — and faster figures quoted elsewhere come from eyelash and animal observations. Scalp use is off-label and experimental.
