This study shows that multiphoton microscopy can non-invasively distinguish between scarring and non-scarring alopecia by identifying certain morphological features, but further research is needed to confirm its clinical utility.

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 study reports that dermoscopy can improve the diagnosis of epidermal cysts by making small puncta visible, which are often missed during standard visual examinations.

This study observed that human hair keratin showed distinct morphological features depending on the dissolution speed, which could have potential applications in clinical settings for developing self-tendons.

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

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 article mentions that the slot correction technique by Dr. Patrick Frechet has been a valuable tool in the author's 100% hair restoration surgery practice but does not provide new clinical results.

This study examined the clinicopathologic and trichoscopic characteristics of keratosis follicularis spinulosa decalvans and identified terminal hair involvement and follicular hyperkeratosis as key diagnostic features.

This study found that trichoscopy is a useful tool for diagnosing and assessing the severity of alopecia areata and androgenetic alopecia in patients when visual diagnosis is challenging.

This case study describes a 14-year-old girl with pili annulati who had fragile hair, which may be due to cavities within the hair shafts as seen in electron microscopic examinations.

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

This article discusses patterns of female pattern hair loss in men but reports no new clinical results.

This article discusses patterned androgenic alopecia in normal women and reports no new clinical findings.

This case report describes the first observed instance of fibrosing alopecia in a pattern distribution in a child, suggesting the condition is not solely androgen dependent.

This study reported that fibrosing alopecia in a pattern distribution can occur in patients of color, with clinical and histopathological features allowing for an accurate differential diagnosis.

This study found that scanning electron microscopy with argon sputter etching visualizes hair lipids at the cell membrane complex as distinctive convex structures, shedding light on their role and localization in human hair.

Capitate trichomes have more endoplasmic reticulum and vacuoles, while peltate trichomes have more plastids and larger subcuticular spaces.

In this study, the researchers observed that male pattern alopecia is characterized by miniature follicles, enlarged sebaceous glands, and an increased number of mast cells, without significant abnormalities in enzyme activity.

The document concludes that diagnosing hair loss requires evaluating multiple histological features, as no single feature is definitive on its own.

This study found that ultraviolet-induced fluorescence trichoscopy can help differentiate between scarring and non-scarring alopecia and between psoriasis and seborrheic dermatitis.

This article reviews the use of trichoscopy for diagnosing various types of alopecia and reports no new clinical results; it is suggested as a non-invasive method for diagnosis and monitoring treatment responses.

In this study, researchers used three-dimensional reconstruction to show that the shape of the hair follicle determines the hair's form, with variations observed among different racial groups.

This review discusses the histopathology of male-pattern baldness and highlights ongoing disputes over several aspects, including sebaceous gland size and follicle loss, reporting no new clinical findings.

This review discusses the usefulness of trichoscopy in diagnosing and managing scalp and hair disorders, reporting it as a valuable tool for linking clinical and histological findings.

This study found that using ionic liquid for specimen preparation allowed for observation of dermal papilla cells and their cilia in near-living conditions, reducing damage typically caused by conventional preparation methods.

This study found that the occipital scalp is significantly involved in female pattern hair loss, with some patients showing clinically visible alopecia.

This study reported that trichoscopy revealed distinctive patterns across different autoimmune bullous diseases, suggesting it can be a useful preliminary diagnostic tool for differentiating these conditions.

The study suggests low-cost videomicroscopes may identify some hair shaft features but are unreliable for comprehensive scalp trichoscopy compared to standard devices, due to color and resolution limitations.

This study found no significant associations between dermoscopic findings and the severity or stage of alopecia areata in children, though there was a notable correlation with nail findings.
