This study observed that while hair density generally increased after PRP-based treatments for nonscarring alopecia, the extent of improvement and associated biomarker changes varied widely among individuals.

This study found that intralesional triamcinolone acetonide is more effective and faster than platelet-rich plasma in promoting hair regrowth for scalp alopecia areata.

In this case report, a 5-year-old boy presented with an itchy patch of hair loss in the frontotemporal region, with trichoscopy revealing specific hair shaft features, such as black dots and corkscrew hairs.

The examined study explored how trichoscopic evaluations of female pattern hair loss might relate to disease severity and histological changes, but the authors highlighted methodological issues such as unclear sample size determination and insufficient control of confounding variables, which limit the results' generalizability and reproducibility.

In this study, trichoscopy was found to enhance the early assessment of minoxidil therapy in males with pattern hair loss, leading to improved satisfaction and treatment compliance by revealing positive changes visible within one month.

This study observed that following hair transplantation, patients exhibited prominent perifollicular erythema and scaling one month after surgery, whereas by six months, accentuated follicular ostia and varying hair shaft abnormalities were consistently noted.

In this study, researchers observed that trichoscopy could reliably identify features such as anisotrichosis and signs associated with inflammation and fibrosis in female pattern hair loss, which may aid in assessing disease severity and guiding treatment decisions.

This study found that oral minoxidil was associated with short-term improvements in clinical severity for androgenetic alopecia, whereas oral dutasteride did not show significant early clinical changes in the six-month follow-up.

This study found that trichoscopy aided in assessing treatment responses for patchy alopecia areata, with both intralesional corticosteroids and platelet-rich plasma showing effectiveness, but only PRP significantly improved patient symptom impact scores.

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

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 case analysis found that trichoscopy is a valuable tool for diagnosing and monitoring treatment progress in tinea capitis by distinguishing between Microsporum and Trichophyton etiologies.

This study found that using the "Khalgai" hair care products enriched with copper and zinc for 28 days led to increased hair density, diameter, and follicular unit count in women, indicating improved hair morphology.

This study found that trichoscopy is highly effective for diagnosing different types of alopecia, showing an average diagnostic accuracy of 90–95%, with specific features aiding in differentiating forms like androgenetic alopecia and alopecia areata. New technologies and AI improve interpretation objectivity, suggesting expanded clinical integration.

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 review summarizes the clinical, trichoscopic, and histopathological features of alopecia types associated with cutaneous and systemic lupus erythematosus and explores their links to disease activity, but it reports no new clinical results.

This review highlights the various causes and treatment options for alopecia, noting that while non-scarring types often see successful hair regrowth, scarring forms require early intervention to manage inflammatory destruction of hair follicles.

This study aims to describe the trichoscopic pattern of chemotherapy-induced alopecia and its changes during different phases of chemotherapy.

This review discusses various nail changes in alopecia areata and suggests that they may be more prevalent than previously recognized, impacting quality of life and potentially indicating disease progression.

This article reviews current diagnostic methods and treatments for hair loss, including FDA-approved drugs and surgical options, but reports no new research findings.

This case report describes a 47-year-old man diagnosed with fibrosing alopecia in a pattern distribution, treated with clobetasol propionate and oral minoxidil while advised to avoid hair transplantation.

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.

In this study, researchers found that a low-cost USB dermoscope can effectively detect microscopic hair changes associated with early female pattern hair loss, making it a useful tool for diagnosis even without expensive equipment or programs.

In this study, researchers found significant associations between trichoscopic features and the severity of androgenetic alopecia in Korean participants, suggesting trichoscopy as a useful tool for early detection and monitoring by identifying indicators like vellus hairs and follicular unit changes.

In this institution-based randomized trial, oral betamethasone mini-pulse therapy for alopecia areata showed a faster therapeutic response compared to oral tofacitinib, as measured by trichoscopic changes and achievement of 50% hair regrowth.

This study suggests that male androgenetic alopecia and female pattern hair loss follow distinct progression pathways, characterized by different trichoscopic patterns related to hair diameter and follicular unit changes.

This study found that in patients with alopecia areata, trichoscopy was a valuable tool for monitoring disease activity, severity, and therapeutic response, showing changes in trichoscopic markers that preceded improvements observed in the hair pull test.

This study found that nonscarring alopecia in patients with systemic lupus erythematosus may indicate higher disease activity, as evidenced by specific histological and immunofluorescence changes.

In this prospective study, 15 patients with patchy alopecia areata treated with intralesional methotrexate every two weeks showed a significant improvement in hair regrowth and reduction in lesion severity, with changes linked to decreased tissue levels of TNF-α.

In this study, 45 patients with advanced basal cell carcinoma treated with the medication sonidegib experienced a 24% incidence of alopecia, with detailed trichoscopic and LC-OCT examination revealing specific hair changes, suggesting LC-OCT might help identify early signs of alopecia from sonidegib use.
