In this study, patients with Alopecia Areata showed significant clinical improvement after intralesional steroid treatment, as trichoscopic features like black dots and exclamation mark hairs decreased, while short vellus and circle hairs increased, highlighting Trichoscopy's utility in monitoring treatment response.

This study found that RCM combined with dermoscopy can differentiate disease states between alopecia areata, tinea capitis, nevus sebaceous, and linear scleroderma of the scalp by identifying distinct dermal and follicular patterns.

This article reviews the use of dermoscopy as a noninvasive tool for diagnosing various types of nonscarring alopecia but presents no new clinical findings.

This article discusses trichoscopy as a tool for differential diagnosis in female-type androgenetic alopecia and reports on three patient cases without providing new clinical results.

This report suggests a possible association between temporal triangular alopecia and sebaceous nevus, and identifies a pinkish background as a new trichoscopic finding for TTA.

This article reviews the use of dermoscopy in distinguishing temporal triangular alopecia from alopecia areata, emphasizing its role in avoiding invasive diagnostics and ineffective treatments; it reports no new clinical findings.

In this study, optical coherence tomography was used to produce 3D images of human hair, revealing that after chemical treatment with ammonium thioglycolate, the main hair structures were not identifiable due to damage.

This study developed a deep learning framework and quantitative model that accurately predict basic and specific classification in male androgenetic alopecia by analyzing trichoscopic images.

In this study, researchers found that a low-cost USB dermoscope can effectively detect microscopic hair changes associated with early female pattern hair loss, making it a useful tool for diagnosis even without expensive equipment or programs.

This study reports two cases of trichoblastic neoplasms with histologic features suggesting they may be distinct, locally aggressive trichoblastic carcinomas separate from basal cell carcinoma.

This review discusses the diagnostic features of androgenetic alopecia through trichoscopy and reports no clinical results; it emphasizes hair shaft variability and yellow dots as key indicators.

In this study, the authors emphasize the importance of not ignoring the partial presence of comma or harpin hairs and black spots when identifying early lesions of tinea capitis, which may initially be overlooked due to their small size.

This study observed that videodermoscopic assessments of dermatomyositis patients revealed specific vascular and pigmentary features, suggesting it may be useful for preliminary diagnosis.

This study highlighted that diagnostic complexities can lead to misdiagnosis of alopecia areata in Black patients, commonly due to similar presentations of scarring alopecias and multiple hair loss types co-occurring within a single patient.

This study measured the force required to pluck anagen and telogen hair from volunteers, suggesting that trichotillometry could assess hair strength in alopecia patients and evaluate treatment efficacy.

This study found that human hair shows more susceptibility to perforation by Trichophyton mentagrophytes and Trichophyton verrucosum compared to animal hair, with black human hair serving as a reliable diagnostic tool for differentiation between the two species.

The study found that Temporal Triangular Alopecia often starts in early childhood, while Folliculitis Decalvans is characterized by tufted hairs and redness around hair follicles.

In this study, trichostasis spinulosa was observed in 51 patients with lesions on the nose, where some follicles contained up to 86 hairs each, possibly influenced by endocrine factors and actinic rays.

Trichoscopy is a helpful and quick method to diagnose hair loss without shaving.

This study observed that indigenous South Africans with natural afro-textured hair have lower hair densities, varying shaft diameters, and distinct follicular unit patterns compared to other racial groups, with significant gender differences in some parameters, highlighting the need for tailored reference values in clinical settings.

This study investigated the hair of German shepherd dogs, revealing variations in color, shape, and band patterns across different body regions, while all hair types shared similar anatomical structures such as continuous, vacuolated medullas and cuticular scales with smooth or rippled margins.

This study observed that temporal triangular alopecia in infants presents with distinct clinical and dermatoscopic features, indicating the usefulness of dermatoscopy for diagnosis and differential diagnosis.

This review discusses the characteristic trichoscopy patterns useful in differentiating lichen planopilaris and frontal fibrosing alopecia from similar conditions but reports no new clinical results.

In this scoping review, researchers observed that while AI-assisted trichoscopy holds promise for standardized assessments of hair and scalp disorders, its clinical translation is limited by small proprietary datasets, inconsistent validation protocols, and a scarcity of real-world clinical studies.

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

This article discusses phototrichogram education and patient satisfaction in androgenetic alopecia but reports no new clinical findings.

In this study, hair shafts from trichothiodystrophy patients with ERCC2 mutations revealed abnormal cuticle structures and protein imbalances compared to normal hair shafts.

This study identified genetic variants in the Trichohyalin gene that account for approximately 6% of the variance in hair morphology among Australians of European descent.

This study employed a laser-based method to analyze how light reflection patterns vary on human hair fibers, revealing changes related to hair color and the tilt of the cuticle cells.
