In this study, the researchers observed that ferulic acid and resveratrol effectively protected chemically treated hair from oxidative damage, particularly against protein loss and color degradation, but not cisteine oxydation prevention, and these antioxidants also offered protection against sun-induced damage when used in conditioners.

This study explores premature graying of hair, outlining potential causes such as genetic factors, nutritional deficiencies, and autoimmune disorders, and evaluates various management strategies including nutritional supplements, pharmacotherapy, and addressing underlying conditions.

In this study, the researchers explored a hair dye gel formulated with Indonesian native plant extracts and found it produced stable brown shades on bleached hair, with the most preferred dark brown achieved at a 12% concentration, and showed no skin irritation.

This study observed that in a survey of individuals with scarring alopecia, those using chemical treatments or high-tension hairstyles experienced hair loss and alopecia diagnosis at a younger age, while hair dye use was linked to older age at hair loss onset and diagnosis.

This review identifies specific personal care products and allergens commonly causing allergic contact dermatitis in men, which may improve diagnosis and treatment.

This case study and literature review highlights a chemical burn from hair dye experienced by a 17-year-old girl, resulting in a long-term scalp ulcer. It emphasizes the need for careful consideration of scalp complications and a multidisciplinary treatment approach in hair dye procedures.

In their review, the authors discussed the increasing issue of allergies to hair products, highlighting common allergens such as hair dyes and topical minoxidil, and outlined diagnostic methods and alternatives for those affected, particularly addressing higher risks among hairdressers due to professional exposure.

In this study, researchers found a strong association between premature graying of hair and deficiencies in vitamin D and B12, hypothyroidism, and deranged iron profiles, along with higher stress, altered appetite, smoking, and sleep pattern issues, significantly impacting quality of life.

This study reviews recent advancements in near-infrared organic light-emitting diode (NIR OLED) technologies, focusing on their applications and the diverse luminescent materials used in their emissive layers.

This review presents European expert guidelines for diagnosing androgenetic alopecia across genders but reports no new clinical findings; it emphasizes the importance of trichoscopy for differentiating similar conditions.

This meta-analysis found a significant positive association between frontal fibrosing alopecia and both sunscreen and moisturizer use, with the moisturizer association significant only in males.

In this study, text mining revealed that research on natural materials effective for hair—focusing on growth, damage, and dyeing—has increased since 2001, indicating rising academic interest and exploring trends in beauty-related topics.

This study developed a new quantitative method to measure skin cell turnover in just 4 days, showing it can effectively differentiate skincare product performance and revealing that turnover slows with age but responds more to treatments as people get older.

This study identified 15 Iranian patients with PLEC variants linked to various plectinopathies and highlighted a novel association between a homozygous nonsense variant in PLEC and a rare combination of disorders including EB pruriginosa, muscular dystrophy, and congenital myasthenic syndrome.

Certain ingredients in personal care products, like formaldehyde, oxidative hair dyes, and sulfates, pose health risks and need careful review.
