This source reviews Japan's extensive 2014 reforms and investments in regenerative medicine, exploring the government's initiatives to accelerate stem cell research while maintaining safety and efficacy.

This study found that emodin from Polygonum multiflorum showed 5alpha-reductase inhibitory activity, which was more potent than alizarin but less potent than riboflavin.

This study identified several significant genetic variants associated with alopecia universalis, including a novel association with HLA-DRB5, which may play a hidden role in the disease.

This article reviews the complex challenges of managing scalp and cranial deformities post-trauma or surgery, advocating for better multidisciplinary approaches to enhance outcomes, but reports no new results.

This study found that Polygonum multiflorum extract may promote hair growth by increasing anagen duration and activating dermal papilla cells in human hair follicles, as observed in cultured cell models.

In a study on nude mice, topical application of Chrysanthemum zawadskii extracts stimulated hair growth and increased hair follicle numbers, suggesting potential for alopecia therapy.

This article series reviews volumetric restoration techniques for different facial regions by expert authors, offering assessments of specific products but provides no new clinical results.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

This study found that overexpressing the PML protein in transgenic mice decreased skin tumor occurrence and delayed their progression, highlighting PML's potential role in influencing keratinocyte growth and differentiation.

This study suggests that local skin inflammation may enhance the deposition of autoantibodies in the skin, potentially affecting the severity of pemphigus lesions in mice.

This study documented distinct expression patterns of stem cell markers LGR5 and LGR6 in various human skin tumors, highlighting differences in their potential roles and contributions to tumor development.

This study found that proton minibeam radiotherapy demonstrated a potential tissue-sparing effect in epidermis models by spatially confining DNA damage, suggesting reduced side effects in radiotherapy.

This study found that short-term exposure to PM2.5 and Asian dust particles did not increase skin symptoms in schoolchildren.

This review discusses the confusion and misuse of Polygoni Multiflori Radix, Cynanchi Wilfordii Radix, and Cynanchi Auriculati Radix in Korea, highlighting their plant origins, uses, and toxicities, without providing new clinical results.

This study found that a novel hydrogel scaffold, cGEL, significantly increased melanin production and melanotic gene expression in human melanocytes compared to other graft materials, suggesting its potential as a superior carrier for skin grafting.

This study found that among eleven tested polymethoxyflavones, 5-hydroxy-7,4′-dimethoxyflavone was the strongest steroid 5α-reductase inhibitor and suggests potential use for benign prostatic hyperplasia treatment.

This study found that the clionasterol-rich hexane fraction of Caulerpa racemosa may protect against particulate matter-induced skin damage by reducing oxidative stress and mitochondrial-mediated apoptosis in human keratinocytes and zebrafish.

This case report describes frontal fibrosing alopecia in a woman with primary biliary cirrhosis and polymyalgia rheumatica, suggesting a possible autoimmune link to this form of hair loss.

In this study, saponins from Korean red ginseng were found to protect against the harmful effects of airborne particulate matter on human skin cells by reducing oxidative stress, inflammation, leptin expression, and melanin production.

This study found that Swiss cattle exhibiting rat-tail syndrome are heterozygous for genetic variants linked to pigmentation and color dilution, likely due to Holstein introgression in the Simmental breed.

This study developed a new melanocyte cultivation medium without chemical mitogens, melanogenesis enhancers, or bovine products, demonstrating successful proliferation and melanotic differentiation of human melanocytes from hair follicles.

This study found that Polygoni Multiflori Radix (PMR) reduced collagenase and elastase activity after UVB damage in fibroblasts, suggesting potential anti-aging properties for cosmetic use.

PMS nanoparticles improve damaged hair by protecting and restoring its surface and color.

This study reports that retinol acetate inhibited the pro-oxidant effects of benoxaprofen on polymorphonuclear leucocytes in vitro.

This case report describes an 8 cm giant pilomatricoma on a 67-year-old man's scalp, revealing distinct transcriptional patterns related to hair follicle factors and keratin through spatial gene expression analysis.

In this study, researchers found that exosomes derived from Pinctada martensii mucus can effectively inhibit melanin production in melanoma cells and zebrafish without adverse effects, potentially offering a promising therapeutic strategy for treating pigmentary disorders by modulating the NF-κB signaling pathway.

This study found that AI using YOLOv11 architecture can reliably differentiate between hyaluronic acid and silicone oil cosmetic fillers on ultrasound, achieving high accuracy, whereas identifying calcium hydroxyapatite and polymethylmethacrylate remains less consistent, requiring further improvements.

This study found that Polygoni multiflori Radix water extracts accelerated hair regrowth and hair follicle development in mice, showing a safer profile compared to minoxidil.

This study found that long-term exposure to particulate matter (PM2.5 and PM10) is associated with an increased risk of developing alopecia areata, with possible involvement of inflammatory pathways, suggesting PM as a modifiable environmental risk factor.

This review discusses how permanent micropigmentation can restore eyebrow appearance and potentially improve psychosocial well-being in cancer survivors experiencing alopecia after chemotherapy, but it reports no new clinical results.
