In this case report, a 30-year-old woman with scalp demodicosis experienced resolution of itching, hair shedding, and facial lesions after six weeks of topical metronidazole, highlighting the importance of early trichoscopic diagnosis and treatment for Demodex mite infestations.

This review highlights that diagnosing cicatricial alopecia, a hair loss condition linked to several autoimmune diseases, requires trichoscopy and histopathological examination to differentiate it from similar conditions, with early diagnosis being crucial for effective management.

In this study, trichoscopy was identified as a valuable diagnostic tool for alopecia areata, revealing that specific hair features like yellow dots and short vellus hairs help assess disease activity and phase, with diagnosis relying on multiple combined signs rather than a single indicator.

This study concluded that trichoscopy is an effective, non-invasive tool for diagnosing telogen effluvium, with significant differences in trichoscopic findings between frontal and occipital scalp regions, aiding in distinguishing it from androgenetic alopecia for early diagnosis.

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.

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.

In this review, the authors concluded that trichoscopy is a quick, non-invasive, and effective method for diagnosing and monitoring non-scarring alopecia, offering a more precise and faster alternative compared to other diagnostic methods for identifying and managing different types of hair loss.

This study found that trichoscopic examination in patients with androgenetic alopecia revealed that hair shaft heterogeneity was common, while the white peripilar sign and focal atrichia were associated with more advanced disease stages in both genders.

This study reports that normal scalp and hair in Black Africans exhibited regular white dots and a preserved honeycomb pattern, with some showing peripilar casts and scales.

This review discusses the role of trichoscopy in diagnosing lichen planopilaris and reports no clinical results; the authors emphasize early recognition to potentially prevent permanent scarring.

This review highlights the increasing use of trichoscopy, a noninvasive and well-tolerated diagnostic tool, to aid in the accurate diagnosis and management of various pediatric hair and scalp conditions, such as alopecia and other abnormalities.

This study examined trichoscopic findings in androgenetic alopecia, reporting that hair diameter variability, vellus hairs, and the peripilar sign are valuable indicators for diagnosing this condition.

This study found that trichoscopy is an effective method for monitoring treatment response in androgenetic alopecia when conducted by doctors experienced in hair diseases, showing excellent agreement with TrichoScan measurements for various hair parameters.

This study aimed to document and compare the prevalence and characteristics of hair loss in patients with systemic lupus erythematosus, noting the differences in trichoscopic and histopathologic evaluations between those with and without alopecia. Results are not reported.

This study found that trichoscopic examination can effectively differentiate between alopecia areata and trichotillomania, as specific features such as black dots and exclamation marks favor alopecia areata while hair breaking at various lengths and several unique patterns are exclusive to trichotillomania.

This retrospective study conducted at two centers in west Mexico identified distinctive trichoscopic features in pediatric androgenetic alopecia, with 70% of patients being male and most showing vitamin D deficiency; topical minoxidil was effective and well-tolerated as a treatment.

In this case report, trichoscopy was highlighted as a vital diagnostic tool for pediatric alopecia areata, showing significant hair regrowth in a 4-year-old girl with toxoplasma-related alopecia after six weeks of therapy, emphasizing its role in tracking therapeutic progress.

This review presents European expert guidelines for diagnosing androgenetic alopecia across genders but reports no new clinical findings; it emphasizes the importance of trichoscopy for differentiating similar conditions.

This descriptive longitudinal study conducted in a Kolkata hospital found that intense pulsed light treatment significantly improved hirsutism in patients, as evaluated by trichoscopy and visual analog scores, demonstrating its effectiveness and safety for hair removal, independent of medical treatment.

This study developed a support vector machine model using trichoscopic patterns to accurately classify androgenic alopecia severity, with an accuracy of 94.3% in training and 90.0% in test datasets.

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.

In this retrospective study, researchers from the University of Bologna observed that trichoscopy can aid in diagnosing allergic scalp contact dermatitis, with key findings including common trichoscopic patterns of erythema, white scales, arborizing vessels, and simple red loops in 12 patients diagnosed with the condition.

This study found that both trichoscopy and folliscopy are highly accurate for diagnosing telogen effluvium, but trichoscopy is easier and quicker to perform.

Trichoscopy is effective in diagnosing trichotillomania by showing specific hair patterns.

The researchers in this study described the use of trichoscopy to assist in diagnosing aplasia cutis congenita of the scalp in a dark-skinned newborn, noting that trichoscopic findings can differ from those seen in light-skinned patients, yet remain a valuable diagnostic tool.

This study found that vitamin D levels were lower in alopecia areata patients, with trichoscopic features like broken hairs and black dots more prevalent in cases with vitamin D deficiency.

This study concluded that trichoscopy is a reliable, non-invasive, and faster diagnostic method for ambiguous cases of alopecia.

This study examined 50 patients with alopecia areata and found that trichoscopy can identify specific patterns, such as white dots in 90% of cases and black dots in 80%, aiding in assessing disease activity and severity without invasive procedures.

This study observed that trichoscopy can identify specific patterns in alopecia areata, such as white and black dots, which assists in non-invasive diagnosis and assessing disease severity.

This study found that both trichoscopy and folliscopy are highly accurate for diagnosing telogen effluvium, though trichoscopy is simpler and faster to perform.
