This review discusses the use of trichoscopy for diagnosing systemic diseases and concludes that certain trichoscopic features may help dermatologists suspect these conditions.

This study found that trichoscopy has limited value for diagnosing telogen effluvium, as common findings are not specific enough to differentiate it from other conditions like androgenetic alopecia.

This study reviews the use of trichoscopy in diagnosing and monitoring alopecia areata, highlighting that certain trichoscopic findings like yellow and black dots, exclamation mark hairs, and others, provide valuable insights into disease status and treatment response.

In this study, researchers investigated the alignment of trichoscopic findings with ayurvedic signs (lakshanas) for diagnosing hair loss, suggesting that integrating these perspectives could enhance diagnostics and management of hair and scalp conditions.

This study introduces a novel non-invasive method called "differential stripping" to quantify the penetration of topically applied substances into hair follicles.

Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.

This study found that due to variability in measurements, hair pluckability is not a reliable indicator of adult nutritional status, although it may hold potential in certain emergency situations if improved for consistency.

This article reviews the role of trichoscopy in diagnosing hair weathering conditions like trichorrhexis nodosa and trichoptilosis and suggests treatment by avoiding harmful chemical and physical factors, but it provides no new research findings.

This study suggests that RCM may be a promising non-invasive diagnostic tool for alopecia areata incognita, showing substantial agreement with histopathology while noting some discrepancies.

This study found that trichoscopy aided in assessing treatment responses for patchy alopecia areata, with both intralesional corticosteroids and platelet-rich plasma showing effectiveness, but only PRP significantly improved patient symptom impact scores.

Understanding hair structure and growth is key for diagnosing hair diseases accurately.

This study introduced a new high-throughput method for analyzing scalp hair morphology and found that quantifying hair form provides more accurate information than traditional classification based on racial categories, challenging the belief that cross-sectional morphology predicts hair curvature.

This review discusses the dermoscopic features of common hair and scalp disorders and reports no new clinical results, aiming to assist dermatologists in diagnosing conditions like tinea capitis and alopecia areata.

This review discusses recent advances in noninvasive hair imaging technologies, such as global photography, trichoscopy, reflectance confocal microscopy, and optical coherence tomography, highlighting their potential to improve hair diagnostics and treatment monitoring, while also outlining their clinical applications and limitations.

This article reviews confocal microscopy findings in trichoepithelioma and desmoplastic trichoepithelioma, noting similarities with histological features, but it provides no new clinical results.

This study observed that white dots, focal atrichia, and honeycomb pigmentation on the scalp were significantly associated with the severity of androgenetic alopecia in men under forty.

This study concluded that among the three diagnostic techniques for detecting Demodex mites in dogs, the scraping technique provided the best diagnostic value.

This study describes a simple, noninvasive hair counting method used in a hair growth prevention trial, assessing its reliability and validity.

This study used electron microscopy to characterize tissues on telogen hair roots, finding that tissue quality, including nucleated and nonnucleated epithelial cells, may play a crucial role in DNA typing for forensic analysis.

In this retrospective study, researchers from the University of Bologna observed that trichoscopy can aid in diagnosing allergic scalp contact dermatitis, with key findings including common trichoscopic patterns of erythema, white scales, arborizing vessels, and simple red loops in 12 patients diagnosed with the condition.

In this case study, a 74-year-old woman improved her scalp hair condition by reducing chronic rubbing, leading to hair regrowth without ongoing abnormalities after behavior modification.

This paper introduces an algorithm for using smart device-mounted microscopes to analyze scalp images and diagnose hair loss by extracting specific hair loss features.

This study found a strong correlation between the Sinclair Scale and cumulative hair thickness density, allowing the estimation of the Sinclair Scale from trichoscopy-derived statistics.

This study found that trichoscopy can confirm the diagnosis and assess the clinical severity of female androgenetic alopecia, correlating specific features with different severity grades.

This study identified specific trichoscopic features in patients with androgenetic alopecia and telogen effluvium, highlighting differences in hair shaft diameter variation between fronto-temporal and occipital areas.

This study found that dermoscopy is effective for distinguishing Tinea Capitis from Alopecia Areata by identifying unique trichoscopic features specific to each condition.

This article discusses the role of trichology in treating hair and scalp conditions by addressing underlying body systems and reports no new clinical findings.

In this study, trichoscopy was found to be helpful in diagnosing the types of noncicatricial alopecia, and alopecia's negative impact on quality of life was highlighted through the correlation with clinical severity.

This study developed new graded visual scales integrating macroscopic and trichoscopic images for assessing the severity of androgenetic alopecia in men and women, potentially aiding in more objective disease evaluation.
