In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This review discusses the evolution and potential of photobiomodulation therapy, highlighting its transition from skepticism to recognition in medical research; it reports no new experimental findings.

This study reviews the evolution and modifications of microneedle drug delivery systems, initially designed for percutaneous use, now expanded for targeting a variety of tissues and organs such as ocular, oral mucosal, and gastrointestinal, suggesting widespread future applicability.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

This review evaluates existing research on Keratin 15 to assess its validity as a marker for epidermal stem cells, reporting no new results.

This study found that procyanidin oligomers, particularly dimers and trimers, significantly promoted hair growth in mice and hair epithelial cell cultures, suggesting potential use as hair growth agents.

In this study, genetic variation in the CYP19A1 gene, particularly the common rs4646 C allele, was associated with an increased risk of female pattern hair loss, especially in women under 40.

This study found that in young Taiwanese women with PCOS, low sex hormone-binding globulin levels were associated with low HDL cholesterol levels, independent of insulin resistance and obesity.

This review discusses how changes in hair and skin may indicate underlying vitamin deficiencies and emphasizes the need to identify populations at risk for these deficiencies; it reports no new results.

This review discusses the oral manifestations associated with hematologic conditions and nutritional deficiencies, without presenting new research results; it emphasizes the impact of blood disorders and vitamin deficiencies on oral health.

This study found that a 6-month supplementation with omega 3, omega 6, and antioxidants significantly improved hair density and reduced hair loss in women with female pattern hair loss.

This study reports that GLP-1 receptors and proglucagon are expressed in the skin of newborn mice, with GLP-1 potentially playing a role in skin development and hair follicle formation.

This study found that patients with lichen planus were significantly more likely to have dyslipidemia, particularly with higher triglyceride levels.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

This study found that colchicine treatment significantly reduced hair fiber elongation in cultured hair follicles and altered protein expression and activity in dermal papilla cells, suggesting a role for the ubiquitin-proteasome system in its effects.

This study found that lymphatic vessels promote hair follicle growth in mice and may represent new therapeutic targets for hair loss conditions.

This meta-analysis confirmed associations between some androgenic and metabolic parameters in women with PCOS, suggesting that these measurements might help predict metabolic risk in this population.

This study found that long-term dutasteride therapy in men with benign prostatic hyperplasia worsened erectile dysfunction, reduced testosterone levels, and increased blood glucose and lipid profile, indicating negative metabolic impacts.

This article discusses nutritional contributions to hair health and highlights the need for identifying risk factors for deficiencies but reports no new clinical findings.

This study observed that using serial sectioning and d-PAS staining improved detection of Malassezia folliculitis, notably in lesions on the trunks of male patients.

This study found that AHCC significantly reduced alopecia caused by Ara-C in neonatal rats and improved liver function affected by 6-MP and MTX in mice.

Phenobarbitone can cause severe and sometimes fatal skin reactions.

This study found that Secretory Phospholipase A2-IIA (sPLA2-IIA) promotes proliferation through JNK/c-Jun signaling, distinctively affecting normal stem cells and cancer cells, suggesting it as a potential target for cancer treatment.

This study found that young C57BL/6 and BALB/c mice exhibit distinct regenerative patterns during ear wound healing, with greater wound closure but less regeneration in middle-aged C57BL/6 mice.

In this study, researchers found that flavonoid glycosides extracted from Dicerocaryum senecioides leaves significantly promoted hair growth in BalB/c mice, with the shortest hair growth completion time of 19 days compared to the control's 29 days, and dose-dependent results.

This review discusses various follicular unit excision methods, punch designs, and motorized devices, highlighting their roles in reducing hair follicle transection rates and optimizing graft harvesting for individual patient characteristics.

In this study, overexpression of secretory phospholipase A2 Group-IIA in transgenic mice led to depletion of hair follicle stem cells and increased differentiation, linked to changes in histone modifications.

Silymarin improves hair follicle health better than vitamin C by boosting cell growth and reducing oxidative stress.

This chapter defines skin integrity as a blend of intact structural elements and adaptable functional capacity, highlighting its importance in maintaining skin health across various conditions but reports no new research findings.
