This study identifies key attributes—luminosity, structural integrity, and vitality—that define hair vibrancy, providing insights to guide the development of hair products that align with consumer expectations.

This study demonstrates that a newly developed bio-based, dual-phasic hair serum offers a sustainable and effective alternative to traditional silicone-based serums, enhancing hair cuticle integrity and consumer appeal while supporting environmentally friendly formulation design.

In this study, researchers addressed the limitations of adenosine's practical application in treating inflammation, oxidative stress, and tissue repair due to its poor water solubility and low transdermal permeability. Results are not reported in the abstract.

This review explores the role of nutrition and probiotics in enhancing skin, hair, and nail health through gut microbiota, highlighting the potential of nutritional interventions for cosmetic benefits via the gut-skin axis.

This review highlights the growing use of herbal cosmetics in the personal care industry, emphasizing their skin and hair health benefits. It also underscores the need for quality control and safety assessments to ensure product effectiveness and stability.

Hair follicle stem cells help maintain skin health after injury.

This literature review reports that multivitamin supplementation can enhance hair density and quality in people with suboptimal nutritional status but warns that excessive intake of certain vitamins and minerals may cause hair loss.

This study observed distinct variations in hair medulla patterns among people with different Ayurvedic Prakruti types, linking stronger hair integrity to Kapha-dominant types and weaker, fragmented medullae to Vata and Pitta-dominant types, potentially aiding in Dosha-specific hair care and assessment.

This study introduced an innovative antioxidant serum for skin care, using a lipid active from Rana catesbeiana Shaw, and validated its rejuvenating potential through physical-chemical and microbiological tests that ensured its antioxidant effectiveness, microbiological safety, and formulation stability.

This study found that using 369LAB Lipid Bond, derived from plant oil triglycerides, can restore lipid content in damaged hair to natural levels and improve hair strength, integrity, and resilience after a single application, with benefits persisting even after discontinuation.

This study provides a comprehensive overview of human umbilical cord mesenchymal stem cell-derived extracellular vesicles (HUCMSC-EVs), suggesting their potential to combat aging and alleviate age-related disorders by rejuvenating multiple organs in animal models and discussing engineering strategies to harness their full anti-aging potential.

This review suggests that linoleic acid, an essential fatty acid, may have various beneficial effects on skin health and hair growth through diverse biological activities observed in animal or skin cell models.

Genetic factors affecting skin health and body weight may increase the risk of dermatophytosis.

In this study, varying pH levels from 3 to 12 were found to impact hair structure and proteins, with optimal hair health observed between pH 5 and pH 7, while extreme acidic or alkaline conditions notably affected hair morphology and proteome.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

This study evaluated the protective effects of a hair conditioner containing rice derivatives on natural Caucasian hair using various analysis methods and found that the conditioner, especially with rice germ oil GX-N, effectively improved hair properties even under stress conditions like irradiation.

The hair care routine effectively improved scalp health and reduced fungus in children with kinky hair.

In this study, the researchers found that a combination of honeys from four islands significantly repaired hair integrity, porosity, and surface roughness caused by UV-A and urban pollution, resulting in strengthened, soft, and shiny hair in Asian hair shafts.

This study found that mechanical disruption of the desmosomal cadherin Dsg3 in hair follicle stem cells activates them from quiescence, highlighting its role as a key regulator of stem cell quiescence and epithelial niche integrity.

This study found that gene therapy using a mouse cytomegalovirus vector with telomerase reverse transcriptase or follistatin significantly extended lifespan and improved health markers in mice, without adverse effects.

Hair styling products can damage hair over time.

This study tested the effects of protective pre-treatments on African hair and found that these treatments, combined with moderate grooming, may help maintain cuticle integrity.

This study found that PRC1 plays crucial roles in skin epithelial stem cell regulation, with catalytic and non-catalytic functions impacting epidermal integrity, hair development, and Merkel cell dynamics in murine models.

This review discusses the role of fibroblast growth factors and their receptors in maintaining and repairing epithelial tissues, highlighting their importance in epithelial homeostasis and response to injuries without reporting new clinical results.

This study quantified the effects of chemical treatments like oxidative bleaching and hair relaxing on the movement characteristics of hair strands using a novel high-speed recording method.

In this study, researchers found that follicular and epidermal transglutaminases are biochemically and immunologically distinct, suggesting the possibility of selectively modifying hair or epidermal proteins.

This study suggests that impaired VDR signaling in mice leads to dysregulated Ddit4 expression, impacting hair cycle progression and wound healing.

This study found that the PP2A-B55α regulatory subunit is crucial for ectodermal development in mice, with knockout embryos displaying severe neural and epidermal defects and failing to survive to birth.
