Hair shaft disorders often indicate genetic or systemic issues and are managed by minimizing damage.

This study explains the formulation and evaluation of a natural polyherbal shampoo, which effectively colors hair and provides conditioning without the dermal and systemic toxicity risks of synthetic dyes, offering an effective alternative to conventional products.

This study highlights that polycystic ovary syndrome develops through genetic and environmental factors, with insulin resistance as a key mechanism, impacting the risk of metabolic and cardiovascular conditions.

This review assessed the role of scalp hair Survivin protein in individuals with premature graying, exploring its potential involvement in graying-related processes and highlighting its overexpression in autoimmune diseases that may influence the survival of specific immune cell clones.

In this study, researchers used synchrotron X-ray imaging to examine rat vibrissa follicles, finding that despite variations in vibrissa length and follicle size, certain sensory structures remain consistent, suggesting specialized roles in sensory processing depending on the vibrissa type.

This study reviewed literature on hair growth and found that external factors like pollution, stress, and nutrition can adversely affect hair, concluding that a multifactorial approach and personalized nutrition monitoring are essential for effective hair loss therapy.

In this study, researchers developed and tested a herbal hair serum using hibiscus, flaxseed, and aloe vera, finding that the optimal formulation effectively reduces frizz, enhances hair smoothness and glossiness, and provides moisturizing benefits without harmful ingredients compared to conventional hair serums.

This study highlights how examining hair histology under a microscope helps forensic analysts identify animal species by distinguishing specific microscopic features, which supports accurate reference database creation and aids crime scene investigations.

This study found that hair with lower levels of keratin associated proteins reduced the foreign body response in mouse subcutaneous implant tests compared to hair with higher keratin levels.

This study found that undiluted mint leaf extract effectively inhibited multidrug-resistant Staphylococcus aureus and killed Culex pipiens larvae, suggesting its potential as a biocontrol strategy around hospitals.

This study explores how Dhatryadi rasayana, a polyherbal formulation with antioxidant properties, may help prevent and treat premature hair greying by addressing factors such as oxidative stress, nutritional deficiencies, and hormone imbalances, potentially through rasayana therapy.

This study found that a mixed extract of N. jatamansi, O. basilicum, and C. sativus, particularly when extracted via steaming and ultrasonic methods, increased antioxidant content, stimulated melanin production for black hair, and promoted hair growth in mouse models, while maintaining high cell viability.

This review discusses the potential risks of formaldehyde in hair keratin treatments like Brazilian blow-dry, and reports no new clinical results; it emphasizes the need for greater safety assessments including occupational exposure.

This case report describes a 1-year-old Yorkshire terrier presented with persistent alopecia and seborrhea in dark-haired areas, with no signs of hair regrowth despite treatment for folliculitis and seborrhea.

This case series describes seven distinct hair shaft disorders, highlighting the importance of accurate diagnosis since these conditions are often treated incorrectly as alopecias without improvement.

This study suggests that typical skin lesions in Carney complex may originate from the pro-melanogenic activity of a specific dermal fibroblast population influenced by PKA signaling.

This review discusses recent advances in the understanding of follicular melanogenesis and its pathological changes, particularly how these changes are associated with specific disease phenotypes, but it reports no new results.

This study found that canine hair follicle stem cells are located in the isthmus/bulge region of the hair follicle, surrounded by telocytes.

This review discusses the genetic disorder, monilethrix, characterized by fragile, brittle hair and its inheritance patterns, and reports no new clinical results.

This study found that fish oil supplementation in male Wistar albino rats helped maintain hair shaft structure and improved amino acid composition, while reducing harmful protein compounds associated with diabetes and hypercholesterolemia.

This review discusses the evolving understanding of epithelial stem cells, noting how new models challenge old assumptions and suggesting multiple stem cell populations contribute differently to skin and hair follicle regeneration.

The document concludes that different types of hair loss have specific treatments, and early diagnosis is crucial for preventing permanent hair loss.

This comprehensive review analyzes androgenetic alopecia treatments, discussing the mechanisms, costs, efficacy, and safety of FDA-approved drugs like minoxidil and finasteride, as well as newer non-FDA-approved options that have shown effectiveness across various studies.

This review discusses the potential of single cell technologies to improve understanding and treatment of impaired wound healing and reports no new clinical results.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

This article reviews the multifunctional roles of calreticulin outside the ER and highlights its impact on wound healing in animal models, but reports no new clinical results.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This study found multipotent progenitors in sweat ducts that become unipotent after sweat gland development, highlighting distinct regenerative capabilities in adult glandular skin stem cell populations.

This review explores the evolution and development of skin-associated adipose tissue and proposes new nomenclature for the cells and adipose tissue underlying the reticular dermis, without reporting clinical results.

Keratins are crucial for cell structure, growth, and disease risk.
