This study offers evidence suggesting a probable causal role of certain gut microbiota in the development of alopecia areata.

In this study, aspartame consumption during gestation in rats was associated with significant histological changes and increased apoptosis in the skin of their neonatal pups.

Men with early balding should be checked for metabolic syndrome, as there's a link between the two.

In this study, oral administration of strawberry guava extract promoted hair growth in both mice and humans, with active components like adenosine, fructose, digalactosyldiacylglycerol, and pedunculagin contributing by enhancing skin blood flow and activating dermal papilla cells.

This study evaluated an herbal emulgel formulation containing extracts from Wedelia chinensis and Cassytha filiformis for hair growth promotion in rats, finding that the combined formulation significantly increased hair growth compared to both individual extracts and the control group.

This review discusses recent advancements in hair follicle organoid technology for alopecia treatment but presents no new experimental results, emphasizing the potential for clinical applications and drug screening.

This study highlighted the promising health benefits of taxifolin, a flavonoid with antioxidant, anti-inflammatory, and other protective effects found in foods like onions and milk thistle, though more research is needed to fully understand its mechanisms and safety for human therapeutic use.

In this study, researchers found that sesamin, a component of sesamum, modulated the AR-MAPK-Wnt signaling pathway in DHT-stimulated HaCaT keratinocytes, demonstrating potential multi-target activity against molecular events in androgenetic alopecia.

This study found that a catechins-rich Assam tea extract demonstrated antioxidant effects and hair growth promotion in mice, suggesting its potential as a natural alternative for treating hair loss.

This review integrates studies on mouse models and human clinical observations to highlight the role of immune cells in skin development and how their dysregulation leads to skin disorders, suggesting potential therapeutic pathways for skin regeneration.

This study revealed that during avian skin development, complex tissue architecture results from specific cellular flows and mechanical processes that guide feather bud protrusion and elongation, with distinct differences noted in scale development, where rigidity restricts such transformations.

This study analyzed the therapeutic potential of various plant species for alopecia areata treatment, highlighting their possible benefits due to anti-inflammatory and immunomodulatory properties, though more research is needed to fully understand the mechanisms involved.

The study introduced an advanced skin model, ImmuSkin-MT, which effectively distinguished between different strengths of skin sensitizers by mimicking the interaction of immune cells in skin tissue.

In this study, human dermal papilla cells exposed to wasabi leaf extract showed changes in cytokine-related gene expression, which the authors suggest could help clarify the biological effects of wasabi.

This review discusses nine Ayurvedic medicinal herbs listed in the Dhanvantari Nighantu as beneficial for hair, detailing their properties like promoting hair growth, enhancing hair thickness, and maintaining dark hair color, alongside supporting research on these effects.

In this study, the researchers reported that a newly developed PYGL inhibitor, HTPI, enhanced hair growth in an ex-vivo culture by reducing oxidative damage in hDPCs and inhibiting glycogen degradation in hORSCs, showing potential as a treatment for hair loss comparable to minoxidil.

In this study, a medicated hair growth tonic containing RJ extract increased hair counts, the proportion of anagen phase hairs, and scalp moisture in human trials, although the specific role of RJ in hair growth remains unclear due to other active ingredients.

This study found that 12.5% moringa seed oil demonstrated optimal anti-alopecia activity in rabbits, significantly improving hair weight compared to the treatment with 0.1% finasteride.

This study found that Biofield Energy Healing Treatment significantly increased the proliferation of human hair follicle dermal papilla cells in vitro, suggesting potential as a hair growth enhancer.

This study found that both Th1 and Th2 cytokine markers were elevated in the serum and skin of patients with alopecia areata, with Th2 markers more closely linked to disease severity.

This study found that activation of the transcription factor Nrf2 in keratinocytes promotes wound healing in mice by expanding hair follicle stem cells, independent of changes in keratinocyte proliferation or migration.

In this study, topical tofacitinib significantly promoted hair regrowth in mice, outpacing both minoxidil and controls over 21 days, with findings suggesting increased VEGF levels and decreased inflammation as possible mechanisms.

In this study, researchers found that Biofield Energy Healing Treatment significantly increased the proliferation of human hair follicle dermal papilla cells in vitro, suggesting potential hair growth benefits.

This study found that 448-kHz Capacitive-Resistive Electrothermal Therapy led to a significant increase in hair density in women with Female Pattern Hair Loss, likely due to stimulated proliferation of dermal papilla cells.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This study found that stress increases the number of peptidergic nerve fibers and mast cell activity in mouse skin, suggesting a significant neuro-immune interaction under stress.
