This study found that as Japanese women age, their hair cuticle becomes more prone to damage, shifting from type L to type E damage patterns, and hair surface properties, including fatty acid content, deteriorate.

This study found that overexpression of Wnt1a in bone marrow mesenchymal stem cells enhanced mouse hair follicle regeneration and promoted hair cycling.

This review examines hair cosmetics, including shampoos and conditioners, for their formulations and effects, but reports no new clinical findings; it emphasizes the importance of dermatologist knowledge in treating diverse hair conditions.

This review discusses the critical parameters for MALDI IMS sample preparation in skin analysis and highlights its applications in wound healing, neoplasia, and infection research, but reports no new clinical results.

This study successfully developed a method to measure four flavonoids from Platycladus orientalis leaves in rat plasma, which was used in a pharmacokinetic study on healthy rats.

This study reports that novel core-ABS nanocarriers efficiently loaded with dexamethasone and finasteride show potential for dermal drug delivery, exhibiting non-toxic interactions with human keratinocyte cells and skin penetration.

This study found that biodegradable hyperbranched polyesters improved the solubility and loading capacity of hydrophobic drugs, with complete pyrene release achieved in 16 days under enzymatic conditions.

This study proposed the existence of a membrane-like structure between the cuticle and cortex in human hair, which may provide strong protection against external stimuli.

This review discusses the development and types of hair and nails as skin appendages and reports no new research findings.

This article reviews the relationship between the skin and the immune system and discusses how skin manifestations can indicate immunodeficiencies but reports no new research findings.

This study suggests that passage number significantly affects in silico scratch assay results, highlighting the importance of reporting passage number for reproducibility in cell culture experiments.

This review discusses the principles, materials, and applications of melt electrowriting-based 4D printing for creating biomimetic scaffolds, but reports no new clinical results; it highlights recent advancements and remaining challenges in the field.

This study introduced a rapid rehydration approach for creating customizable, multifunctional hydrogel sensors, enabling precise detection of surface deformations and easy integration of layers, highlighting its potential for standardized and adaptable manufacturing of wearable devices.

This review discusses recent advances in hair follicle biology, regeneration, and tissue engineering, highlighting emerging therapeutic opportunities, and reports no new experimental results.

The study found that bioengineered hair follicles work when using cells from the same species but have issues when combining human and mouse cells.

Chicken feather gene mutation helps understand human hair disorders.

This study found that in a mouse model of Leigh syndrome, rapamycin alters brain proteome and may extend survival by targeting protein kinase C.

In this report, researchers observed that a single treatment using a combination of hyperdiluted calcium hydroxylapatite, platelet-rich plasma, and hyaluronidase improved neck wrinkles and skin laxity in two patients, indicating preliminary evidence for the safety and efficacy of this novel therapy.

This study found a 21-fold increased risk of metabolic syndrome associated with a higher waist-hip ratio in women with polycystic ovary syndrome, highlighting the need for focused management in obese patients.

This review highlights that exosomes from adipose-derived stem cells, particularly those enriched with circ-Ash1l, can inhibit ferroptosis and reduce UVB-induced skin aging by delivering GPX4-promoting signals to damaged cells, thus offering a potential regenerative therapy for photoaged skin.

This review discusses the potential impact of lifestyle factors on the progression of androgenetic alopecia and reports no new clinical findings; the authors emphasize the need for more comprehensive studies.

This review highlights the promise of non-viral gene delivery systems, particularly genosomes, over traditional viral vectors due to enhanced safety and efficiency in therapeutic nucleic acid delivery for genetic diseases like cystic fibrosis and malignancies.

This study suggests that typical skin lesions in Carney complex may originate from the pro-melanogenic activity of a specific dermal fibroblast population influenced by PKA signaling.

This review traces the historical understanding and treatment of acne across ancient Egyptian, Greek, and Roman civilizations, but provides no new clinical findings.

This study identified genetic, biological, and technical factors that influence circRNA expression in the human brain, connecting these factors to potential genetic risk for diseases like schizophrenia and type II diabetes.

In this study, grape seed oil was found to be the most effective herbal oil for improving gloss and reducing fractures in various hair types.

This study reported that fermented grapeseed oil may enhance hair permeability and improve strength and color retention in chemically treated hair compared to regular grapeseed or silicone oils.

This study found that hair membrane fluidity is low in the cuticle but high in the cortex and medulla, with treatments like ionic surfactants and oleic acid increasing fluidity in hydrated hair; however, dehydration significantly reduces fluidity throughout the hair.

This study found that a bio-based repair solution containing hydrolysed wool keratin, serine, and transglutaminase improved the physical and chemical properties of damaged hair, increasing its strength, flexibility, and thermal stability while offering long-lasting protection against chemical damage.

This review discusses psychological impacts associated with facial acne, noting that high levels of anxiety and depression among these patients are not linked to oxidative stress, and reports no new clinical results.
