This study observed that the keratinization pattern of trichilemmal cysts in two Japanese women may originate from the proliferation of the outer root sheath in the follicular isthmus of anagen hairs.

In this study, researchers analyzed hair from different regions of Malvi cattle and found significant variations in color, shape, and band pattern, although the medullary index remained consistent between 0.50 and 0.60 across the samples.

Proteomic analysis can identify genetic differences in mouse hair, helping understand hair defects and variations.

This article discusses Trikostazis spinuloza (TS), a dermatological condition often misdiagnosed, and reviews its demographic, clinical, and dermoscopic features, but reports no new clinical results.

This pilot study found that Optical Coherence Tomography can non-invasively resolve hair follicle density and hair shaft and follicle diameters in patients at varying stages of hair loss.

This study found that dermoscopic examination can significantly distinguish between female androgenetic alopecia and telogen effluvium based on hair diameter diversity and the presence of thin and vellus hairs.

Recognizing bamboo hair helps diagnose Netherton’s syndrome.

This study identifies specific trichoscopic features such as empty follicles and perifollicular erythema in Caucasians with frontal fibrosing alopecia, which may assist in diagnosis and monitoring, but stresses the need for further research due to limited demographic data.

This study suggests that immunohistochemistry of keratin and involucrin expression can aid in distinguishing malignant trichilemmoma from other tumors previously diagnosed as such.

This article explores the theoretical foundations of the ChromaLens Precision Mapping system for analyzing hair, but it does not present any new experimental findings.

This study found that pigmented vellus and upright regrowing hairs are the only predictive trichoscopic markers of hair regrowth in patients with alopecia totalis and universalis.

This letter discusses the use of serial trichoscopy versus a modified hair pull test for monitoring localized alopecia areata but reports no new clinical results.

This study found that psoriasis patients with scalp involvement had a significantly lower anagen ratio and higher telogen ratio compared to healthy individuals, indicating an association with an increased telogen/anagen ratio.

In this study, researchers found that using a handheld digital microscope, hair diameter was a better determinant of perceived alopecia severity in androgenetic alopecia than hair density.

This study found poor agreement among dermatopathologists in identifying and grading fibrosis in traction alopecia, suggesting the need for better diagnostic methods for early fibrosis detection.

This study reported that different types of alopecia have distinctive dermoscopic patterns, which aids in their diagnosis.

This case report describes a 4-year-old boy with Netherton syndrome, where trichoscopy importantly aided diagnosis and is recommended for all children with erythroderma.

This study reports that variation in the ovine TCHH gene may influence wool fibre curvature, with specific gene variants affecting the mean fibre curvature in sheep.

This study reported that trichoscopy can identify specific hair shaft abnormalities linked to increased serological activity, highlighting its use as a valuable non-invasive diagnostic tool in pediatric dermatology for neonates with ECS.

This article discusses the diagnostic challenges of evaluating hair and scalp conditions in patients using hair dye, emphasizing how dyes can mimic different pathologies and lead to contact dermatitis.

This study found that the HairCheck® device, demonstrating high correlation between its Hair Mass Index and hair characteristics such as strand number and diameter, may be an effective tool for assessing hair mass changes in alopecia patients.

This paper highlights trichodynia as a distinguishing symptom of telogen effluvium, but it does not present new clinical findings.

This case report describes how trichoscopy helped diagnose tinea capitis disguised as female pattern hair loss in cases of endothrix infection, highlighting its usefulness in avoiding misdiagnosis.

This case report highlighted two atypical childhood alopecia cases: congenital atrichia without papules and Bjornstad syndrome with alopecia areata; emphasizing diagnostic challenges, notably the absence of keratotic papules usually associated with congenital atrichia and the presence of alopecia areata in Bjornstad syndrome.

This pilot study detailed the use of Hair-to-Hair-matching technology™ in a clinical trial to assess botulinum toxin's efficacy in treating male androgenetic alopecia, providing a precise method for evaluating hair count and thickness changes over time.

This case study highlights how trichoscopy helped differentiate between diffuse alopecia areata and trichotillomania in an 11-year-old girl, demonstrating its importance in distinguishing hair disorders with similar presentations.

This review discusses the advantages and limitations of various hair loss evaluation methods but reports no new results; it emphasizes the importance of cautious interpretation for these diagnostic tools.

This study suggests that traditional classification systems for pattern hair loss, while useful in the past, have limitations in accuracy and reproducibility, and highlights the potential of integrating digital imaging and AI to create more precise and biologically informed classification frameworks.

This study found that in patients with patchy alopecia areata, certain trichoscopic features like upright regrowing hairs and pigtail hairs are positive predictive markers for treatment success.

This study found that polarized light microscopy is more effective than diffractive microscopy in distinguishing scarring from non-scarring alopecia, providing a highly specific adjunct diagnostic tool for alopecia biopsy specimens.
