This chapter describes the functions and purposes of hair care cosmetics, including shampoos, hair growth promoters, and grooming products, without reporting new experimental findings.

This study found that αvβ6 integrin inhibits keratinocyte proliferation during wound healing and hair regeneration, suggesting its downregulation may enhance recovery and influence epidermal stem cell behavior.

This case report describes a hair structure abnormality associated with iron deficiency anemia, which improved after iron supplementation ceased hair loss and corrected the hair shaft abnormality.

This review discusses experimental data, technologies, and genetic factors related to stem cell niches, highlighting their role in tissue regeneration and diseases, but reports no new results.

This article discusses the coordinated roles of different epidermal stem cells and other cell types in the skin's wound healing process and reports no new experimental results.

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.

This article addresses the need to screen for nutrient deficiencies in patients with hair loss but reports no new findings, noting that supplementation without deficiency may not be beneficial and could pose risks.

This review discusses how changes in hair and skin may indicate underlying vitamin deficiencies and emphasizes the need to identify populations at risk for these deficiencies; it reports no new results.

This review discusses feline dermatophytosis and emphasizes the importance of early detection and appropriate treatment, but it reports no new clinical results.

Oral retinoids are effective for severe skin conditions but require careful use due to side effects.

This review discusses the molecular mechanisms of Hutchinson-Gilford progeria syndrome and evaluates current research trends, available mouse models, and prospects for developing therapies, but reports no new clinical findings.

This article reviews various topics discussed at a workshop on hair disorders, focusing on hair biology, diagnosis, and challenges in therapy evaluation, without presenting new clinical findings.

This review discusses the side effects and diseases related to hairstyles and hair treatments among black women, highlighting the need for thorough examination by dermatologists, but reports no new clinical results.

In this study, Meis1 was found to regulate epidermal homeostasis and act as a proto-oncogenic factor in skin tissues, with differences in expression patterns between normal and tumor cells.

This study found that using a non-invasive multielectrode array for gene electrotransfer in hairless guinea pigs increased gene expression in the epidermis significantly, with minimal skin changes observed.

The document concludes that correct diagnosis of alopecia types is crucial, scalp biopsies are important, and more research is needed.

This review discusses environmental factors like UV radiation and smoking that affect hair health and highlights the potential role of nutrition, but it reports no new results.

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

This study identified a novel homozygous EDNRA variant linked to Oro-Oto-Cardiac Syndrome and showed that EDNRA signaling is essential for normal craniofacial and cardiovascular development.

This study found that the presence of Malassezia fungi in the scalp's hairy roots was more pronounced in individuals with androgenetic alopecia than in healthy controls, suggesting a potential link to the condition.

This review discusses surgical and non-surgical options for hair restoration in burn alopecia, highlighting follicular unit extraction and transplant as preferred methods but reports no new clinical findings.

This review discusses factors influencing hair pigmentation and the etiology of canities, noting the lack of clarity in underlying mechanisms and calling for further research on treatment options.

This study suggests that TGF-alpha may function in an autocrine or juxtacrine manner rather than promoting cell proliferation during hair growth cycles in ferrets and sheep.

Hidradenitis Suppurativa is a chronic skin condition best treated early with surgery for better outcomes and less recurrence.

This review discusses the potential benefits of using natural permeation enhancers to improve transdermal drug penetration in formulations like emulgel, a promising topical delivery system for hydrophobic drugs.

This review explores how herbal hair oils made from ingredients like amla and hibiscus may offer benefits such as reducing hair loss and dandruff, but these are summarized from existing research rather than new experimental data.

The document discusses various public health initiatives and societal issues, emphasizing early intervention and support.

In this study, researchers observed that trichocytic and epithelial cytokeratins have distinct expression patterns within various human and bovine hair follicle cells, contributing to understanding hair follicle development and growth.

This study observed that human hair macrofibrils predominantly exhibit a double-twist architecture with varying inter-macrofibril angles, advancing insights into their structural organization and mechanical implications.

In this study, researchers created a mouse model using CRISPR/Cas9 technology to investigate hypotrichosis simplex and woolly hair, finding that Krt71-knockout mice exhibited curly hair and developed complete hair shedding without immune deficiencies, mimicking conditions seen in humans and potentially aiding future hair disorder research.
