Phototrichogram helps assess hair loss severity.

In this observational study, researchers found that alopecia areata is associated with specific trichoscopic features, such as black dots, yellow dots, and vellus hair, and highlighted trichoptilosis as a potential overlap feature with other hair disorders, suggesting a need for further differentiation between these conditions.

This study found that the TrichoScan method for evaluating hair loss showed excellent correlation with manual marking and provided more consistent, reproducible results with less variability and operator error.

This study observed that trichoscopic changes associated with EGFRI treatment include pili torti and asymmetric hyperpigmented fusiform widening, along with dermoscopic skin manifestations such as scale and branching vessels.

This study found that trichoscopy can effectively identify specific patterns associated with Vitamin B12, Vitamin D3, and serum ferritin deficiencies in patients with Telogen Effluvium, offering a non-invasive alternative to blood tests for early diagnosis and management.

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 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 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 study found that quantitative trichoscopy is a simple and effective method for determining hair density and thickness in Egyptians, establishing baseline values for clinical hair loss investigations.

This case report highlights the importance of trichoscopy in diagnosing fibrosing alopecia in pattern distribution, distinguishing it from female pattern hair loss, and guiding effective treatment.

This study identified black dots as the most common trichoscopic sign in children with alopecia areata, which is crucial for diagnosis and understanding disease severity and prognosis.

In this study, no significant association was found between the severity of androgenetic alopecia in males and trichoscopy features such as hair diameter diversity, vellus hair, and white dots, suggesting that trichoscopy may not predict alopecia severity based on the Hamilton–Norwood scale.

This study found that female pattern hair loss and acute telogen effluvium have distinct trichoscopic and histochemical characteristics, which may aid in their diagnosis and differentiation.

This study analyzed dermoscopic findings in alopecia areata among children and adults, discovering that exclamation mark hairs are more common in children, while yellow dots appear more often in adults, indicating the importance of age-specific evaluation in diagnosing this condition.

In this study, trichocytes were shown to have potential for alternative differentiation, with mesenchymal cell influences playing a critical role in determining this process.

A deep learning model was developed to help diagnose trichothiodystrophy by analyzing hair patterns.

This study found that trichoscopy using anisotrichosis criteria was 75% sensitive and 61.54% specific in diagnosing early female pattern hair loss in women without visible hair thinning.

This study associated ivory-colored areas observed through trichoscopy with steroid deposits in the dermis among patients with steroid-induced atrophy on the scalp.

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.

The study found that Temporal Triangular Alopecia often starts in early childhood, mainly affects the left side of the scalp, and has no effective treatment except surgery.

This study found that trichoscopy is a valuable diagnostic tool for identifying hair loss patterns in women and can help avoid scalp biopsies in unclear cases.

This study suggests that chemical methods can reveal subtle differences in scalp hair color variability across populations and emphasizes the need for enhanced understanding of hair fiber 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.

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 discusses the evolution and potential of non-invasive imaging techniques for diagnosing scalp diseases, highlighting their advantages and limitations compared to trichoscopy and scalp biopsy, the current diagnostic standards.

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 study found that the modified wash test was generally more effective than TrichoScan® for diagnosing hair loss, particularly telogen effluvium, though both methods showed only fair concordance with clinical diagnosis.

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.

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.
