This review discusses the use of natural products in cosmetic preparations for skin and hair care, but reports no new research results.

This review presents current evidence on medicinal plants and their phytoconstituents, such as phenolic compounds, used in acne treatment, highlighting their potential as alternatives to conventional therapies due to issues like antibiotic resistance and high cost.

This review discusses the biological properties of 18β‐glycyrrhetinic acid derived from licorice root, highlighting its potential anti-inflammatory, antioxidant, and antimicrobial benefits in treating dermatological disorders, and reports no new experimental results.

This research found that deleting the SLC3A2 gene in hair follicle stem cells disrupts their maintenance and proper differentiation, leading to hair follicle growth defects and altered skin regeneration through a YAP/Taz-dependent pathway.

In this study, tubular 3D bioprinted structures made from sodium alginate and gelatin, containing NIH/3T3 fibroblast cells, demonstrated the ability for cell growth and network formation over 6 weeks, although structural tensile strength decreased with cell growth and polymer degradation.

This article reviews the clinical use of platelet rich plasma for skin regeneration, highlighting the challenges of inconsistent outcomes due to varying preparation protocols, and calls for standardized models to better assess its effectiveness.

This review outlines the role of dermal fibroblasts in wound healing and highlights their potential in developing new cellular therapies, but reports no new clinical results.

The researchers found that plant extracts from Papaver rhoeas L., Clitoria ternatea L., and Carthamus tinctorius L. are effective natural cosmetic dyes, offering intense and stable colors without cytotoxicity.

This study assessed the antioxidant properties and contents of carotenoids and chlorophylls in 10 plant oils, finding fenugreek seed oil to be highest in carotenoids and pomegranate oil most active against free radicals, highlighting their potential as natural materials with antioxidant benefits.

This review highlights the potential of olive mill wastewater as a sustainable source of cosmeceutical ingredients with antioxidant, anti-inflammatory, and dermatological benefits but reports no new clinical findings.

This review discusses the potential of olive mill wastewater as a sustainable source of dermatological ingredients with antioxidant and regenerative properties but reports no new clinical findings.

This review discusses the dermatological potential of olive mill wastewater as a sustainable source of high-value cosmeceutical ingredients but reports no new clinical results.

In this study, researchers reported that hair follicle stem cells maintain quiescence through a PIEZO1-dependent mechanism that senses mechanical forces and translates them into localized calcium influx, involving a transcriptional network that regulates cell adhesion and cytoskeleton-related genes.

This study found that nuclear androgen receptor expression was enhanced by dihydrotestosterone in rat gubernacular mesenchyme, but this did not affect muscle morphology or matrix composition during fetal development.

This article provides guidelines and indices for a three-point cantilever bending test to measure mechanical properties of hair treated with both conventional and naturally-derived styling polymers, reporting no new experimental results.

In this study, researchers developed a multifunctional hydrogel for wound healing, incorporating antibacterial and antioxidant properties that demonstrated significant inflammation reduction and tissue regeneration in animal models, with high antibacterial efficacy against E. coli and S. aureus.

This review investigates how the chirality of peptides affects their ability to form hydrogels, comparing the structural and mechanical properties of hydrogels made from homochiral and heterochiral peptides, and discussing their potential biological applications.

The hydrogel is safe, reduces oxidation, and helps heal wounds effectively.

JAK inhibitors improve hair growth in alopecia areata, especially in patchy types.

This study found that incorporating Canavalia ensiformis lectin into alginate and carboxymethylcellulose films enhanced angiogenic factor expression, suggesting these biopolymer films could be an effective alternative for wound treatment.

This study investigated the effects of wool-derived hydrolysed keratin peptides on relaxed textured hair and found that mid- and high-molecular weight peptides improved mechanical strength and reduced breakage in different humidity conditions.

This review highlights that while scientific validation supports the traditional use of Musa paradisiaca (plantain) primarily for physiological conditions, data on its antiviral and in vivo antimicrobial efficacy is limited, yet its constituent compounds indicate potential for further drug development research.

This review highlights that extracts from *Hamamelis virginiana* (witch hazel) exhibit antimicrobial, anti-inflammatory, antioxidant, and wound-healing properties in various studies, showing promise for future therapeutic use in dermatology and cosmetology, particularly for skin treatments.

This study concluded that extracts from fermented pumpkin peel and pulp, processed with Lactobacillus strains and kombucha, may serve as multifunctional cosmetic ingredients, offering antioxidant protection, anti-aging, and skin regeneration benefits by demonstrating cytoprotective effects and reducing inflammatory cytokines in cell assays.

This study highlights the distinct distribution patterns of extracellular matrix components in the scalp skin of male and female androgenetic alopecia patients, with increased elastin staining intensity observed in male cases.

This study found that human hair exhibits significant deformation in its intermediate filaments under strain, with recovery taking about 1000 minutes, suggesting a self-healing period post-mechanical stress. Additionally, cuticle scales deform much less than the cortex, and the Poisson ratio aligns with soft matter properties.

This study presented 3D images of human dermis, revealing fewer elastic fibers near hair follicles compared to other regions, which may aid future skin engineering efforts.

This study found that combining Aliaxin® Global Performance with Viscoderm® Skinkò E improved hydration and appearance of nasolabial folds more effectively than using Aliaxin® Global Performance alone.

In this study, intradermal injection of GCSF-mobilized peripheral blood stem cells from young pigs rejuvenated skin in aged pigs by increasing collagen, elastin, and cell renewal rates.

The researchers concluded that hairless dogs can serve as an effective model for studying hypertrophic scarring due to their development of scars with morphological similarities to human hypertrophic scars.
