This study suggests that elevated levels of certain heavy metals, rather than zinc, may play a causative role in primary chronic telogen effluvium.

This study identified that copper depletion in dermal papilla cells reduced hair growth by boosting ROS levels, but ROS scavengers like NAC and ascorbic acid partially alleviated this effect.

In this study, the researchers synthesized copper-doped mesoporous silica nanoparticles and observed that they enhance tumor microenvironment regulation and, when paired with disulfiram, effectively kill cancer cells while also showing synergistic anti-tumor effects with immune checkpoint inhibitors.

This review discusses recent advancements in nanotechnology-based treatments for chronic wound healing in diabetic models, noting that despite promising results, these innovations have yet to translate into widely available commercial products.

This study found that children with autism spectrum disorder generally have lower levels of both essential and toxic trace elements in their hair compared to controls.

This study found that shampoo and conditioner do not alter hair's molecular structure, while perming treatments significantly affect keratin and intermediate filament structures due to bond alterations.

This consensus paper reviews expert opinions on treating telogen effluvium but reports no new clinical findings.

This study reported that a newly developed hydrogel composed of recombinant type I collagen and chitosan, incorporating a metal–polyphenol structure, demonstrated strong mechanical and healing properties, effectively promoting wound healing in a full-thickness skin defect model.

This study found that the combined use of sugarcane fibre and keratinolytic enzymes reduced hairball excretion in cats.

This study observed significant differences in trace element hair-scalp concentrations associated with atherosclerosis in coronary and carotid disease patients, suggesting that zinc levels and lymphocyte count interactions may significantly influence cardiovascular disease development.

This review discusses the role of oxidative stress and reactive oxygen species in the development of androgenic alopecia and reports no new clinical findings.

This study found that Dr. SKS Hair Booster Serum significantly improved hair shaft diameter, terminal hair counts, and hair growth rate in women with PCOS experiencing female pattern hair loss, without any reported adverse events, over a six-month treatment period.

This study found that β-sitosterol, a brain-penetrable phytosterol, reduced melanoma cell growth and brain metastasis formation by interfering with mitochondrial respiration, suggesting its potential as an adjuvant therapy to BRAF inhibitors for patients with melanoma brain metastases.

This study reports that women with hair loss had significantly lower levels of several biomarkers, including hemoglobin, iron, copper, selenium, vitamin D, vitamin B12, folate, and thyroid hormones, compared to healthy controls.

This study found that urinary selenium to creatinine ratio and serum selenium concentrations quickly respond to changes in dietary selenium, making them useful biomarkers for assessing selenium status in dogs.

This study found that senior dogs fed amino acid-complexed and lysine-glutamic acid-complexed trace minerals had longer, faster-growing hair and increased activity compared to those fed inorganic trace minerals.

This chapter reviews the potential of stem cells from discarded deciduous teeth in regenerative medicine and dentistry, with no new clinical results presented.

This study reviews popular over-the-counter hair loss products available online but reports no new clinical results.

This review highlights recent advancements in understanding and treating alopecia, emphasizing genetic and immune factors involved in different forms, and discusses emerging therapies such as gene-editing and exosome-based treatments, though achieving complete hair regrowth remains a challenge.

This study found that laboratory testing practices for alopecia areata vary among international hair experts, with the majority routinely conducting thyroid function and complete blood count tests, yet exhibiting diverse approaches toward testing for other conditions or before prescribing systemic therapy.

In this review, researchers examined the molecular diversity and expression patterns of major skin appendage proteins, like keratins and EDC proteins, in tetrapods, highlighting recent findings in reptiles and birds and identifying knowledge gaps for future research.

This case report describes the first successful use of telitacicept in treating a patient with systemic lupus erythematosus and a history of papillary thyroid carcinoma, suggesting its potential as a therapeutic option for such conditions.

Hair transplantation can improve scars after removing a rare skin cancer.

This review discusses the complexities of diagnosing and treating iron deficiency related to nutritional anemia and hair loss, concluding that routine screening and supplementation for hair loss are not yet supported by sufficient evidence.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

This review presents the practice of using hair bioelement analysis to assess nutritional status or environmental exposure, proposing complex interactions and hypotheses regarding depression and autism but reports no new clinical results.

This review explores the complex biological process of hair graying, highlighting oxidative stress, genetic factors, and interventions like antioxidants and genetic therapy as key aspects affecting the preservation of hair pigmentation.

This chapter provides an overview of the complex chemical and physical structure of the hair surface, detailing how factors like ethnicity, environmental stress, and cosmetic treatments can alter its properties and influence the adhesion of hair care products.

This narrative review found that while AI-based tools in dermatology, particularly for hair disorder assessment, have potential to enhance clinical practice by improving objectivity and personalization, they currently serve mainly a complementary role and face challenges like methodological limitations and data bias.

This review discusses the complex role of the immune system in tissue repair and regeneration, highlighting its positive and negative influences but reports no new clinical findings.
