This article reviews trichoscopic techniques for diagnosing common hair loss conditions and presents a revised algorithm for identifying specific features of cicatricial and noncicatricial alopecia, but reports no new clinical results.

This review addresses the complexities in trichoscopy terminology and proposes an updated diagnostic flowchart for hair diseases, but it reports no new clinical findings.

A teenager's hair with alternating white and dark bands, known as Pili annulati, is a genetic condition that is usually harmless and often considered attractive.

This study suggests a potential role for systematic scalp examinations in first-degree relatives of patients with pattern cicatricial alopecia.

This review discusses trichoscopic features of hair disorders in individuals with dark skin phototypes and reports no new clinical results; the authors emphasize the need for more specific diagnostic criteria for these populations.

This review discusses the various trichoscopic features of androgenetic alopecia and alopecia areata, noting white dots in advanced cases as indicators of poor prognosis, but reports no new clinical results.

This abstract discusses clinical techniques for diagnosing female pattern hair loss and reports no new research findings.

In this study, chemotherapy-induced alopecia in cancer patients showed specific trichoscopic patterns and abnormal hair shaft morphology, suggesting intermittent follicle damage from chemotherapy, but larger studies are needed for confirmation.

This study reports that congenital triangular alopecia, which can be misdiagnosed as other conditions, lacks effective treatment and generally requires no therapeutic intervention.

In this study, sweat duct differentiation was found to be a rare feature in trichilemmal cysts, occurring in only 0.97% of cases, and was likely under recognized.

This article discusses ideal techniques for harvesting donor tissue in hair restoration surgery but reports no new clinical results.

This article is a letter to the editor about fibrosing alopecia in a pattern distribution and reports no new research findings.

This review discusses congenital temporal triangular alopecia, focusing on its clinical presentation and dermatoscopic diagnosis, and highlights the limited understanding of its etiology and treatment options; it reports no new clinical results.

This study found that Trichoscope can effectively reveal clinical features of alopecia areata and androgenic alopecia, making it a useful tool for diagnosis and monitoring.

In this study, a dog with canine pattern alopecia showed improved multifocal alopecia and general hair regrowth after 3 months of melatonin treatment.

In this study, researchers developed a mathematical model of outer hair cell hair bundles that replicates experimental responses to mechanical stimuli, providing insights into the stimulus-dependent adaptation mechanisms and the functional significance of their three-row stereocilia configuration in mammalian hearing.

In this study of a TRPS type I patient, many genes related to keratin and hair development were down-regulated in balding scalp areas, providing new insights into TRPS and hair morphogenesis.

This review discusses the characteristics and diagnostic challenges of fibrosing alopecia pattern distribution, proposing an algorithm for hair transplantation, but reports no new clinical results.

This study reports a unique case of trichotillomania incognita in an adult female that mimicked female pattern hair loss, highlighting the importance of trichoscopy and histology for accurate diagnosis.

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.

This study suggests that varying intersheet interactions may explain the differences between the two polymorphic forms of macrofibril assembly in Merino wool and hair.

This study found that histopathologic features such as a catagen/telogen shift, melanin in fibrous tracts, and small dystrophic follicles can help differentiate alopecia areata from pattern hair loss in the absence of peribulbar infiltrates.

This article discusses the temporo-parieto-occipital flap for scalp reconstruction and reports no new clinical results; the authors emphasize its specific reconstructive indications.

This study observed that white females with Ludwig I female pattern hair loss had higher hair density on the occipital scalp, whereas Asian females had thicker hair diameters in both frontal and occipital areas.

In this study, trichoscopy revealed hair shaft abnormalities similar to those seen in alopecia areata and chemotherapy-induced alopecia in patients over 12 months following hair restoration surgery.

This study found that multi-hair follicles naturally orient perpendicular to the radial line from the crown whirl, suggesting that perpendicular transplantation of grafts could replicate this natural appearance.

This review details the use of trichoscopy for analyzing hair and scalp structures to differentiate between types of alopecia but does not report new clinical results.

The man's occipital hair loss was due to temporal triangular alopecia, not alopecia areata.

This case report describes a 54-year-old man diagnosed with fibrosing alopecia in a pattern distribution, presenting with follicular inflammatory lesions and scleroatrophy on the scalp.
