This review discusses the function and pathology of hair follicles and highlights the potential of using dogs as a model to study human hair and stem cell disorders, but presents no new experimental results.

In this study, Tmem30b was identified as a key regulator of outer hair cell structure in mice, and its modulation may offer a therapeutic approach for certain types of hearing loss.

This study found that individuals with heterozygous truncation-type variants in the *DSP* gene exhibit lower skin temperature and higher transepidermal water loss, with specific microscopic skin changes and pseudomonilethrix.

This study reported a new method enabling the observation of the full leg regeneration process in the crustacean *Parhyale hawaiensis* over 10 days, capturing cellular resolution while minimizing photodamage, through innovative imaging techniques and computer-assisted cell tracking.

This article reviews the case of a patient diagnosed with basal cell nevus syndrome and reports no new research findings.

This study identified a novel keratin-associated protein, KAP24.1, which is specifically expressed in the human scalp and located in the hair cuticle.

This study found that enzymatic conversion of Arg-51 in S100A3 protein to citrulline promotes homotetramer assembly, potentially increasing Ca²⁺ binding required for hair cuticular barrier formation.

This study cataloged human type II hair keratins, detailing their expression and differentiation roles in hair follicles and comparing them with type I keratins to explore keratin-pairing principles.

In this study, disrupting the epidermal growth factor receptor in mice led to abnormal hair and skin development, characterized by disorganized hair follicles and systemic disease, providing a model for understanding EGFR's role in skin biology.

This study found distinct localization patterns of S100 family proteins in hair follicles, suggesting their differential roles in normal hair follicle physiology.

mHa2 and mHa3 keratins have different structures and roles in mouse hair and tongue tissues.

This study observed that black-haired areas in female Saluki puppies developed hypotrichosis, with dilated hair follicles containing melanin clumps, while white-haired areas remained normal.

This study demonstrated that a 3D bioprinting technique using a gelatin/alginate hydrogel scaffold can regenerate entire hair follicles in mice, offering potential advancements in hair loss treatment.

This study found that the fungus Microsporum gypseum enzymatically degrades keratin in human hair, with the sequence of degradation reflecting the keratinization and cystine content of individual hair components in vitro.

This review discusses the roles of various PLA2 enzymes in skin health and disease, highlighting potential pathways for future diagnosis and therapy, but it reports no new clinical results.

This review discusses the role of TGM3 in skin and hair follicle biology, human tumor pathology, and genetic abnormalities, and reports no novel results; the authors highlight its potential as a cancer diagnostic biomarker.

Hair and follicle keratins differ in structure and expression, especially in cysteine content.

This study found that lncRNA H19 may regulate CTGF expression in KGN cells by acting as a "sponge" for miR-19b, potentially influencing polycystic ovary syndrome development.

This study explored the complex developmental processes of human hair, emphasizing the intricate interactions required for hair follicle morphogenesis and its implications for drug incorporation and concentration interpretation, particularly in early childhood.

This study presents an improved protocol for isolating and culturing whole neonatal cochlear explants, enabling detailed analysis of hair cells and spiral ganglion neuron cells while simplifying culture steps without sacrificing explant quality, and was successfully tested on mice and rat cochleas.

In this study, researchers found that a scallop adhesive protein (Sbp9 Δ) forms strong adhesive coatings via disulfide-sticker strategies, which also promote hair regeneration in mouse models by activating Wnt signaling and enhancing angiogenesis, proving more effective than minoxidil for androgenetic alopecia.

This study describes the presence of holes in hair fibers, absent in hair follicles, likely forming from daily care actions and removal of extractable substances.

In this study, researchers found that hair follicle orientation in Fz6 −/− mice is disrupted and that hair may reorient itself over time through a self-organized process.

This study found that using a hair dryer at 15 cm with continuous motion causes less surface damage to hair compared to natural drying, although higher temperatures increased overall surface damage.

This study found that recombinant human FGF9 expressed in Arabidopsis thaliana oil bodies significantly promoted the proliferation of NIH/3T3 cells.

This paper critically reviews recent advances in the use of keratin-based biomaterials, highlighting their potential applications in wound healing, drug delivery, and tissue regeneration due to their biocompatibility, biodegradability, and ability to support cell growth.

This review discusses factors affecting hair health, types of alopecia, and the potential of phytochemicals in managing hair loss but reports no new clinical results; it highlights the need for further studies.

This study found that goat placenta extract, when combined with PEGylated liposomes and microspicule gel, significantly promoted hair regrowth in patients experiencing hair loss due to chemotherapy by enhancing hair cell proliferation without causing skin irritation over a 12-week application period.

This study found that scalp cooling resulted in visible hair retention in 53% of breast cancer patients undergoing Epirubicin/Cyclophosphamide and Paclitaxel treatment, with factors like hair bulb diameter, shaft diameter, and anagen rate significantly predicting outcomes.
