This study found that micro-computed tomography (micro-CT) was highly effective for analyzing the cross-sectional geometry of hair fibres, including the medulla in highly curled hair, but less effective than scanning electron microscopy for surface details.

This study suggests that trichoscopy may assist in diagnosing pemphigus, particularly for scalp-specific lesions, by identifying certain characteristic features.

This study found no significant difference in the tensile properties of hair from different scalp positions, suggesting that microscopic structural heterogeneities may play a role.

This article reviews the classification of hair shaft abnormalities, outlining their diagnostic features, but does not present new research findings.

This study found that hair care products containing fermented papaya, fermented mangosteen, and caffeine significantly inhibited hair loss, increased hair density and thickness, and improved hair follicle structure in individuals with androgenic or diffuse alopecia over three months compared to placebo and caffeine controls.

This study found that a proteomics-based approach can effectively distinguish between scalp and pubic hair by identifying unique protein signatures, providing a more quantitative and objective method for tracing hair contamination sources in GMP manufacturing and forensic investigations.

This study developed an in vitro system to analyze human skin progenitor cells' ability to form hair peg-like structures, providing insights for engineering hair follicle organoids.

This study found that while yak belly hair is chemically similar to human hair, its higher porosity and lower mechanical strength limit its usefulness as a substitute in hair dye development.

This review discusses the development and role of corneodesmosin in skin and hair follicle integrity, highlighting findings from mouse models and its connection to genetic diseases, with no new experimental results included.

This study conducted a meta-analysis of gene expression data from alopecia areata patients, identifying 5109 differentially expressed genes and highlighting enriched pathways like JAK-STAT signaling, providing insights into the disease's pathogenesis and potential treatment targets.

This study explored the fungal diversity on human scalps, identifying 15 genera and 24 species from 18 scalp samples of girls, with yeast-like structures found in 33.3% of cases. Additionally, zinc oxide nanoparticles, synthesized using ginger extract, showed significant antifungal activity against specific species.

Childhood hair and scalp disorders can be managed with treatments like cortisone and corticosteroids.

This study used ultrahigh-resolution optical coherence tomography to observe hair shaft structures, finding melanin granules absent only in white hair, which may explain color differences between black and white hair.

This review explores how hair dyes and perms can damage hair structure and notes that while some adverse outcomes like skin irritation and allergic reactions have been reported, evidence from human studies remains inconsistent regarding potential risks, including cancer.

This chapter provides an overview of the complex chemical and physical structure of the hair surface, detailing how factors like ethnicity, environmental stress, and cosmetic treatments can alter its properties and influence the adhesion of hair care products.

This study found that erosive pustular dermatosis of the scalp is frequently misdiagnosed as squamous cell carcinoma, highlighting the need for careful differentiation to avoid unnecessary treatments.

This study found that erosive pustular dermatosis of the scalp is often misdiagnosed as squamous cell carcinoma, highlighting the importance of biopsy for accurate diagnosis.

This study observed that subcutaneously implanted mixtures of human hair follicle cells in nude mice resulted in the formation of hair follicle-like structures, suggesting potential for hair regeneration.

This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.

This review discusses the unique characteristics and disorders of Asian hair, emphasizing the need for more comprehensive studies in this area.

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 article proposes a methodology for selecting hair extension technology that aligns with natural hair structure and aesthetic goals, suggesting the best results are achieved by matching technique to hair's mechanical capacity.

This review examines dandruff and seborrheic dermatitis, highlighting the role of Malassezia yeasts in inflammation and hyper-proliferation, and reports no new clinical findings.

Early-stage skin substitutes improve wound healing and skin structure.

This study found that dermal papilla and sheath cells can induce hair follicle formation in vitro and in vivo by interacting with hair follicle epithelial cells.

This study found that the molecular structure of hair is more sensitive to synchrotron X-ray radiation than its supramolecular architecture, indicating potential concerns for biological analyses using such radiation.

This study concluded that early-stage tissue-engineered skin substitutes, developed using skin progenitor cells, had a better graft efficiency and supported hair follicle formation, which may improve wound healing outcomes.

This study found that treating yak hair fibers with low-temperature plasma and microwaves weakened the scale structure and significantly improved dyeability.

This review examines the chemical composition and potential health risks of hair straighteners, but it reports no new findings and emphasizes the importance of understanding hair fibre structure for safe use.

This article reviews various diagnostic tools for hair disorders, describing methods ranging from invasive to noninvasive, but reports no new research findings or clinical results.
