This study found that trichoscopy is a useful tool in differentiating between alopecia areta and trichotillomania on the eyebrows based on distinct hair and follicle features.

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

This article provides a multiple-choice quiz based on dermatology information but shares no new research findings.

This paper reviews the differential diagnoses and diagnostic tests to distinguish alopecia areata from other types of hair loss, without providing new clinical findings.

This study identified distinct clinical and dermatoscopic features to differentiate non-scarring patchy alopecia in SLE from alopecia areata, emphasizing the value of serological tests in diagnosis.

This article describes how recognizing distinct trichoscopic features aids in diagnosing various dermatological conditions and hair loss, but it reports no new clinical findings.

This study found that the repressive histone mark H2AK119ub links inhibitory FGF signals with the quiescent state in hair follicle stem cells, revealing a signaling-epigenetic axis crucial for maintaining stem cell quiescence and tissue homeostasis.

This study analyzed dermoscopic findings in alopecia areata among children and adults, discovering that exclamation mark hairs are more common in children, while yellow dots appear more often in adults, indicating the importance of age-specific evaluation in diagnosing this condition.

This paper explores how hair functions as a geographical lens to redefine the body's borders, influencing perceptions of identity and power.

This article explores questions about dormant hematopoietic stem cells and suggests avenues for future research, but does not present new experimental results.

This study examined children with trichotillomania using a set of specific questions to better understand the condition and aid clinicians who may be unfamiliar with it.

In this case report, a 20-year-old woman exhibited progressive asymptomatic hair loss with a pattern inconsistent with alopecia areata or female pattern hair loss, showing areas of both extending and improving hair loss.

This article proposes criteria to differentiate between medicalization and over-medicalization, examining the consequences and ethical considerations of misidentifying medical issues, and suggests guideline questions to help draw clearer boundaries in medicine.

This study reports that during late embryogenesis and early postnatal development, K79-expressing keratinocytes change and die independently of sebaceous glands to form the hair follicle opening, potentially influencing conditions like ingrown hairs or acne.

This review discusses the role of hair microscopy in diagnosing alopecia, stating that while it excludes diagnoses related to hair breakage, it only confirms nonspecific short anagen in alopecia cases.

This case report describes occipital hair transplantation for therapy-resistant alopecia areata in eyebrows, observing 80% hair re-growth two years post-surgery and suggesting surgical options may be useful for stable cases.

This study observed that using 3D dermal papilla microtissues enhances hair follicle regeneration and gene expression compared to 2D cultures, indicating their potential for hair growth drug screening.

This review discusses the distinct roles and surprising developmental flexibility of multiple somatic stem cell types in tissue maintenance and repair, reporting no new results but highlighting emerging questions about their regulation and origins.

This protocol describes using two-photon laser-scanning microscopy to study hair regeneration in live mice, offering detailed imaging capabilities for observing hair follicle stem cell behavior and manipulating cellular populations.

This review explores the mechanisms of adult stem cell self-renewal, using skin as a model, and reports no new results but raises important unanswered questions in the field.

This review outlines diagnostic possibilities for diffuse, nonscarring hair loss in women and reports no new clinical findings.

This case study identified the condition as Monilethrix in a 17-year-old female, characterized by a beaded hair appearance and linked to a genetic cause.

This study found that permanent chemotherapy-induced alopecia was relatively common three years after treatment among breast cancer patients receiving adjuvant chemotherapy, particularly those on taxane-based regimens.

This review discusses genetically-engineered mouse models for studying melanocytes and reports no new experimental findings; it emphasizes their potential to address unanswered questions in melanoma biology.

This article reviews the biology of epithelial stem cells and their role in tissue self-renewal, maintenance, and regeneration, and it highlights the clinical implications of understanding their signaling pathways, but it presents no new clinical findings.

This review discusses the role of signaling networks in sebaceous gland development and disorders, highlighting recent insights from mouse models and cell line studies, but reports no new experimental results.

This review discusses the onset and characteristics of telogen effluvium following SARS-CoV-2 infection, implicating stress, cytokine release, or viral damage, and reports no new clinical results.

This study observed a high degree of plasticity in somatosensory axons innervating Merkel cells in mouse skin, finding that both axons and Merkel cells underwent dynamic remodeling, with their interactions influencing axonal branching and maturation.

In this study, highly dynamic remodeling was observed in mouse somatosensory axons and Merkel cells, indicating that epithelial-neural interactions help maintain homeostatic remodeling, with additional intrinsic neural mechanisms contributing to axonal plasticity.

This review discusses the role of stem cells in cutaneous wound healing and reports no clinical results; the authors highlight the need for better understanding of underlying mechanisms for future therapies.
