In this study, researchers developed a standardized Ayurvedic hair pack using natural ingredients like Shikakai and Amla and confirmed its safety and pH suitability; they concluded it could be a scientifically validated alternative to synthetic hair products.

The researchers monitored various pollutants in real cosmetics industry wastewater and reported high removal efficiencies for parameters like Chemical Oxygen Demand and heavy metals through coagulation-flocculation, yet suggested that more effective COD treatment alternatives are necessary to better protect the environment and human health.

In this study, a flexible adhesive self-powered wound dressing promoted skin regeneration and reduced inflammation in vivo using sound wave driving, without requiring skin bending or external devices.

This study found that people with chronic telogen effluvium had lower hair and serum iron levels and higher serum copper levels compared to healthy controls.

This research highlights that various environmental pollutants, including particulate matter, tobacco smoke, and heavy metals, can significantly affect hair follicle health, linking them to conditions like alopecia areata and androgenetic alopecia, underscoring the need for further study in this area.

This review compiles existing research on infrared radiation's effects on human skin, noting both its potential harmful thermal impacts and encouraging therapeutic applications, but reports no new clinical results.

This study found that IL-9 influences the behavior of human primary keratinocytes by promoting motility while reducing invasion potential through a novel mechanism independent of matrix-metalloproteinases.

This study analyzed hair samples from marathon runners with hair loss, finding distinct patterns in mineral content and heavy metal contamination, with more male than female runners experiencing hair loss.

This study found that the levels of heavy metal contamination in hair were higher in both men and women with hair loss compared to those without.

This study found that plasmapheresis treatment in children with total alopecia led to a decrease in lead levels and improved hair growth, which was not achieved with Spirulina platentis supplements.

This study found that FAM19A5 acts as a negative regulator of wound healing by hindering keratinocyte migration and partially transitioning them between epithelial and mesenchymal states, suggesting that targeting the FAM19A5-PPARD-Snail axis could offer new therapeutic options for impaired wound repair.

In this study, researchers created a hydrogel that reduces oxidative stress and releases a pro-angiogenic drug in response to enzyme activity, which accelerated healing and improved tissue regeneration in chronic diabetic wounds during in vivo experiments.

This review found that solar radiation, pollution, and trace metals cause significant damage to human hair, with factors like UVB radiation primarily affecting light-colored and bleached hair; most data were derived from in vitro and ex vivo simulations.

In this review, the authors reported that sprout extracts, rich in bioactive compounds, show promising effects on skin health, such as enhancing collagen synthesis, improving hydration, and reducing inflammation, though most evidence comes from laboratory and animal studies.

This study found that Punica granatum ethanolic leaf extract may alleviate skin fibrosis in rats by modulating inflammation-related pathways and reducing dermal alterations.

This study found that mesenchymal stem cells mainly promote skin regeneration and delay aging through paracrine activity, releasing growth factors and cytokines that protect against oxidative stress and stimulate healing.

This research observed that Salvianolic acid B (Sal B) significantly promoted hair regeneration in vivo and in vitro, outperforming minoxidil in a mouse model of androgenetic alopecia, by activating Wnt/β-catenin and mTORC2/Akt pathways and upregulating MMPs and MAPKs.

In this study, orally administered Centella asiatica extract, standardized for asiaticoside content, significantly improved skin barrier function, elasticity, and reduced signs of UVB-induced photoaging in hairless mice, highlighting its potential as a nutricosmetic for skin health.

Light skin shows more inflammation from sun exposure than dark skin.

This review discusses how urban air pollutants may influence the regulation of JAK3 signaling in alopecia areata and reports no new experimental results; the authors integrate existing data to map potential pathways and biomarkers.

This research review observed that topical hormone replacement therapy, particularly estradiol and estradiol-testosterone combinations, significantly increased Type I and III collagen synthesis in the skin of postmenopausal women, suggesting benefits against collagen loss-related skin aging effects such as reduced elasticity and increased dryness.

This study observed that individuals with type 1 diabetes mellitus have notably lower levels of essential and trace elements like Calcium, Potassium, and Zinc in biological samples compared to non-diabetic controls.

In a laboratory study, Grateloupia elata extract demonstrated antioxidant and anti-aging effects by scavenging free radicals, inhibiting collagenase and elastase, increasing procollagen production, and reducing MMP-1 secretion, suggesting its potential use in functional cosmetics.

Monocyte-derived dendritic cells play a key role in UVB-induced skin sensitivity and inflammation.

This article discussed the potential risks of commercial hair oils, which may contain harmful ingredients, and suggested that additive-free ayurvedic oils could offer a safer alternative for maintaining healthy hair, while urging dermatologists to be informed about different herbal hair oil options.

This study reported that Moracin M, a compound from the Moraceae family, significantly promoted hair growth and vascular regeneration by enhancing cell proliferation and Wnt signaling activation in laboratory settings, suggesting it may offer a promising alternative to existing hair growth treatments like minoxidil.

This study revealed that basement membrane dynamics are crucial to hair follicle development, influencing progenitor cell behavior and cell division patterns in developing mouse hair follicles.

This study found that topically applied melatonin exerts significant anti-aging effects on human scalp skin ex vivo, including increased SIRT1 expression and reduced mTORC1 pathway activity.

This study observed that a novel extracellular matrix hydrogel made from human fibroblast-derived matrix improved wound healing in animal models, showing significant effects such as hair follicle formation, reduced inflammation, enhanced pro-healing growth factor levels, and interaction with macrophages, compared to traditional collagen hydrogels.

In this study, Hibiscus rosa-sinesis flower extract was found to contain 0.33% quercetin according to HPTLC analysis and 0.37% according to HPLC. Heavy metals measured were within acceptable limits, supporting the standardization of the plant material for efficacy and safety testing.
