This study found that trichoscopy criteria can distinguish female androgenic alopecia from chronic telogen effluvium, with specific features achieving 98% diagnostic specificity.

This study found that overexpression of miR-214 in keratinocytes inhibits hair follicle development and cycling by targeting β-catenin in the Wnt signaling pathway.

This review outlines the classification, histopathologic presentation, and pathogenetic concepts of scarring and nonscarring alopecias, reporting no new clinical results and emphasizing the need for clinicopathologic correlation.

This review presents various trichoscopic findings for diagnosing alopecia areata but reports no new clinical results, emphasizing that no single marker is pathognomonic and multiple features should be considered together.

This article reviews recent advancements in understanding and treating androgenetic alopecia, focusing on new genetic insights, stem cell roles, and diagnostic tools, without reporting new clinical results.

Trichoscopy is a useful non-invasive method for diagnosing different hair loss conditions.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

This review discusses trichoscopy as a noninvasive, effective technique for diagnosing various hair loss conditions and monitoring treatment, highlighting its potential to reduce scalp biopsy necessity.

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 study identified 63 genetic loci associated with male-pattern baldness, uncovering genes and pathways that may help develop treatments and suggesting its connection to other human conditions.

This study found that platelet-rich plasma was more effective for treating alopecia areata than topical 5% minoxidil, leading to earlier hair regrowth and reduction in hair abnormalities.

This review discusses the causes and diagnosis of traction alopecia, emphasizing education for high-risk populations as there is currently no cure, and presents no new clinical findings.

In this study, researchers observed that hyperandrogenic PCOS patients exhibited distinct miRNA and TGFβ signaling gene expression patterns in granulosa cells, suggesting these factors may play a role in PCOS pathogenesis.

This review offers evidence-based recommendations for diagnosing and treating female pattern hair loss, emphasizing clinical assessment and starting treatment with minoxidil, while noting that measurement of certain hormones and vitamins is optional.

This study found that topical Rosmarinus officinalis leaf extract improved hair regrowth in mice and inhibited androgen-associated mechanisms involved in hair loss.

This review discusses recent advancements in the management and diagnosis of primary cicatricial alopecias but reports no new clinical results; emerging insights suggest sebaceous gland dysfunction may play a role in their etiopathogenesis.

This review discusses the use of trichoscopy in diagnosing and managing pediatric hair and scalp disorders and reports no new experimental findings.

This article reviews the use of trichoscopy for diagnosing common hair and scalp diseases and introduces a new classification for specific skin surface abnormalities, without presenting new clinical results.

This study found that among women with frontal fibrosing alopecia, 100% showed dermoscopic elements suggestive of the condition, with perifollicular erythema often indicating disease activity.

This study introduces MicrobeFDT, a tool that clusters chemically similar compounds and links them to gut microbial enzymes and toxicities, demonstrating its utility by uncovering previously unknown metabolism of the cancer drug altretamine.

This review summarizes current and emerging treatments for common hair loss conditions, highlighting good evidence for androgenetic alopecia but noting the lack of long-term data for alopecia areata and cicatricial alopecias.

This study found that Puerariae Flos extract inhibited testosterone 5α-reductase and promoted hair growth in mouse models, suggesting its potential use for treating androgenic alopecia.

In this study, certain trichoscopic features were found to be sensitive and specific for diagnosing primary cicatricial alopecias and its subtypes using dermatoscopy.

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 hair follicles in hair loss patients had increased levels of Propionibacterium acnes, potentially linked to elevated immune response gene expression in miniaturized hair follicles.

This study aimed to identify trichoscopic features that help differentiate between tinea capitis and alopecia areata in children, enhancing diagnosis and treatment decisions visually and non-invasively.

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.

This study found that arctiin, a compound from Arctium lappa, demonstrated protective effects against oxidative stress-induced dysfunction in human hair dermal papilla cells, suggesting potential therapeutic use for alopecia.
