This article reviews skin disorders in Parkinson's disease, highlighting the potential of skin studies and stem cell research to advance understanding and treatment of the neurodegenerative disorder, without presenting new results.

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

This study found that untreated hirsute patients have lower expression of type 2 17β-HSD mRNA in scalp hairs, indicating potential disturbances in androgen metabolism, compared to treated hirsute patients.

This study reported that 6 months of finasteride treatment significantly improved idiopathic hirsutism in women, with benefits persisting 6 months post-treatment and no adverse reactions observed.

This article reviews the potential neuroprotective effects of 17α‐estradiol in neurodegenerative diseases and highlights its possibly lower toxicity compared to more feminizing hormones, but it reports no new clinical findings.

This study found that arctiin, a compound from Arctium lappa, demonstrated protective effects against oxidative stress-induced dysfunction in human hair dermal papilla cells, suggesting potential therapeutic use for alopecia.

This review discusses the generation of germ cell-like cells from skin-derived stem cells and reports no new results; the potential for these cells to produce viable progeny remains unclear.

This study found that specific SHBG gene variants and haplotypes are associated with polycystic ovary syndrome, suggesting that SHBG may be a candidate gene for the condition.

This study demonstrated that a 3D air–liquid culture system using Wnt-CM-treated cells can induce hair regeneration in nude mice and may facilitate large-scale preparation for hair loss treatment.

In this study, DHT was observed to have varying effects on hair follicle growth and related protein expression depending on concentration, with the Wnt/β-catenin pathway potentially playing a significant role.

This review discusses the potential of nanotechnology-based formulations for delivering topical minoxidil to improve hair loss treatment outcomes and reports no new clinical results, urging further research into their benefits and safety considerations.

This study found that millimolar concentrations of minoxidil in the skin induced VEGF production through HIF-1 stabilization by inhibiting PHD-2, implying a molecular mechanism for hair growth promotion.

This review explores the mechanisms, techniques, and clinical applications of microneedling, highlighting its advantages and challenges in skin rejuvenation, and discusses future innovations in the field as it continues to evolve.

This study found that women with polycystic ovary syndrome have elevated cardiovascular risk markers, with levels being higher in obese participants compared to non-obese participants.

This study examined the structural and biochemical mechanisms of human lipocalin prostaglandin D synthase, detailing substrate and product binding processes at the catalytic site and suggesting potential for drug delivery targeting hydrophobic molecules.

This study found that lipin 1β expression in both visceral and subcutaneous adipose tissue is significantly lower in PCOS patients compared to controls, suggesting its involvement in the pathogenesis of insulin resistance.

This study found that 5% primed conditioned medium from human umbilical cord blood-derived mesenchymal stromal cells significantly improved hair density, thickness, and growth rate in patients with androgenetic alopecia.

This study concluded that neither basal nor ACTH-stimulated 17-OHP concentrations effectively indicate carrier status for 21-hydroxylase deficiency among Slovenian hyperandrogenic women, recommending molecular analysis of the CYP21 gene for reliable screening.

This study found that ZP4 expression was highest among PCOS patients with regular menstrual cycles, which may be linked to mature follicle presence, but no correlation with clinical indices was observed.

In this study, low-dose finasteride (2.5 mg/day) significantly reduced hirsutism scores in women over 12 months without significant hormonal changes or serious side effects.

This study found that linoleic acid from Malva verticillata seed extracts may promote hair follicle cell growth and counteract hair loss signaling in a lab setting.

This review analyzes the impact of different preparation methods for platelet-rich plasma, human follicles stem cells, and adipose-derived stem cells on hair regrowth and wound healing, but reports no new results; the authors emphasize convincing evidence of positive outcomes despite protocol variability.

This study suggests that Houttuynia cordata extract may promote hair growth by stimulating dermal papilla cell proliferation and extending the anagen phase through enhanced energy metabolism and gene expression changes.

This study found that micro-current electrical stimulation may promote hair growth in human hair follicle-derived papilla cells and a mice model by enhancing cell proliferation, migration, and activating key growth pathways.

This study suggests that epigallocatechin gallate (EGCG) from green tea may counteract DHT-induced hair follicle damage by modifying the miRNA expression profile in human dermal papilla cells.

This review discusses the range of cutaneous immune-related adverse events induced by immune checkpoint inhibitors and the proposed mechanisms underlying these skin reactions, but reports no new clinical results.

This study found that ethanol extract of Tubtim Chumphae rice bran downregulates SRD5A gene expression, similarly to finasteride, suggesting potential use as an anti-hair loss product.

This review article summarizes the potential role of advanced medical therapies—using genes, cells, and/or tissue engineering—in treating various types of alopecia, by examining clinical research, basic studies, and ongoing trials.

This review discusses the potential of cell-derived nanovesicles as innovative treatment strategies for hair growth and provides no new clinical results; the authors emphasize the need for further understanding of their mechanisms.

This study found that diphencyprone showed a significant clinical response for treating alopecia areata, while tacrolimus was not effective.
