5 / 1000+ resultsresearch In vitro 3D organotypic hair follicle-model for high-throughput substance testing
The researchers reported that hydrogels made from methacrylated glycol chitosan and hyaluronic acid with chondroitin sulfate may be suitable for load bearing soft tissue repair, showing enhanced chondrocyte viability and metabolic activity.
research At the dawn of hair research – testing the limits of hair follicle regeneration
This review discusses the potential for cellular hair regeneration by building on foundational rodent studies and emphasizes the need for protocols to enhance the inductive properties of human dermal papilla cells.
research In vitro hair follicle growth model for drug testing
This study found that organoid cultures of human epithelial and mesenchymal cells can produce hair peg-like structures, and their growth is enhanced by minoxidil, suggesting potential for hair drug screening.
research Do follicles matter? Testing the effect of follicles on hair cortisol levels
This study found that cortisol concentrations were significantly higher in hair samples with follicles compared to those without, suggesting potential confounding in stress assessments using different hair sampling methods.

5 / 1000+ resultscommunity So did the experiments with verteporfin for hair transplant scarring regrowth fall through?
Verteporfin reduces scar tissue in hair transplants but doesn't significantly regrow hair follicles. More testing is needed to determine its effectiveness.
community "Hair Follicle Stem Cells are quiescent 99% of the time and permanently reside in the hair follicle"
Hair follicles are mostly dormant but can be reactivated with treatments like minoxidil, finasteride, and microneedling. A new drug, PP405, shows promise for hair regrowth but may not be available until 2027-2028.
community Do hair follicles dies or are dormant ?
Hair follicles can be dormant and potentially revived with treatments like finasteride and minoxidil, but irreversible loss occurs if certain structures are destroyed. Early intervention is more effective, and additional methods like microneedling may help.
community Functional hair follicles grown from stem cells: Scientists have created natural-looking hair that grows through the skin using human induced pluripotent stem cells (iPSCs), a major scientific achievement that could revolutionize the hair growth industry.
Scientists have grown natural-looking hair from stem cells, potentially revolutionizing hair growth treatments. Concerns include cost, DHT resistance, and the need for future procedures.
community Good News, PP405 is out on Shopee
A product called "PP405 Hair Follicle Serum" is being sold on Shopee, claiming to cure baldness without clinical trials or FDA approval, but users are skeptical and refer to it as "snake oil." Some users discuss testing the product's contents, while others share their experiences with hair loss treatments like finasteride.

10 / 61 results- Does niacinamide support hair follicle nutrition? Niacinamide is a precursor of NAD+, a molecule cells use for energy. Whether it affects hair follicles in people has not been tested.
- Will scalp micropigmentation damage my existing hair or follicles? Providers say SMP sits above the hair follicles and does not harm them. No study has tested this, and infection or scarring from any tattoo can affect the skin.
- Can sulforaphane protect hair follicles from inflammation and damage? In lab and mouse studies, sulforaphane reduced markers of inflammation and oxidative stress. No human study has tested whether it protects hair follicles.
- Can daily Fluridil application stop hair follicle miniaturization? The single published fluridil trial (43 men; placebo-controlled for 3 months, then all on fluridil to 9 months) reported more hairs in the growth phase, but it never measured follicle diameter and has not been replicated — so whether daily use stops miniaturization is unproven, and community users describe stabilization rather than regrowth.
- How does folic acid support hair follicle health and growth at a cellular level? Folate is required for the DNA synthesis that fast-dividing hair matrix cells depend on, and severe deficiency causes anemia—but no published trial has given folic acid to people with hair loss and measured the result, so a growth effect is a mechanism, not a finding.
