In this study, certain trichoscopic features were found to be sensitive and specific for diagnosing primary cicatricial alopecias and its subtypes using dermatoscopy.

This study reported that polarized dermoscopy was better for visualizing vascular patterns, scaling, and reticular pigmentation, while nonpolarized mode better documented features like black dots and tapered hair in various hair and scalp conditions.

This article reviews trichoscopic signs of chemotherapy-induced alopecia, including exclamation marks, but reports no new clinical results.

This study observed that orange spots and dystrophic hairs on trichoscopy may aid in diagnosing scalp sarcoidosis.

This study is the first to describe a mixed pattern of essential syphilitic alopecia using trichoscopy, identifying features like tapered bended hairs and perifollicular hyperkeratosis in a patient without secondary syphilis symptoms.

This study found that trichoscopy can rapidly and noninvasively diagnose tinea capitis and alopecia areata in pediatric patients by identifying specific hair patterns associated with each condition.

This study found that in the Thai population, hair density varies by scalp location and decreases with age, and that Asians generally have lower hair density compared to Caucasian and African populations.

The study observed that Americans of Hispanic descent have a statistically significant higher hair density than individuals of African descent but lower than Caucasians, which may assist in diagnosing and researching hair disorders.

This study found that certain trichoscopic features like white peripilar sign, yellow dots, and scalp pigmentation are positively correlated with the severity of androgenetic alopecia in Chinese patients.

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 abstract suggests that specific trichoscopic features like black dots, coiled hair, and trichoptilosis may help differentiate trichotillomania from patchy alopecia areata.

This study found that trichoscopic examination is useful for diagnosing and monitoring systemic lupus erythematosus, with severe diffuse non-scarring alopecia indicating active disease.

This case study highlights the importance of considering syphilis in the differential diagnosis for hair loss, as patients with the infection may present with non-typical alopecia patterns.

This article discusses various aspects of trichoscopy for diagnosing hair and scalp disorders and reports no clinical results, offering guidance and highlighting pitfalls for better application of this tool by dermatologists.

This study observed that specific trichoscopic features like white peripilar signs, scalp pigmentation, and focal atrichia are associated with advanced female pattern hair loss in Fitzpatrick skin type III patients.

This study aimed to identify trichoscopic features that help differentiate between tinea capitis and alopecia areata in children, enhancing diagnosis and treatment decisions visually and non-invasively.

This study found that certain trichoscopic patterns, like exclamation mark hairs, were associated with active or mild alopecia areata in Turkish patients, aiding in diagnosis and prediction of the disease.

Trichoscopy helps diagnose and manage different types of hair loss effectively.

This study suggests that trichoscopy with a handheld dermatoscope may help differentiate temporal triangular alopecia from other localized alopecia by identifying specific hair features.

This study analyzed the features of alopecia areata incognita and diffuse alopecia areata, finding distinct patterns in hair loss regions and trichoscopic signs, and noted a benign course responsive to topical steroid therapy.

This study describes a distinct pattern of trichoscopic features associated with chemotherapy-induced alopecia and how these features evolve through different phases of chemotherapy treatment.

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

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.

This case report describes a 57-year-old Japanese female who developed scarring alopecia linked to gefitinib, an EGFR inhibitor, with improvement in hair loss after reducing the drug dosage.

This report on two Indian male siblings with monilethrix highlights trichoscopy's role in diagnosing this condition, which can be complicated by early-onset androgenetic alopecia.

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 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 study, trichoscopy consistently identified typical findings of frontal fibrosing alopecia, revealing three unusual clinical patterns in 18.4% of patients, which may aid in the differential diagnosis when clinical presentations are atypical.

This study identified distinctive trichoscopic features that may aid in diagnosing loose anagen hair syndrome, such as rectangular black granular structures, solitary yellow dots, and a predominance of follicular units with single hairs.

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.
