This review evaluates various biopsy protocols for alopecia diagnosis and discusses the authors' experience with the St John's protocol but presents no new clinical findings.

This article reviews the complexities and challenges in hair transplant procedures, emphasizing the role of micro-inflammation and the usefulness of trichoscopy for detecting complications, and reports no new clinical results.

In this study, researchers documented several trichoscopic features that were statistically significant indicators of alopecia and scalp disorders compared to healthy controls.

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 article discusses managing extensive hair loss with limited transplant options and suggests a frontal forelock-type pattern is effective for both already bald men and younger patients at risk; it reports no new clinical results.

This study found that among Pakistani men with hair loss, the M type pattern was the most prevalent according to BASP classification.

This study observed that transverse sectioning of scalp biopsies may aid in diagnosing different types of alopecia by revealing distinct histopathological features like follicle miniaturization and specific inflammatory patterns.

This review discusses the role of trichoscopy in diagnosing and managing various alopecia types, highlighting its ability to detect specific patterns in both scarring and non-scarring forms, thus aiding in treatment decisions and reducing biopsy necessity.

This article introduces the term "anisotrichosis" to describe the significant variation in hair shaft diameters observed in pattern alopecia, drawing a parallel to anisocytosis seen in blood smears, but reports no new research findings.

In this study, trichoscopy significantly improved diagnostic accuracy in non-cicatricial alopecia, identifying alopecia areata as the most common cause and effectively aiding diagnosis in 28.2% of ambiguous cases.

In this study, LC-OCT imaging was found to noninvasively identify specific features of cicatricial alopecia due to lupus erythematosus, such as hyperreflective collagen fibers, which may aid in distinguishing it from other types of scarring alopecia.

This study found trichoscopy to be a quick and effective method for diagnosing and monitoring tinea capitis in children, with improvements in trichoscopic features observed by week 2 and full recoveries confirmed mycologically by week 8.

This review discusses recent advances in trichoscopy for differentiating types of alopecia and presents a systematic approach for using its diagnostic findings, but reports no new clinical results.

This study found that certain trichoscopic patterns, like exclamation mark hairs, were associated with active or mild alopecia areata in Turkish patients, aiding in diagnosis and prediction of the disease.

Comma hairs are a new sign for identifying scalp fungal infections.

This study identified specific trichoscopic features in patients with androgenetic alopecia and telogen effluvium, highlighting differences in hair shaft diameter variation between fronto-temporal and occipital areas.

In this study, the researchers found that scalp hair follicles affected by female pattern hair loss are poorly vascularized, likely affecting nutrient delivery, but capable of nutrient uptake when supplemented.

This study suggests that hormonal disturbances play a role in female pattern hair loss and that trichoscopy may be a useful tool for diagnosis and differentiation from other conditions.

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.

This study reported that Asian patients have few racial differences in trichoscopy compared to Caucasian patients, except for certain features like greater mean hair diameter and masking effects by normal skin color.

This article discusses trichoscopy as a tool for differential diagnosis in female-type androgenetic alopecia and reports on three patient cases without providing new clinical results.

In this study, trichoscopy was found to be helpful in diagnosing the types of noncicatricial alopecia, and alopecia's negative impact on quality of life was highlighted through the correlation with clinical severity.

This article discusses the trichoscopic diagnosis of temporal triangular alopecia, but reports no new clinical results.

This case report discusses cutaneous graft versus host disease presenting as fibrosing alopecia, suggesting a mechanistic model for understanding cicatricial pattern hair loss.

Tinea capitis can be quickly diagnosed and treated using dermoscopy to prevent hair damage.

This study found that in patients with non-cicatricial alopecia, hair follicles and their sheaths were thinner compared to controls, especially in cases of alopecia areata and telogen effluvium, with notable thinning beginning in the subcutaneous fat tissue.

This study reviews the diverse clinical presentations of tinea capitis, such as gray patches, a "black dot" appearance, and kerion, highlighting its complex differential diagnosis with conditions like alopecia areata and psoriasis.

Non-scarring hair loss can be diagnosed with two 4mm punch biopsies, one cut vertically and the other transversely.

This review discusses histologic findings in alopecia and emphasizes the importance of understanding normal follicular anatomy and cycles in transverse sections, without reporting new results.

Dermatoscopy helps diagnose hair and scalp disorders in people with Afro-textured hair, but more research is needed for better understanding and treatment.
