In this study, researchers found that stabilizing the protein HIF1A in hair follicles promotes glycolysis over oxidative phosphorylation, potentially reducing oxidative stress and supporting hair growth.

This study suggests that human hair follicles may operate their own Cori cycle, synthesizing glycogen from lactate under conditions of lactic acidosis.

This review discusses the use of cultured hair follicles for studying hair growth regulation and reports the challenge of modeling the entire hair cycle in vitro.

This study found that in AGA, the risk allele at locus 2q35 alters WNT10A expression through EBF1, suggesting a potential androgen-dependent regulatory mechanism.

High MUC-18/MCAM levels in blood indicate a worse outlook for melanoma patients.

In this study, the researchers developed an in vitro model that maintains human hair follicles to grow at in vivo rates and observed that factors like EGF and IGF-I influence hair follicle growth and catagen entry.

GLI2 activates GLI1, promoting skin tumor growth and hair development.

This study found that balding dermal papilla cells show premature senescence and altered expression of stress and DNA damage markers, suggesting sensitivity to environmental stress in androgenetic alopecia.

This review discusses various in vitro and in vivo models for studying hair follicle function, noting their potential in developing new treatments for hair disorders but reports no new results.

This study suggests that Myc superfamily transcription factors may have distinct roles in different epithelial compartments of the human hair follicle, possibly influencing cell fate in the putative stem cell compartment.

This study found that mitochondrial dysfunction and higher oxidative stress in balding dermal papilla cells may contribute to androgenetic alopecia, with antioxidants potentially improving metabolite uptake.

This study investigated the effects of substance P on human hair growth but found its role in hair follicle physiology remains unclear.

This study found that hair follicle stem cells in mice have an unexpected ability to adaptively determine their differentiation pathways, maintaining tissue architecture despite external stimuli.

This study found that SesZen-Bio TM, a proprietary extract from Sesbania grandiflora leaves, increased proliferation of hair cells and hair shaft length in vitro and ex vivo, potentially due to activation of the Wnt/β-catenin signaling and stem cell differentiation pathways.

This review discusses the use of Dermal Papilla cells as in vitro models for studying hair growth modulators, emphasizing their role in aiding the development of new hair treatments, but reports no new clinical results.

This study demonstrated that intact adult human dermal papillae can induce hair growth when implanted into mouse hair follicles, highlighting their potential for advancing hair follicle biology and therapeutic approaches.

This review discusses the role of estrogens in hair follicle cycling and the skin, highlighting the need for more research on estrogen signaling pathways and their interactions with other factors in hair biology.

Higher IGF-1 levels in hair follicles link to better finasteride results for hair loss.

This review discusses the steroidogenic properties of human skin and suggests that impaired steroidogenesis may be linked to conditions like acne, rosacea, atopic dermatitis, and androgenic alopecia, but reports no new clinical results.

This study found that Minoxidil had biphasic effects on normal human keratinocytes, stimulating proliferation at micromolar doses, but showing antiproliferative, pro-differentiative, and cytotoxic effects at millimolar concentrations.

In this study, researchers found that overexpression of IGF-1 in transgenic mice stimulated increased vibrissa growth during the first neonatal hair cycle compared to their nontransgenic littermates.

This study found that minoxidil did not significantly increase hair shaft elongation in ex vivo human hair follicle culture, questioning the suitability of this method for studying its hair-growth-promoting effects.

Finasteride potentially treats hair loss by reducing DHT production.

This study found that dermal papilla cells from balding scalp follicles secrete significantly less insulin-like growth factor-1 and its binding proteins, suggesting a mechanism contributing to male pattern baldness.

This study found that women with female pattern hair loss had increased 5α-reductase isozymes and decreased aromatase mRNA levels, potentially affecting their response to treatment.

This study found that t-flavanone may promote hair growth in people with androgenic alopecia by enhancing hair anchoring strength and upregulating desmoglein expression in hair follicles over 30 weeks.

This study found that topical application of triiodothyronine (T3) can induce the transition of hair follicles from the telogen to the anagen phase in mice and stimulate hair shaft growth in vitro.

This study found that knocking down P-cadherin expression in cultured human hair follicles recreates the hair abnormalities seen in patients with hypotrichosis with juvenile macular dystrophy.

In this study, the researchers observed that Biofield Energy Healing Treatment significantly increased hair follicle cell proliferation in human dermal papilla culture, suggesting potential as a hair growth enhancer.

In this study, researchers found that alopecia areata patients show a significant reduction in suppressive regulatory T-cells and an increase in inflammatory T-cell populations, suggesting an immunological imbalance contributing to the disease.
