This study suggests that Artemis, particularly phosphorylated at serine 516, may have roles in hair follicle growth by influencing differentiation, proliferation, apoptosis, and cell cycling.

This review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.

This study found that direct immunofluorescence of hair is a simple and non-invasive alternative for monitoring pemphigus vulgaris, matching skin biopsy results in the cases observed.

This genetic study identified a potential interval for the Marie Unna hypotrichosis gene but found no mutations in the nearby hr gene, suggesting its involvement remains unconfirmed.

This study reported the feasibility of detecting six cell-cycle-related nuclear markers in plucked human scalp and eyebrow hair, providing valuable insights for future intervention studies.

This study found that gels containing glycyrrhizic acid and aqueous Glycyrrhiza glabra extract significantly reduced underarm hair growth in terms of area, thickness, length, and number compared to their gel bases.

This study found that water extract of olive leaf may enhance markers linked to epidermal and dermal stem cell activity and potentially improve skin aging, especially in individuals who do not exercise regularly.

This paper examines the potential autoimmune basis of alopecia areata, but reports no new clinical results; the focus is on analyzing complement levels and macrophage migration inhibition factor in patients.

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 article reports that cocaine injections can lead to skin lesions containing talc crystals at the sites of injection.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

This extensive review discusses the clinical manifestations, potential associations, and treatment approaches for lichen planus, but reports no new clinical results, highlighting gaps in evidence for therapeutic strategies.

This study found that trichohyalin, a protein previously thought to be restricted to hair and tongue, is also present in isolated cells within the granular layer and stratum corneum of normal human epidermis.

This study found that the hair interior defect in AKR/J mice is linked to a mutation in the Soat1 gene, which disrupts SOAT1 protein expression and affects lipid metabolism critical for normal hair formation.

This practical guide introduces methods to study human dermal white adipose tissue but does not report new clinical results, emphasizing available techniques and staining protocols.

In this study, human hair follicles showed varying expression of cholesterol transport proteins during the hair cycle, suggesting a potential role of cholesterol in hair growth and cycling.

This study reported that trichoscopy revealed distinctive patterns across different autoimmune bullous diseases, suggesting it can be a useful preliminary diagnostic tool for differentiating these conditions.

This study describes a method for labeling and tracking hair follicle stem cells in mouse skin using a Cre/lox recombination system with tamoxifen, providing insights into stem cell behavior and contribution to tissue regeneration.

This study found that polymeric micelle nanocarriers delivered pharmacologically relevant amounts of spironolactone to the epidermis and upper dermis, with higher delivery to pilosebaceous units, suggesting potential for treating glucocorticoid-induced impaired wound healing and pilosebaceous androgen-related skin diseases.

This study observed that a 3D culture model of hair follicle cells showed an anagen-like phase between days 3 to 6 and transitioned to a catagen-like phase by day 7, highlighting cell differentiation and structural development over time.

Lichen planopilaris is a rare, chronic condition causing hair loss, mainly in middle-aged women, and early treatment is important to prevent permanent baldness.

This study found that patients with systemic lupus erythematosus and diffuse hair loss showed non-scarring alopecia without inflammation and a decrease in total hair follicles.

In this study, SFRP1 expression was found to be upregulated in hair follicles from men with androgenetic alopecia, with the transcription factor FOXC1 playing a significant role in its regulation.

This study found that frontal fibrosing alopecia and lichen planopilaris have similar histopathological features, but FFA exhibits more prominent apoptosis and less inflammation with spared interfollicular epidermis.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

This study found that blue light at a wavelength of 453 nm promoted hair growth ex vivo, potentially through interacting with OPN3 receptors in human hair follicles.

This guide reviews the biology of sebaceous glands and their evaluation methods, emphasizing their roles beyond lipid production in skin health and disease, and reports no new research results.

Scarring alopecias are complex hair loss disorders that require early treatment to prevent permanent hair loss.

This study observed that in pemphigus vulgaris patients, hair loss and alopecic patches may result from anti-desmoglein autoantibody-mediated acantholysis and inflammatory changes, leading to non-scarring alopecia with potential for regrowth after treatment.

This article reviews insights into the pathogenesis of primary cicatricial alopecias, such as lichen planopilaris, provided by emerging technologies, but it does not report new clinical results.
