This study reported a similar prevalence of metabolic syndrome in patients with alopecia areata as in healthy controls, with no statistically significant differences observed.

This study investigated the role of autophagy in human dermal papilla cells and found that inhibiting autophagy accelerates the catagen phase by reducing Wnt/β-catenin signaling. Furthermore, adding ginsenoside Re appears to restore autophagy, suggesting potential benefits for mitigating hair loss linked to autophagy inhibition.

This review outlines how peptidyl arginine deiminases (PADIs) and protein citrullination are involved in hair follicle regeneration and inflammatory alopecia, but presents no new clinical findings.

This study found that exosomes derived from human adipose stem cells significantly enhanced the proliferation and migration of dermal papilla cells compared to those from platelet-rich plasma, suggesting potential benefits for hair loss treatment.

This study introduced a simple and reliable in vitro assay capable of large-scale simultaneous screening of hair growth-promoting compounds using a 3D co-culture system of human dermal papilla and outer root sheath cells.

This study found that women with polycystic ovary syndrome have higher triglyceride and fasting glucose levels in obese individuals and higher total cholesterol levels in non-obese individuals compared to healthy women.

This study identified an association between premature hair greying and larger waist circumference among young healthy subjects.

This study demonstrated that human hair keratins have strong antioxidative properties, providing protection against oxidative stress in human dermal fibroblasts, suggesting their potential as antioxidizing supplements.

This study found that heat-killed Enterococcus faecalis EF-2001 promoted hair regrowth in mice, likely by increasing the expression of growth factors and marker genes.

This study found that serum HDAC1 levels are significantly higher in patients with alopecia areata compared to those with acne vulgaris and healthy controls, suggesting potential therapeutic opportunities for HDAC inhibitors.

This study demonstrated that electrical stimulation via a polypyrrole-modified electrode enhanced trichogenic gene expression in human dermal papilla cells, leading to increased hair growth in a mouse model.

This study found that women with PCOS had higher body fat and worse insulin resistance than non-PCOS women, with body composition influencing metabolic profiles independently of PCOS status.

This study identified 374 eQTLs in scalp hair follicles associated with genes involved in metabolic, mitotic, immune processes, and responses to steroid hormones, contributing insights into genetic variation and hair traits.

This study reports the creation of a human dermal mesenchymal-like stem cell line from an androgenetic alopecia patient, which may serve as an in vitro model to explore alopecia mechanisms.

This study found that premenopausal women with female pattern hair loss had a higher prevalence of metabolic syndrome compared to healthy controls.

This study found that the purified compound VB1 from Vitex negundo seeds may reduce UVA-induced skin aging by targeting MAPK1 and demonstrated its potential in mice.

In this study, blue light-irradiated nanovesicles derived from human adipose-derived stem cells enhanced dermal fibroblast proliferation and extracellular matrix synthesis, improving skin maintenance and hair follicle regeneration, suggesting a novel therapeutic strategy for skin and hair disorders.

This study observed that many women with PCOS had unfavorable lipoprotein profiles, mostly moderate changes in triglycerides, HDL, and LDL cholesterol, with small LDL particles not being rare and potentially aiding risk assessment.

This study found that renin and d-dimer levels were significantly higher in PCOS patients, particularly those also infected with COVID-19, compared to non-PCOS women.

This study found that a 12-week supplementation with MePL, a solution of miliacin encapsulated within polar lipids, significantly reduced hair density in the telogen phase and improved scalp dryness and hair brightness in women with telogen effluvium.

This study found that epigallocatechin-3-gallate (EGCG) may reduce paclitaxel-induced apoptosis in human dermal papilla cells by regulating microRNA expression related to apoptosis and cell proliferation.

This study found that a 4:1 combination of Rhynchosia nulubilis and Polygonum multiflorum extracts significantly promoted the proliferation of human dermal papilla cells and alleviated testosterone-induced cytotoxicity, suggesting potential for treating hair loss and related disorders through a synergistic approach.

This Mendelian randomization study suggests a causal link between higher BMI and increased risk of psoriasis, atopic dermatitis, and hidradenitis suppurativa, potentially due to elevated biomarkers such as triglycerides and C-reactive protein.

This study found that patients with premature greying of hair had significant abnormalities in cardiovascular risk markers, including elevated IL-6 levels, compared to healthy controls.

This study found that overexpression of miR-122 in balding hair follicles may induce apoptosis in human dermal papilla cells by repressing IGF1R, suggesting a new potential pathological mechanism in androgenetic alopecia.

This study found that injectable platelet-rich fibrin (i-PRF) enhances hair follicle regeneration in vitro by promoting human dermal papilla cell proliferation, migration, and trichogenic inductivity, with varying effects depending on concentration.

This study found significant associations between polycystic ovary syndrome and increased serum levels of reproductive hormones, as well as connections to infertility, hirsutism, and metabolic syndrome in Yemeni women.

This Mendelian randomization study reports that lifelong increased free testosterone in males was associated with improved bone mineral density and body composition but increased risks of prostate cancer, hypertension, and several other conditions.

In this animal study, lavender oil, Eruca sativa oil, Aloe vera oil, and sodium carbonate decreased lipid levels and tumor markers in breast cancer models, suggesting potential benefits as adjunctive therapy during chemotherapy.

This study found that histidine decarboxylase is crucial for the hair-inducing ability of newborn mouse dermal cells, with its expression significantly decreasing in the first few days after birth.
