This article reviews monilethrix, a rare genetic hair disorder causing brittle hair and alopecia, and emphasizes the need for clinical diagnosis and characteristic tricoscopic findings.

This study suggests that a prototype device may accurately measure hair quantity, diameter, and density in balding patients, potentially aiding in diagnostic assessments, though formal clinical studies are needed to confirm its effectiveness.

In this study, the authors evaluated 200 Egyptian children with focal non-cicatricial alopecia, finding that alopecia areata (42%) and tinea capitis (40.5%) were the most prevalent causes. Trichoscopy identified unique features for each condition, enhancing diagnosis and management.

The trichometer accurately measures hair growth and is easy to use.

In this study, trichoscopic features aiding differential diagnosis of alopecia in Korean patients were found to be similar to those in Caucasians, but pigment pattern frequencies differed due to racial characteristics.

This review discusses trichoscopic features of hair disorders in individuals with dark skin phototypes and reports no new clinical results; the authors emphasize the need for more specific diagnostic criteria for these populations.

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.

This review covers current knowledge of tricoscopy's applications in diagnosing and monitoring scalp and hair disorders but presents no new clinical results.

This study found that trichoscopic examination in patients with androgenetic alopecia revealed that hair shaft heterogeneity was common, while the white peripilar sign and focal atrichia were associated with more advanced disease stages in both genders.

Trichoscopy is a helpful and quick method to identify different types of hair loss in women.

In this study, trichoscopic examination revealed that variations in hair diameter were more common in certain types of alopecia affecting the frontal scalp, suggesting the importance of evaluating the entire scalp for accurate diagnoses, although limitations include a single center design and small sample size.

Trichoscopy is a useful tool for diagnosing hair and scalp disorders.

This report highlights that trichoscopy is a useful, non-invasive tool for diagnosing tinea capitis in children, particularly in areas where lab facilities are limited.

This study found that trichothiodystrophic hair shows reduced and disoriented protein deposition in follicles, with both the cuticle and cortex affected, providing localized structural insights into keratin abnormalities.

This review details the use of trichoscopy for analyzing hair and scalp structures to differentiate between types of alopecia but does not report new clinical results.

This study reported that Trichoscan, a computer-assisted hair measurement system, was not supported as accurate for clinical trials due to errors in signal detection, despite its analysis speed.

This study developed a prototype device that suggests potential for diagnosing changes in hair quantity, diameter, and density, though formal clinical studies are needed to confirm these findings.

This abstract presents supplementary materials illustrating trichoscopy in alopecia areata and scarring alopecia using different dermoscopy techniques but reports no clinical findings.

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 concluded that exclamation mark hairs are the most reliable marker of disease activity in alopecia areata, with broken hairs, triangular hairs, and black dots also increasing the probability of active disease.

This review presents various trichoscopic findings for diagnosing alopecia areata but reports no new clinical results, emphasizing that no single marker is pathognomonic and multiple features should be considered together.

This review discusses the various trichoscopic features of androgenetic alopecia and alopecia areata, noting white dots in advanced cases as indicators of poor prognosis, but reports no new clinical results.

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.

In this study, trichoscopy was found to be an effective noninvasive tool for diagnosing female pattern hair loss at early stages, potentially eliminating the need for scalp biopsies.

This review discusses the use of trichoscopy for diagnosing alopecia and reports no new clinical results, emphasizing its role in identifying vascular and follicular features.

This study found that trichoscopy is highly effective for diagnosing different types of alopecia, showing an average diagnostic accuracy of 90–95%, with specific features aiding in differentiating forms like androgenetic alopecia and alopecia areata. New technologies and AI improve interpretation objectivity, suggesting expanded clinical integration.

Trichoscopy is a useful non-invasive method for diagnosing different hair loss conditions.

This study found that Follicular Maps, derived from trichoscopic images, remained consistent over time and unaffected by hair cycling or noncicatricial alopecia, offering a precise tool for diagnosing and monitoring hair and scalp conditions.

This study reported that Asian patients have few racial differences in trichoscopy compared to Caucasian patients, except for certain features like greater mean hair diameter and masking effects by normal skin color.
