In this study, pediatric hair and scalp disorders were effectively diagnosed using trichoscopic and light microscopic examinations, demonstrating high agreement with clinical diagnoses and emphasizing their utility as reliable, non-invasive diagnostic tools in a hospital-based setting.

In this study, researchers used SEM/SDD-EDS to identify waterborne minerals like calcium and aluminum in the scalp hair cuticle of individuals using treated or untreated water for hair washing, finding that prior application of coconut oil or conditioners can prevent calcium uptake.

Reflectance confocal microscopy can tell apart white dots on the scalp as either sweat gland ducts or hair follicle openings.

This article evaluates reflectance confocal microscopy features of scalp melanoma but reports no new clinical results, suggesting further investigation is needed.

This study found that near-infrared microscopy can effectively detect complete medulla loss in scalp hair, which may serve as a potential biomarker for breast cancer diagnosis.

This study found distinct sex-based differences in the microscopic characteristics of scalp hair among a Nigerian population, providing valuable forensic data specific to this group.

Zinc deficiency causes early scalp hair damage that recovers slower than skin symptoms.

This study found that a patient with giant axonal degeneration had unique hair abnormalities such as trichorrhexis nodosa and altered S:N ratios, unlike her relatives but comparable to unrelated controls.

This review highlights that microscopic analysis of human scalp hair remains crucial in forensic science for crime scene investigations, despite limitations such as subjectivity and potential misidentification, and notes that integrating DNA analysis and digital imaging could enhance accuracy.

This study found that a new 12-point scale provided a more precise measurement system for evaluating hair damage and improvement after hair care product use compared to a 5-point scale.

This study used advanced analytical techniques to reveal that proteins and lipids are distributed unevenly in hair, with distinct structural differences depending on their location within the fiber.

This study describes the anatomy of arrector pili muscles in scalp hair follicular units, proposing a model where a single muscle structure is shared by all follicles within a unit.

In this in-vitro study, researchers found that shampoo-induced coacervates structurally resemble cationic polymers and contain anionic surfactants that may stimulate the scalp upon exposure to water.

This case report describes a giant pigmented tumor of the scalp in a 47-year-old woman and suggests a possible dual origin involving neural crest differentiation.

This article discusses using cosmetic hair products alongside medical treatments for hair conditions to enhance patient self-esteem and quality of life, without reporting new clinical results.

This article discusses aspects of evaluating patients with androgenetic alopecia for hair transplantation and reports no clinical results.

This review discusses the role of scalp imaging techniques in trichology for researching drug delivery and toxicology, without presenting new clinical results.

USB videodermatoscopes are a practical and affordable alternative for diagnosing skin conditions.

This article reviews the rationale and science behind forensic hair examinations and discusses the role of microscopic and DNA techniques in differentiating hair sources but reports no new findings.

This study observed that hair casts, seen in girls with tightly drawn hairstyles, may result from local circulatory disturbances and scalp inflammation.

Reflectance confocal microscopy is a useful, non-invasive tool for diagnosing some skin diseases, with potential for future improvements.

This study found that aging in Korean individuals is associated with changes in hair diameter and surface structure, as observed through atomic force microscopy.

Hair from people with seborrheic dermatitis is thicker scaled, more damaged, and thinner than healthy hair, and atomic force microscopy can help monitor the condition.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

This study presents a case of a 6-month-old infant girl with hypotrichosis and an alopecic plaque in the occipital region, characterized by broken and dystrophic hairs with follicular papules and perifollicular hyperkeratosis, suggesting a diagnostic consideration.

This study describes a modified reduction-osmication method for staining human scalp hair that improves reagent penetration and visualization of hair cortex features using transmission electron microscopy.

In this study, researchers developed a method using scalp cyanoacrylate biopsy and advanced imaging techniques to effectively measure and visualize the distribution of anti-dandruff shampoo ingredients zinc pyrithione and climbazole within the scalp follicular infundibulum.

This review discusses the evolution of hair plucking techniques for diagnosing hair disorders and suggests uniform methods could improve consistency in evaluating hair growth and treatment.

A woman developed rare, unexplained curly hair on her scalp and eyelashes.

This review discusses the epidemiology, risk factors, clinical features, and management of scalp melanomas, highlighting their high mortality rates and specific challenges in diagnosis and treatment; it reports no new research findings.
