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

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

This study found that a peripilar white gray halo around hair emergence is a highly specific and sensitive dermatoscopic feature for diagnosing central centrifugal cicatricial alopecia in African American patients with mild central thinning.

This study found that dermoscopy is an effective tool for diagnosing and monitoring androgenetic alopecia in women, as it helped identify common signs such as hair miniaturization and peripilar brown halo.

This study found that thermal hair straightening in Asian women was associated with various signs of scalp and hair damage, including CCCA-like hair loss.

This chapter reviews trichoscopic-pathologic correlations in Frontal Fibrosing Alopecia and reports no new clinical results; the authors discuss genetics, clinical patterns, and unusual variants associated with this condition.

This study found that dermoscopy of the axilla in patients with frontal fibrosing alopecia revealed significantly higher odds of brownish peripillary halos, suggesting a diagnostic clue for the condition in this region.

This study identified a new variety of central centrifugal cicatricial alopecia that includes patchy hair loss on the lateral and posterior scalp in African-American women, which could be misdiagnosed as traction alopecia without dermatoscopy and pathology.

This article discusses features, genetics, and diagnostic challenges of central centrifugal cicatricial alopecia in African American women but reports no new clinical results.

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 peripilar signs on the scalp are linked to perifollicular lymphocytic infiltrates in early androgenetic alopecia, detectable even in areas with high hair density.

This study observed that trichoscopic patterns, such as yellow dots and honey comb patterns, correlate with the severity of androgenetic alopecia in Indian patients, highlighting trichoscopy's diagnostic and prognostic value.

This study reported that trichoscopy is a more effective diagnostic tool than the trichogram for early diagnosis of FAGA, regardless of hair shaft diversity cut-off levels.

This review covers trichoscopy's role in diagnosing scalp disorders, emphasizing its potential to improve clinical accuracy, but it reports no new clinical results.

This study found a significant discordance between clinical symptoms and dermatoscopic signs with histopathological inflammation in patients with LPP and AFF, affecting diagnostic and therapeutic approaches.

This study concluded that a polarized-light handheld dermatoscope attached to a digital camera is a practical and useful tool for diagnosing different types of alopecia.

This review examines the use of dermoscopy for diagnosing common hair disorders and highlights its importance, but it does not report new clinical results.

This study found that a family history of androgenetic alopecia and specific trichoscopic signs are strong predictors of female pattern hair loss, leading to a nomogram model for risk prediction.

In this observational study, researchers found that acute telogen effluvium, a form of temporary hair loss, occurred in 80 patients following COVID-19 infection, with 70 showing a significant decrease in hair density and trichoscopic signs like peripilar sign and yellow dots.

In this study, researchers evaluated trichoscopy in diagnosing non-scarring alopecia and found diagnostic value in observing diverse hair diameters in androgenetic alopecia, black dots and broken hairs in alopecia areata, and empty follicles in telogen effluvium, supporting trichoscopy's utility in differentiating alopecia types.

This study reported that different types of alopecia have distinctive dermoscopic patterns, which aids in their diagnosis.

This study found that certain trichoscopic features like white peripilar sign, yellow dots, and scalp pigmentation are positively correlated with the severity of androgenetic alopecia in Chinese patients.

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.

This review discusses the diagnostic features of androgenetic alopecia through trichoscopy and reports no clinical results; it emphasizes hair shaft variability and yellow dots as key indicators.

This case report describes a unique presentation of frontal fibrosing alopecia characterized by a hair loss pattern that resembles the Greek letter upsilon, supported by trichoscopic and histological findings.

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.

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 trichoscopy revealed significant differences in certain variables, such as the brown peripilar sign and white peripilar sign, which may aid in diagnosing early and late stages of androgenetic alopecia.

In this study, trichoscopy was found to be an effective noninvasive tool for diagnosing female pattern hair loss at early stages, potentially eliminating the need for scalp biopsies.

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.
