In this study, researchers developed a machine learning model that accurately diagnosed scalp conditions like fine dandruff and perifollicular erythema with 75% and 82% accuracy, respectively, and created a user-friendly web platform for scalp health self-assessment, which achieved high user satisfaction.

In this study, a modified Xception deep learning model achieved a 92% accuracy rate in diagnosing hair and scalp disorders, significantly outperforming other models, suggesting AI could improve dermatological diagnostics' accuracy and accessibility.

This article reviews prominent variants of scalp hair folliculitis and their differential diagnosis, but reports no new clinical findings.

This study highlights the complexity of diagnosing scalp fungal infections, emphasizing how clinical evaluation, trichoscopy, and cultural samples are essential in distinguishing tinea capitis from similar conditions like piedra, seborrheic dermatitis, and psoriasis, due to overlapping symptoms like scaling and hair changes.

This case report describes a 15-year-old boy who experienced severe allergic contact dermatitis from hair dye, highlighting the importance of identifying allergens through patch testing.

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 horizontal sections of scalp biopsy specimens provide more diagnostic information for male pattern androgenetic alopecia than vertical sections and can predict hair regrowth potential following topical minoxidil therapy.

Biopsies matched initial diagnoses in 76.6% of black women with alopecia and led to treatment changes in 44% of cases.

In this study, transverse sectioning of scalp biopsy samples showed higher diagnostic accuracy than vertical sectioning for noncicatricial alopecia, although both techniques are important for accurate diagnosis.

This review discusses the epidemiology, risk factors, clinical features, and management of scalp melanomas, highlighting their high mortality rates and specific challenges in diagnosis and treatment; it reports no new research findings.

This study reports that deep learning models, particularly CNN and FCN, achieved high accuracy in diagnosing scalp and skin disorders, suggesting potential for improved diagnostic systems with further advancements.

This study concluded that including intermediate hairs or using relative shaft diameter methods can significantly improve the sensitivity of trichograms in diagnosing female androgenetic alopecia, aligning better with histopathology results.

This systematic review reports that trichoscopy is highly accurate for diagnosing scalp disorders, suggesting it as a valuable alternative to biopsies and supporting recommendations for its integration into routine dermatology practice.

This review discusses the classification and diagnosis of primary scalp alopecia, focusing on scarring and non-scarring types, and reports no new clinical results; it emphasizes simplified diagnostic pathways and tissue processing techniques.

This review reports that while deep learning shows promise in diagnosing scalp disorders from images, challenges remain with data quality and model interpretability, suggesting that integrating explainable AI techniques is crucial for building trust and facilitating clinical adoption.

This study investigated the use of scalp biopsies for diagnosing and managing alopecia in Black women, focusing on distribution, prevalence, and biopsy outcomes, but did not report new clinical results.
