This study found that keratin film from human hair samples responded to damage from UV, bleaching, perming, and thermal treatments, making it a useful model for evaluating hair damage in product development.

In this study, hair samples from Mexican women were found to be intermediate in diameter and shape between Asian and Caucasian hair, exhibiting high intra- and inter-individual variability and unexpected levels of tensile damage.

This article discusses challenges and limitations of using simple tissue mechanics for repairing head and neck skin defects in trauma and does not report new findings; it highlights potential problems with routine methods.

The Brigham Eyebrow Tool for Alopecia is a simple and reliable way to measure eyebrow hair loss.

Three new techniques simplify and improve the preparation of tissue samples for skin cancer surgery.

This study suggests using a handheld dermatoscope may allow for simple and efficient differentiation of eruptive vellus hair cysts by detecting vellus hair shafts, as demonstrated in a familial case involving five women.

In this study, hair samples from dogs with chronic degenerative valve disease showed significantly higher concentrations of certain endocrine-disrupting chemicals compared to healthy dogs, suggesting a potential link that warrants further investigation.

This study found that platelet-rich gel is a simple and effective non-surgical method for healing exposed skull injuries, resulting in complete healing with minimal scars and sparse hair growth in all patients.

This study found that quantitative trichoscopy is a simple and effective method for determining hair density and thickness in Egyptians, establishing baseline values for clinical hair loss investigations.

This study reports varying levels of potassium and iron in honey samples, contributing to the understanding of mineral content in honey.

This study found that dense-packing hair grafting is a simple, safe, and effective method for restoring scarring alopecia, with high patient satisfaction and significant graft survival rates reported.

This study explored 25-hydroxyvitamin D3 levels in hair samples from participants in Aberdeen and suggested potential links between hair vitamin D levels, seasonal UVB exposure, and marine diet in both modern and archaeological contexts.

This study found that platelet-rich plasma therapy may offer a simple and cost-effective treatment option for androgenetic alopecia in men, with around 70% of participants showing mild to excellent improvement.

This study found that proteomic analysis can distinguish hair samples across different ethnicities and body regions based on keratin protein levels, which may aid forensic hair identification.

In this study, hair samples from breast cancer patients showed increased β-sheet structures and lipid content, with spectral markers successfully identifying cancer in a blind test but also producing false positives.

This study found that the DNA methylation status of skin samples from cashmere goats was higher during the telogen stage compared to the anagen stage, identifying genes potentially important for hair follicle development and growth.

This study found that cortisol concentrations were significantly higher in hair samples with follicles compared to those without, suggesting potential confounding in stress assessments using different hair sampling methods.

This study developed and validated a method using hair samples to simultaneously detect bisphenols and parabens, enabling the quantification of these endocrine disruptors in a hospital population’s hair.

This study found that metabolite levels in hair samples differ significantly by hair color and segment, leading to recommendations for best practices in hair metabolomic studies.

This case study reported TSPyV DNA detection in blood and urine samples before trichodysplasia spinulosa skin lesions developed in a kidney transplant patient under immunosuppressive therapy.

This study found that polyamine levels in hair samples differ between androgenic alopecia and alopecia areata, suggesting potential non-invasive biomarkers to distinguish between these hair loss conditions.

This survey found that over 70% of dermatologists in the sample had prescribed topical minoxidil for hair loss, with low reported complications beyond local irritation.

This study compared RNA-seq results from horse plucked-hair and skin-biopsy samples, finding that plucked hairs were enriched with hair-follicle keratinocytes, while biopsies showed enrichment for other cell types.

This study found that disrupted cholesterol homeostasis in scalp samples from cicatricial alopecia patients hinders hair regrowth by affecting hair follicle stem cell markers, with resulting effects confirmed in vitro and in animal models.

This study found that storing horse hair follicles in RNAlater® at cool or room temperature for up to a week did not affect RNA integrity, suggesting it allows for flexible sample transport without immediate freezing.

In this study, powdered milk samples from Senegal showed varying levels of heavy metals, with some exceeding acceptable maximum levels for calcium, potassium, and phosphorus, indicating potential safety concerns.

This study quantified around 60 organic pollutants in hair samples from mothers and infants in Spain, finding significant correlations between pollutant levels and factors like residence, dietary habits, and maternal age, with common exposure sources identified for several pollutant classes.

This study found that testosterone concentrations in hair samples were moderately stable over three months, with cosmetic treatments like coloring increasing testosterone levels, while natural hair color in untreated hair did not affect testosterone measurements.

This study observed that inflammation in androgenetic alopecia samples was similar to alopecia areata controls, but infundibular and isthmic inflammation were significantly more common in androgenetic alopecia cases.

This study discusses using SEM/EDX for elemental analysis of hair samples in forensic science but notes challenges in detecting certain trace elements from raw hair.
