This study conducted a comprehensive pharmacognostic and phytochemical analysis of Sphagneticola calendulacea stem, identifying tannin-filled cells, various secondary metabolites, and significant physicochemical characteristics, which could aid in authenticating the plant for therapeutic use.

This study observed that using an environmentally friendly bovine milk permeate effectively and cleanly removes wool from sheepskins without harming the skin, and results in smoother leather compared to traditional chemical methods.

This review article highlights recent advances in microneedle technology for wound healing and tissue regeneration, discussing various cargo types, structural designs, and fabrication methods, and suggesting guidelines for designing microneedle systems tailored to specific applications.

This study found that peroxide-rich plasma-activated water caused minimal morphological damage to hair, while nitrate-rich plasma-activated water induced significant damage, especially in porous hair types.

This study used a new multimolecular spectral method to uncover structural differences in hair keratin from individuals with androgenetic alopecia compared to healthy individuals, identifying potential biomarkers and providing insights for developing new treatments.

This review discusses current strategies and materials in tissue engineering for skin regeneration, emphasizing design approaches and suggesting directions for future research; it reports no new clinical findings.

This study presents a method for directly measuring the solubility of solid chemicals in the skin's stratum corneum under various humidity conditions, emphasizing its importance for dermal drug delivery and chemical safety assessments.

This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.

In this study using a virtual screening approach, eriocitrin and silymarin were identified as potent flavonoid compounds that strongly and stably interacted with 5α-reductase type II, suggesting potential development as novel treatments for androgenic alopecia.

This study examined the evolutionary and functional homology of steroid 5α-reductase and DET2 proteins, identifying protists as a common ancestor, and discovered a new subclass DET2-like in plants, potentially involved in polyprenol reduction.

This study found that thioglycolic acid molecules in hair treatments are primarily located in intrafibrillar unordered areas, where they redistribute disulfide bonds.

This paper reviews the literature on acquired trichorrhexis nodosa, a clinical hair loss diagnosis associated with hair care practices, particularly in those with tightly curled hair, and emphasizes management through protective hair care regimens rather than traditional prescription therapies.

This study of African-American women found that those perceiving greater hair breakage showed lower break stress and higher premature failure rates, linked to grooming practices and hair curvature.

This study introduced the C-CAT, a new assessment tool for central centrifugal cicatricial alopecia, and found that established treatments improved symptoms in most patients over six months.

This study determined that previous reports mistakenly identified different polymorphs of furosemide and finasteride, which are actually identical, due to incomplete data collection in single-crystal X-ray diffraction analysis.

This study found that the molecular structure of hair is more sensitive to synchrotron X-ray radiation than its supramolecular architecture, indicating potential concerns for biological analyses using such radiation.

This review summarizes the roles of matricellular proteins in skin stem cell niches, highlighting their contribution to stem cell fate, self-renewal, and potential implications for wound healing and aging.

This review summarizes recent advances in understanding the molecular mechanisms of hair follicle formation and discusses potential future clinical applications for treating hair loss and skin tumors, but it reports no new clinical results.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This article outlines a protocol for scanning electron microscopy of murine skin and primary keratinocyte monolayers, providing a guide for sample preparation and examination.

In this study, transfection experiments showed that mutations in the K85 gene affect filament formation with K35, which may impact hair formation related to ectodermal dysplasia.

Hyaluronic acid microneedles help deliver minoxidil derivatives effectively for hair regrowth.

This publication provides a standardized nomenclature for classifying microscopic lesions in laboratory rat and mouse skin, aiming to harmonize international toxicological research.

This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.

Lustre mutant sheep have normal hair structure and proteins but differ in felting properties.

This study examined argan oil inclusion complexes with β-CD, finding that these complexes improve the antibacterial efficacy, uniformity, and mechanical performance of hair treatment formulations while enhancing the durability of bleached hair, suggesting their potential as stable and effective cosmetic ingredients.

In this study, a subcutaneous injection of recombinant RSPO1 was found to activate hair follicle stem cells and enhance hair regeneration in mice by stimulating the Wnt/β-catenin signaling pathway, suggesting its potential as a treatment for hair loss.

This study found no significant difference in the tensile properties of hair from different scalp positions, suggesting that microscopic structural heterogeneities may play a role.

This review discusses the structural and functional advances in understanding sulfotransferases and sulfatases, highlighting new insights into enzyme mechanisms and inactivation by clinically relevant aryl sulfamates, but provides no new experimental results.

This review discusses the structure and function of steroid nuclear receptors, particularly focusing on androgen receptor dysregulation in prostate cancer and androgen insensitivity syndromes, without reporting new experimental results.
