This study found that higher concentrations of copper (II) ions in human hair increase protein oxidative modification, contributing to hair damage regardless of UV exposure and pigmentation level.

This review discusses the pathogenesis of common sebaceous gland diseases and their molecular pathways, but it reports no new clinical findings.

This review evaluates neck rejuvenation techniques, including cervical rhytidectomy, and discusses potential surgical complications, without presenting new clinical findings.

This review discusses the impact of various external factors like cosmetics, traction, and radiation on hair health and color, but reports no new findings.

This study found that keratin film from human hair samples responded to damage from UV, bleaching, perming, and thermal treatments, making it a useful model for evaluating hair damage in product development.

This study demonstrated that combining l-cystine and thiamin in a formulation may protect against UV-induced damage in growth-limited human epidermal keratinocytes in vitro.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

This study reports that a 100% herbal hair dye composed primarily of Cymphomandra betacea, Tagetes erecta, and Aloe vera gel provides permanent hair color without causing hair damage, loss, or skin irritation compared to synthetic dyes.

This article discusses the genomic and postgenomic changes in chronic degenerative diseases and cardiovascular and skin disease contexts, highlighting potential modulation through diet and pharmacological interventions without presenting new experimental results.

In this study, researchers found that UV radiation causes hydroxy radicals to form cuticle holes specifically between the cuticle layers in wet hair, unlike random holes caused by Fenton's reaction.

This study found that IPL hair reduction led to significant decreases in hair count and thickness by promoting hair follicle miniaturization, increased telogen phase, and reduced cell proliferation.

This study observed that regular coconut oil users have significantly reduced hair irregularities compared to non-oil users, as quantified by a new "hair protection factor" metric, highlighting coconut oil's potential in minimizing hair damage.

This chapter defines skin integrity as a blend of intact structural elements and adaptable functional capacity, highlighting its importance in maintaining skin health across various conditions but reports no new research findings.

This study found that premature greying of hair was reported in 42.5% of young adults from King Faisal University, with higher prevalence among females, and noted associations with various health and lifestyle factors.

This study suggests that low proliferation rates in bald areas of androgenetic alopecia patients, along with persistent inflammatory infiltrate, may lead to follicular miniaturization and fibrosis.

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 article reviews the diagnostic process for hair problems, emphasizing the importance of thorough patient evaluation and communication but reports no new clinical results.

Up to 50% of scalp hair can be lost before it appears thin, and treatment is only needed for hair loss caused by diseases or deficiencies.

This article discusses the range of skin-related side effects caused by chemotherapy and radiotherapy, including novel patterns emerging with targeted therapies, but does not report new clinical results.

This review discusses approaches to diagnosing and managing cutaneous manifestations of lupus erythematosus and reports no new clinical results.

This study reports that discontinuing blow drying improved hair loss in two women with vacuolization in their hair shafts, suggesting a potential link between heat styling and alopecia.

This study reviewed 54 articles to examine how continuous exposure to air pollution causes hair damage, hair loss, and scalp conditions due to oxidative stress and inflammation, and highlighted anti-inflammatory substances that could mitigate these effects.

This study reports that cutaneous manifestations such as herpes zoster, purpura, and livedo reticularis in COVID-19 patients can potentially indicate disease severity, aiding in the prediction of the illness's progression and guiding dermatological management during the pandemic.

This study found that while participants in Jeddah, Saudi Arabia, had good knowledge about Vitamin D and recognized sunlight as a key source, there was inconsistency in their attitudes towards maintaining adequate Vitamin D levels.

In this study, researchers found that using 0.75% aspartic acid as an intermediate agent for a permanent wave improved wave formation and retention compared to a control in virgin hair, also reducing cuticle damage and maintaining tensile strength.

This study found that prolonged use of finasteride in women led to altered levels of sex steroids, DNA damage, and increased menstrual bleeding, suggesting adverse health effects without clear benefits for androgenetic alopecia treatment.

This review discusses the similarities between wound healing and embryonic development, focusing on signaling pathways and their potential for developing new wound healing strategies, and reports no new clinical results.

Chemotherapy can cause skin side effects that affect patients' lives, but they can be managed to avoid interrupting cancer treatment.

This chapter provides an overview of skin physiology, aging effects, and how environmental factors like UV damage impact skin health, without presenting new research findings.

This study found that treating human hair with vitamin E and γ-oryzanol significantly reduced UV-B-induced structural damage, with γ-oryzanol providing greater protection, especially in female hair samples. The findings highlight these compounds' potential as cost-effective solutions for preserving hair integrity against UV damage.
