This review discusses how menopause affects skin structure and function, finding associations between menopause and common skin conditions, but reports no new clinical results.

This study reported that patients with alopecia areata have reduced expression of the melanocortin receptor MC2R in their scalp tissues compared to normal scalp, indicating potential involvement in the condition's pathophysiology.

In this study, researchers found that frontal hair follicles in individuals with androgenetic alopecia show a higher biological age compared to occipital follicles, possibly due to decreased expression of the transcriptional repressor TRPS1 in frontal dermal papillae, which may influence follicle miniaturization.

Eating isoflavone can help mice grow hair by increasing a growth factor.

This study demonstrates that FMOD deficiency in mice alters TGF-β ligand and receptor expression during wound healing stages, leading to delayed wound closure and increased scar size.

This study found that Sophora flavescens extract may promote hair growth in mice by inducing earlier hair cycle changes and regulating growth factors in dermal papilla cells.

Zinc deficiency in monkeys causes skin issues and reproductive problems, but supplementation reverses these effects.

Fibronectin and other basement membrane components increase during hair growth and decrease during rest.

Platelet-rich plasma (PRP) may help promote hair growth and improve graft survival after hair transplantation, but more research is needed to confirm its effectiveness and determine the best dosage.

This study presents a method for directly measuring the solubility of solid chemicals in the skin's stratum corneum under various humidity conditions, emphasizing its importance for dermal drug delivery and chemical safety assessments.

This study found that elevated expression of the protein Zyxin in hair follicles is associated with androgenetic alopecia and suggests it may be targeted for therapy.

This study found that activin A signaling is crucial for hair follicle neogenesis in human dermal papilla 3D cultures combined with mouse epidermal cells.

This study found that calcium and all-trans retinoic acid affect the proliferation and differentiation of goat hair matrix cells, which are essential for cashmere growth research.

This chapter reviews common cosmetic dermatology techniques but presents no new findings; it discusses treatments like emollients and laser therapy for conditions like photoaged skin and acne scarring.

This chapter reviews signaling pathways related to androgenic alopecia in dermal papilla cells of balding human scalps, integrating published information and analysis of molecular interactions, without reporting new clinical results.

This study found that a novel Mito-Activator Complex, containing nicotinamide and epigallocatechin gallate, significantly increased hair density and growth in a 6-month human trial, with no adverse effects reported, potentially offering a new approach to hair loss treatment through mitochondrial activation.

In this study, the combination of low level light therapy with arginine, arterial extract, or biotin tripeptide-1 was associated with improvements in hair density and follicle structure in androgenic alopecia.

This study explored whether inositol and phytic acid, components from rice bran, could be effective and safe alternatives to minoxidil for promoting hair growth, due to concerns about minoxidil's side effects with long-term use in women. Results are not reported.

This study found that CXCL12 inhibits hair growth via the CXCR4/STAT signaling pathway, suggesting that targeting this pathway could be a promising approach for promoting hair growth.

In this study, LED irradiation was found to promote hORSC proliferation and stimulate the Wnt5a/β-catenin and ERK signaling pathways, suggesting a potential mechanism for hair growth.

This study systematically reviewed 43 articles on the role of fibroblasts, especially dermal papilla cells, in androgenic alopecia, identifying androgen signaling and related pathways as key drivers of hair follicle miniaturization, which supports targeting dermal papilla cell dysfunction as a therapeutic strategy.

This infographic compares the safety profiles of SH‑1, a cosmetic ingredient, which showed no systemic absorption, and PP405, an investigational drug with dose-dependent systemic uptake and potential threshold breaches, highlighting differences in safety between cosmetic and investigational substances according to this report.

Elevated luteinizing hormone contributes to female-pattern hair loss, and blocking certain channels may help prevent it.

In a rat scalp expansion model, this study found that activating autophagy with rapamycin enhanced skin regeneration during tissue expansion by increasing expanded skin area, epidermis and dermis thicknesses, cell proliferation, angiogenesis, and other regenerative factors, whereas blocking autophagy reversed these effects.

This study found that stabilizing HIF1A in hair follicle cells promoted a shift to glycolysis, potentially reducing oxidative stress and promoting hair growth, particularly in balding dermal papilla cells.

This study found that Clitocybin A from Clitocybe aurantiaca may promote hair growth in immortalized rat dermal papilla cells by enhancing cell proliferation and activating Wnt/β-catenin signaling and ERK pathways.

Androgens can cause hair growth in some areas and hair loss on the scalp.

This study reports that stimulating sensory neurons with capsaicin and isoflavone increases IGF-I production, promoting hair growth in mice and human volunteers with alopecia.

This study observed that adipose-derived stem cells modified with trichogenic factors have similar properties to dermal papilla cells and show enhanced hair regeneration potential compared to unmodified adipose-derived stem cells.

In this study, repressing β-catenin/Lef1 signalling in mouse epidermis led to progressive hair loss, dermal cysts, and spontaneous skin tumors with sebaceous differentiation, indicating altered keratinocyte differentiation and potential tumourigenic processes.
