This article reviews various hair straightening methods, discussing their mechanisms and potential effects on hair, but it reports no new clinical results.

In this study, polydopamine emerged as a safe and effective alternative to traditional hair dyes like PPD for dyeing gray hair permanently, showing resistance to detergents and causing less toxicity and hair loss in mice.

This study found that Wnt signaling, crucial for lung development, may be disrupted in severe asthma, potentially affecting cell proliferation and senescence through complex mechanisms.

This study found that domestic temporary hair dyes may pose a health risk due to their cytotoxic effects on human red blood cells and NIH/3T3 cell lines.

In this study, researchers isolated five new compounds from Monascus purpureus wmd2424 and found that four exhibited mild antifungal activity against several fungi.

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.

In this study, researchers identified key genes such as EDNRB2, GPNMB, TRPM1, TYR, and DCT that regulate melanin deposition in the breast muscles of black-boned chickens, contributing to their unique pigmentation during embryonic development.

This review discusses key molecular targets in cosmetic research and reports no clinical results; it highlights the role of telomerase, sirtuins, and tyrosinase in anti-aging and depigmentation strategies.

This study evaluated a hair mask containing rice germ oil GX-N and ferulic acid on damaged hair and found that rice germ oil GX-N improved hair characteristics after bleaching, UV, and heat exposure, but adding ferulic acid did not provide extra benefits.

This study found that scalp cooling resulted in visible hair retention in 53% of breast cancer patients undergoing Epirubicin/Cyclophosphamide and Paclitaxel treatment, with factors like hair bulb diameter, shaft diameter, and anagen rate significantly predicting outcomes.

In this study, repetitive subcutaneous administrations of a conditioned medium from stem cells significantly suppressed hair graying in mice exposed to X-ray irradiation, likely through antioxidative mechanisms involving HGF and potentially VEGF.

In this study, a bleaching protocol was developed to evaluate hair repair products, revealing that K18® and Olaplex® improve hair brightness and lightness, with distinct impacts on hair fiber properties.

This study explored the potential of human hair keratin as a filtration material, finding that it may effectively absorb the pollutants diclofenac and perfluorobutanesulfonate. The researchers reported significant binding affinities through molecular simulations, supporting further investigation into keratin's use for water purification.

In this study, the researchers found that measuring tacrolimus levels in scalp hair could be a reliable method for monitoring drug exposure in kidney transplant recipients, offering an alternative to frequent blood tests by utilizing self-collected hair samples.

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.

This study developed a biocompatible hair-dyeing technology using a dark polyphenol complex, which demonstrated effective hair coating, improved mechanical strength, and strong antioxidant properties while maintaining high cell viability.

This paper discusses strategies for creating sustainable cosmetic emulsions, highlighting the use of food waste, fermentation processes, and low-energy emulsification methods to minimize carbon footprint while preserving the bioactive properties of raw materials.

This paper reviews the surface degradation of hair and describes how combining 18-MEA with specific surfactants can maintain hydrophobicity on bleached and weathered hair surfaces.

This article discusses the updated European Training Requirements for the specialty of Dermatology and Venereology, emphasizing the harmonization of curriculum to improve specialist training across Europe, and reports no new clinical results.

This review highlights the potential of nanotechnology-based formulations in hair care and treatment, emphasizing how these innovative materials can enhance the stability, efficacy, and safety of active compounds while addressing the limitations of conventional formulations.

This study reported that frontal fibrosing alopecia predominantly affects postmenopausal women and identified potential risk factors like frequent β-blocker use and sunscreen application, indicating the need for further research.

This review found that while forensic DNA phenotyping and health applications for pigmentation genetics show potential, factors like phenotype definition and population diversity present challenges to accurate genotype-to-appearance predictions.

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.

In this study, the SFE-4 extract from coffee pulp demonstrated potential effects for treating androgenetic alopecia by enhancing cell proliferation and gene expression related to hair growth pathways in vitro, using human hair follicle dermal papilla and prostate cancer cells.

This review highlights the possibility of safely altering hair color through innovative cosmetics by targeting key biological processes in hair follicles, using insights from mammalian pigmentation studies and drug-induced hair color changes as potential pathways.

This study found that split-head paired design trials are as effective as whole-head parallel design trials in differentiating anti-dandruff shampoos through scalp flaking measurements, but are more efficient and cost-effective, requiring fewer participants to achieve similar results.

This study found that specific dermoscopic signs, such as diameter diversity of leukotrichia and Pohl-Pinkus constrictions, were associated with progressive vitiligo, and early-stage melanin synthesis was impaired in vitiligo-associated leukotrichia.

This review evaluates the literature on the ethnopharmacology, phytochemistry, and therapeutic potential of Darmana Turki (Artemisia maritima L.) and reports no new clinical findings.

This review discusses the properties and bioextraction methods of chitin and chitosans, emphasizing their potential use in eco-friendly cosmetic manufacturing and reports no new experimental findings.

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.
