Hair can regrow if the sebaceous gland is intact, even if the hair root is removed.

This study observed that using a relaxed suture technique on scalp incisions may prevent linear scars by reducing pressure on upper stem cells.

This article discusses the minimal research on hair growth physiology and highlights Dr. Masumi Inaba's contributions to understanding androgenetic alopecia, but reports no new experimental results.

This study found that using an antimicrobial lotion for 18 months may reduce inflammation and potentially partially reverse hair loss in men with androgenetic alopecia.

This study identified Lgr5 and Lgr6 as receptors expressed by small populations of stem cells in various adult organs, with Lgr5+ve cells forming long-lived organoids in certain mouse models.

Junctional proteins stabilize the inner root sheath and connect the companion layer in human hair.

Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.

This study observed that frontal fibrosing alopecia also occurs in men, with clinical features and areas of involvement similar to those seen in women, but often affecting sideburns and facial hair.

This correspondence discusses the diagnostic criteria for frontal fibrosing alopecia but reports no new research findings, agreeing with many previously suggested criteria.

This review summarizes the current treatment modalities for frontal fibrosing alopecia and provides a practical guide for clinicians, but reports no new clinical results.

This study found that in anagen hair follicles, the basement membrane zone components showed decreased expression in the lower hair bulb, with a complete absence of BP230 at the dermal papilla junction, suggesting an incomplete hemidesmosome structure in these regions.

This study describes how arrector pili muscles form a single muscular structure shared by all hair follicles within a follicular unit at the isthmus level in scalp skin.

This review discusses the role of intermediate filaments in cell signaling and differentiation, emphasizing their impact on stem cell function, development, and disease, but reports no new clinical results.

In this study, researchers found that the expression of vimentin, desmin, and laminin in rat skin contributes to cell structure and tissue integrity, with varying reactions across different cell types.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

This study found that methylene blue staining may reveal anatomical details of intraepidermal nerve fibre endings in the rat mystacial pad with greater clarity than the zinc iodide-osmium tetroxide technique.

This study observed that methylene blue staining and zinc iodide-osmium tetroxide techniques effectively revealed anatomical details of intraepidermal nerve fibre endings in the rat's mystacial pad, suggesting their potential role in mechanoreception.

This study suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.

This study observed that the mechanical connection between hair follicles and connective tissue in human fetal scalp skin is weaker than in the corresponding skin components, reflecting dynamic processes in hair growth.

This study found that lymph vessel morphology and density in airways differed based on location and type of epithelium, with the highest density in the ciliated epithelium of the nasal passages and site-specific patterns apparent in both fetal and adult specimens.

This study revisits and reproduces Felix Pinkus' concept of the vitreous membrane in hair follicles, suggesting these structures may play a role in differentiation or nutrition due to their location in metabolically dynamic regions.

This review discusses the roles and interactions of intestinal intraepithelial lymphocytes in maintaining mucosal barrier integrity and highlights how their dysregulated responses may contribute to intestinal pathologies.

This study found that desmosomal adhesion plays a crucial role in epithelial morphogenesis and cell positioning, equivalent in importance to that of adherens junctions.

In this study, researchers used quantitative fate mapping to investigate how the infundibulum, part of the epidermis, is maintained during adulthood, finding that progenitors maintain this tissue through stochastic cell fate choices, with cells at the bottom providing transient support during hair growth phases.

This review discusses the cell biological characteristics of the outer root sheath of normal human hair follicles and highlights some similarities and differences with trichilemmal tumors, but reports no new results.

This study suggests that the inner root sheath plays a significant role in maintaining hair follicle homeostasis during the catagen phase's early stages.

This study found that seborrheic keratosis lesions contain high levels of hair sheath keratin, suggesting they may originate from the upper hair follicle.
