This review assesses the benefits and limitations of various supramolecular hydrogels, including polymeric and peptide-based types, for wound healing, but reports no new clinical results.

This review discusses the senescence–stemness connection in cellular biology and reports no new findings, highlighting implications for both tissue repair and aggressive cancer behavior.

This review discusses the role of the hedgehog signaling pathway in hematological cancers and its potential as a therapeutic target; it reports no new clinical findings.

This study found that nonionic liposomes were the most effective vehicle for delivering reporter genes into the skin of rat pups, compared to other liposome and nonliposome formulations.

This review discusses the complex relationship between stress and various skin conditions, highlighting the role of the skin in the stress response and the brain-skin communication pathways, but reports no new research findings.

This article reviews the development and formulation of shampoos, emphasizing their dual role as cosmetic and medicinal products, but presents no new experimental findings.

This review explores the mechanisms of hair cell death due to factors like noise, ototoxic drugs, and aging and reports no conclusive clinical results; ongoing research may eventually enable preventive treatments for hearing loss.

This review discusses current techniques for scalp reconstruction following oncologic surgery and reports no new clinical outcomes, emphasizing the importance of tailored approaches for satisfactory closure.

This review examines the roles of macrophages and Langerhans cells in skin homeostasis and suggests that understanding these functions can aid in developing therapies for skin and hair regeneration, but it reports no new research findings.

In this study, topical application of fibroblast growth factors was found to promote hair growth by inducing and prolonging the anagen phase in telogenic C57BL/6 mice, suggesting potential as hair growth-promoting agents.

This article discusses the bi-compartmental organization of hair follicle stem cell niches for balancing stem cell cycling and organ growth and proposes similar structures may exist in other adult stem cell niches but reports no new experimental results.

This study reports that erythematous, infiltrated plaques can develop in patients receiving subcutaneous heparin therapy, indicating a possible delayed hypersensitivity reaction to heparin or its constituents.

This study found that patients with alopecia areata had higher levels of Th17 cells and lower levels of regulatory T cells compared to healthy controls, suggesting an immune imbalance in these patients.

This review discusses the potential markers for identifying and studying stem cells in the epidermis and hair follicles, highlighting their role in understanding skin disease pathogenesis and expanding therapeutic options, but reports no new findings.

Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.

This review examines the design strategies for creating conductive hydrogels with adjustable properties for various biomedical applications, highlighting their potential for supporting cell growth, wound healing, drug delivery, tissue regeneration, and biosensing.

This article reviews major types of genetic hair shaft defects and associated syndromes, emphasizing understanding histologic features and diagnostic methods, but reports no new clinical findings.

This study suggests the existence of a new subtype of alopecia, called 'acute diffuse and total alopecia of the female scalp (ADTAFS)', characterized by acute, diffuse hair loss primarily in women and a rapid recovery.

Genetics and hormones cause hair loss; finasteride treats it safely.

This study suggests that sexual dimorphism in adipose tissue functions may be linked to androgen levels, as women with PCOS demonstrated a more masculine adipokine expression pattern.
