This article reviews common pitfalls in biopsy site selection and technique that can lead to misdiagnosis of various skin conditions, highlighting the importance of proper biopsy practices for improving diagnostic accuracy.

This review discusses neural mechanisms involved in hair growth control, focusing on piloneural interactions, but reports no clinical findings; the authors suggest further exploration for managing hair growth disorders.

This review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.

This study found that mTOR signaling plays a crucial role in activating hair follicle stem cells by balancing BMP-mediated repression, essential for hair regeneration.

This review discusses the biology of hair follicle stem cells and highlights their potential for applications in regenerative medicine, drug, and gene delivery, but reports no new clinical results.

Certain fungi and bacteria help orchid seeds germinate and plants grow better.

This review discusses the roles of immune responses and cells in skin health and disease, emphasizing recent insights into their mechanisms and potential therapeutic applications, but presents no new experimental results.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

This study reports that a newly developed polyherbal phospholipid complex cream containing Citrus auranticum and Glycyrrhiza glabra extracts improved polyphenol retention in the skin, suggesting potential as an anti-aging cosmeceutical.

In a 24-week randomized trial, this study found that the RAMACAP laser helmet significantly increased hair density and diameter in androgenetic alopecia patients compared to a sham device, although limitations included a small sample size and potential issues with the control used.

This study identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

This article reviews the role of vasoactive intestinal peptide in maintaining immune privilege in hair follicles and does not report new findings; the authors propose it as essential for immune homeostasis in alopecia areata.

This study found that sweat gland stem cells primarily maintain sweat gland homeostasis but can trans-differentiate to aid in epidermal healing and regenerate diverse skin structures under certain conditions.

This study found that serum calcium, serum ferritin, and vitamin D3 levels were lower in students with premature graying of hair compared to controls, suggesting a potential role in the condition.

This review discusses the emerging roles of transit-amplifying cells in tissue regeneration and cancer formation, highlighting their significance beyond a mere transitional state in hair follicles and the hematopoietic system.

This article reviews the role of polarity proteins in epidermal morphogenesis and homeostasis and discusses how their alteration may contribute to skin disease, but reports no new experimental findings.

In this study, Meis1 was found to regulate epidermal homeostasis and act as a proto-oncogenic factor in skin tissues, with differences in expression patterns between normal and tumor cells.

This article reviews potential causes and treatments for sensitive skin and reports no new clinical results; the authors emphasize neurogenic inflammation and cosmetic choices as key factors in managing the condition.

This study found that Merkel cell clusters require Frizzled6 signaling for their polarity information, while other hair follicle-associated structures align their orientation based on the hair follicle itself.

New skin substitutes for treating severe burns and chronic wounds are being developed, but a permanent solution for deep wounds is not yet available commercially.

This review discusses trichotillomania's clinical features, prevalence, and treatment options, highlighting the potential benefits of behavior therapy and pharmacotherapy but reports no new clinical findings.

This study found that in mice lacking EGFR, elevated Wnt signaling disrupts hair follicle development by affecting cell proliferation and differentiation, revealing a critical role for EGFR in regulating these processes.

This review discusses the generation of germ cell-like cells from skin-derived stem cells and reports no new results; the potential for these cells to produce viable progeny remains unclear.

This review discusses the role of hair dyes in cosmetic dermatology, their effects on hair and scalp health, and the importance of dermatologists understanding potential side effects; it reports no new findings.

This study found that inhibiting EGFR signaling in mice can prevent alopecia caused by cyclophosphamide treatment, highlighting its potential role in managing chemotherapy-induced hair loss.

This paper reviews different types of hair shaft dysplasias and does not report any new clinical findings.

This review discusses the management of androgenic disorders in women, highlighting that treatment is generally more effective than recognized, though improvement may take weeks or months to appear.

This review discusses the multifaceted roles of hair follicles in skin health, including potential contributions to skin neoplasias, and reports no new results.

This review examines the role of stem cells and their niches in continuously growing ectodermal organs like teeth, hair, and claws, providing insights from mouse models without presenting new research findings.

This study found that stressed dermal fibroblasts significantly increased dopa oxidase activity in melanocytes from hair, skin, and eyes, suggesting the involvement of fibroblast-derived factors like basic Fibroblast Growth Factor.
