This review discusses diagnostic tools for scarring alopecias, emphasizing trichoscopy as a low-cost, non-invasive method for more accurate diagnosis, although it reports no new clinical results.

This review discusses the use of hair microscopy in diagnosing hair-related conditions, highlighting techniques and common applications, but presents no new experimental results.

This analysis concludes that while dermoscopy can aid in diagnosing tinea capitis, further research is needed to establish its independent diagnostic validity.

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 summarizes the main trichoscopic findings for diagnosing common hair and scalp disorders, but reports no new clinical results.

A man had an allergic reaction to minoxidil, which stopped after he discontinued use and started corticosteroids.

In this study, dermoscopic examination of COVID-19 patients revealed significant microvascular changes in the proximal nailfold, such as avascular areas and disorganized capillary architecture, compared to healthy controls, with some regression of these changes observed over time.

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 concluded that dermoscopy enhances the diagnostic capability for cicatricial alopecia beyond clinical inspection and identified novel dermoscopic features such as blue-grey dots.

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

This study suggests that while low-cost videomicroscopes can correctly identify hair shaft alterations, they may be unreliable for detailed follicular and perifollicular trichoscopic examination compared to standard videodermatoscopes.

This study found that dermoscopy-guided scalp biopsies provided a definitive pathological diagnosis in 95% of patients with cicatricial alopecia.

This article discusses the role of dermoscopy in identifying various hair loss conditions and recommends its use for improved diagnostic accuracy, particularly for distinguishing scarring from nonscarring alopecia and other similar conditions.

In this study, hair follicle effacement was identified as a key dermoscopic feature of cicatricial alopecia, and dermoscopy proved useful in distinguishing cicatricial from non-cicatricial alopecias.

This review updates on various methods for hair and scalp examination, encompassing non-invasive, semi-invasive, and invasive techniques, and reports no new results.

This study found that both reflectance confocal microscopy and optical coherence tomography can visualize detailed hair follicle abnormalities in various skin disorders, but larger, higher-quality studies are needed for clinical implementation.

This review discusses the use of trichoscopy as a valuable diagnostic and prognostic tool for various hair and scalp disorders, reporting no new clinical results.

This paper presents an RGB video microscopic system to monitor optical properties of hair shafts and follicles in vitro, but reports no new clinical results.

This study suggests that using ex vivo dermatoscopy can improve the accuracy of scalp biopsy processing by correctly guiding tissue bisection and potentially reducing laboratory costs and turnaround time.

UV-enhanced trichoscopy helps diagnose hair shaft disorders like pili annulati.

In this study conducted from September to November 2023, researchers used trichoscopy to accurately diagnose cicatricial alopecias by revealing unique patterns, reducing the need for biopsies, and proving to be a valuable non-invasive diagnostic method.

Dermatoscopy and videodermatoscopy are useful for diagnosing and monitoring various skin, hair, and nail conditions.

This study found that videodermoscopy enhances diagnostic accuracy for scalp and hair disorders beyond simple clinical inspection and reveals novel disease features that could improve clinical understanding.

In this study, pediatric hair and scalp disorders were effectively diagnosed using trichoscopic and light microscopic examinations, demonstrating high agreement with clinical diagnoses and emphasizing their utility as reliable, non-invasive diagnostic tools in a hospital-based setting.

In this study, researchers reported that dermatoscopy effectively differentiates between various types of alopecia and scalp disorders, offering a fast, minimally invasive diagnostic method that improves the standard of care and reduces the necessity for scalp biopsies.

This review summarizes trichoscopic features for diagnosing common hair loss disorders and reports no new clinical results, emphasizing their diagnostic utility in conditions like alopecia areata and trichotillomania.

This study reports that dermoscopy can improve the diagnosis of epidermal cysts by making small puncta visible, which are often missed during standard visual examinations.

The study suggests low-cost videomicroscopes may identify some hair shaft features but are unreliable for comprehensive scalp trichoscopy compared to standard devices, due to color and resolution limitations.

In this case study, trichoscopy was found to be a valuable non-invasive tool for diagnosing dissecting cellulitis of the scalp, enabling early detection and intervention to prevent disease progression and reduce the need for invasive procedures.
