This article discusses the uses and techniques of trichoscopy for hair and scalp disorders and reports no new clinical results.

This study suggests using a handheld dermatoscope may allow for simple and efficient differentiation of eruptive vellus hair cysts by detecting vellus hair shafts, as demonstrated in a familial case involving five women.

This study found that combining dermoscopy with reflectance confocal microscopy is more sensitive and specific than using either method alone for assessing vitiligo disease activity and treatment response. Additionally, specific characteristics observed via these techniques correlated with either good or poor treatment outcomes.

This study found that dermoscopy can identify typical features of Malassezia folliculitis, such as folliculocentricity and perilesional erythema, offering a valuable tool for diagnosing this condition in clinical settings.

This study suggests that a portable OCT system may be useful for the clinical diagnosis and evaluation of skin diseases and laser treatment outcomes.

This chapter reviews trichoscopic criteria and diagnostic features for various hair and scalp conditions, emphasizing their utility in non-invasive diagnosis, but reports no new clinical results.

This review examines the use of dermoscopy for diagnosing common hair disorders and highlights its importance, but it does not report new clinical results.

This study observed that specific dermoscopic features, such as altered pigmentary network and yeast invasion of hair follicles, along with certain histopathological features, assist in diagnosing pityriasis versicolor.

This review outlines the practical use of reflectance confocal microscopy in dermatology, detailing its applications and considerations for diagnosing various skin conditions, but reports no new findings.

This study found that dermoscopy is valuable for diagnosing facial actinic keratosis in Chinese patients, with specific patterns like red pseudonetwork and follicular plugs suggesting its utility in differential diagnosis.

This systematic review provides an in-depth evaluation of non-invasive imaging and biophysical methods for diagnosing and monitoring vitiligo, emphasizing the need for studies with larger sample sizes to verify their use in clinical practice and research.

Dermoscopy can help diagnose tinea capitis in children by looking for comma hairs, black dots, and broken hairs with white bands.

This review examines the role of dermatoscopy in cosmetic medicine and explores literature, training offerings, and practitioner utilization, but reports no new empirical findings.

This review examines hair shaft disorders, reporting limited evidence for treatments like minoxidil and oral retinoids, and emphasizes gentle hair care and genetic counseling for managing congenital cases.

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.

This study found that low-level laser therapy may reduce inflammation and increase hair thickness in patients with lichen planopilaris after six months of treatment, though the small sample size limits the findings.

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.

This study found that dermatologists in São Paulo reported increased confidence in teledermatology over one year, citing its utility for triage and diagnosis, particularly for superficial infections and pigmentary disorders.

This case report highlights the importance of early mycological diagnostics, supported by dermoscopy and ultraviolet-enhanced fluorescence dermoscopy, in preventing scarring from kerion celsi-associated hair loss in children.

This study found that handheld dermoscopes with polarized light can be beneficial in assessing treatment success in alopecia areata by revealing changes in trichoscopic features like thinning hairs and short terminal hairs.

This study involved using smartphone applications and low-cost trichoscopy devices to assess various hair and scalp conditions, with diagnoses confirmed through detailed imaging during remote consultations and in-person evaluations.

This study found that exogenous ochronosis from hydroquinone use in melasma treatment has distinctive dermatoscopic features that may aid in diagnosis without needing a biopsy.

In this study, dermoscopy was suggested as a potentially useful tool for improving the clinical recognition of pilomatricoma.

In this study, UVFD and sUVRD techniques revealed distinctive characteristics of GD lesions, suggesting that GD might be more common in younger individuals and females than previously thought, possibly due to underdiagnosis. Incorporating dermatoscopy in exams may help improve GD detection and management.

This study observed distinct dermoscopic features in pityriasis versicolor that could aid in its differentiation from similar skin disorders.

This article reviews the use of trichoscopy for diagnosing various types of alopecia and reports no new clinical results; it is suggested as a non-invasive method for diagnosis and monitoring treatment responses.

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 report highlights two cases where patchy alopecia developed after mesotherapy for androgenetic alopecia, indicating potential risks associated with this treatment.

This review discusses the use of trichoscopy in diagnosing and managing pediatric hair and scalp disorders and reports no new experimental findings.
