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 study observed that pigmented casts are present in various alopecia types but are not specific to any single diagnosis, with distinct morphological features noted in trichotillomania.

This case report describes subcutaneous emphysema in a patient's forearm as a rare complication of liquid nitrogen spray used on hypertrophic actinic keratosis, resolving spontaneously within a day.

This review discusses the role of hair microscopy in diagnosing alopecia, stating that while it excludes diagnoses related to hair breakage, it only confirms nonspecific short anagen in alopecia cases.

This article reviews the use of the transtemporal approach for midface and lower eyelid-cheek junction rejuvenation, detailing surgical techniques, post-operative care, and potential complications, but reports no new clinical results.

The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.

This study observed that mTORC1 signaling is activated and crucial for hair follicle regeneration and hair growth in irradiated mice, facilitating recovery within 96 hours without significant hair loss.

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 case report describes a 23-year-old woman who experienced hair breakage along her anterior hairline due to the formation of bubbles in the hair shafts from blow-drying techniques.

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 found that PBX1 overexpression reduces hair follicle-derived mesenchymal stem cell senescence and apoptosis by alleviating ROS-mediated DNA damage, rather than enhancing DNA repair.

This study found that single-dose x-ray irradiation in rat calvaria skin led to morphological changes in collagen fibers, disorganization, and a temporary absence of sebaceous glands and hair follicles.

This article discusses laboratory and physical markers that may help detect androgenic anabolic steroid abuse in athletes and reports no new primary research results.

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.

This article reviews historical approaches to electrolysis for permanent hair removal and suggests improvements in equipment, but reports no new clinical results.

This review discusses skin problems common among long-distance runners and outlines helpful treatments, without presenting new clinical results.

This report describes two rare cases of desmoplastic melanoma presenting as alopecia neoplastica, highlighting a potential diagnostic pitfall for clinicians examining patients with scar-like alopecia.

This article discusses the mini-lift as a cosmetic procedure for minor cheek and neck laxity, emphasizing its benefits like quicker recovery and minimal incisions, but provides no new clinical data.

This article discusses various techniques to achieve a cosmetically attractive single donor scar in hair restoration surgery, reporting no new clinical findings.

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 study presents a novel optical microscopy technique showing that biomagnetic fields in hair follicles can interact with those in blood, affecting magnetic profiles until catalase breakdown.

This case report details an instance of acute kidney injury following the inhalation of hair dye during a hairstyle session.

This article presents a rationale for using a combination of follicular units and slit grafts in hair transplanting and reports no new clinical results.

This study found that L-cystine-modified rabbit hair fibers had improved dye adsorption and spinnability, due to changes in secondary structure and surface characteristics.

This study found that oral zinc sulphate appeared effective and safe for treating thallium poisoning, particularly in reducing hair and skin symptoms and mitigating its severe progression in patients.

This report discusses a request for a health hazard evaluation at Equifax in St. Petersburg, Florida concerning potential workplace exposures related to reported employee health issues, particularly hair loss, but provides no new results.

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.
