This study found that using cationic and non-ionic polymers during alkaline hair relaxer treatments may help strengthen hair and control swelling, potentially reducing damage.

Hair straightening methods have advanced to improve effectiveness and reduce damage, but still rely on heat and chemicals.

This study found that rebonding hair straightening treatments visibly damage the hair cuticle, causing surface erosion and cracks, as shown through Scanning Electron Microscopy analysis.

Hair styling products can damage hair over time.

In this study, researchers found that patients with Friedreich's ataxia exhibited more pronounced ultra-structural hair alterations compared to carriers, likely due to oxidative stress related to deficient frataxin expression.

In this study, researchers found that chemical treatments like bleaching can cause severe damage to the hair cuticle, with previously modified hair showing complete deterioration compared to the partial degradation seen in virgin hair, highlighting the need for mindful cosmetic practices.

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

Hair dye can cause serious scalp issues, including skull erosion.

This study presented a case of tinea capitis in a 4-year-old without typical symptoms and traced the infection to Microsporum canis carried by domestic cats, highlighting the need for accurate diagnosis and appropriate treatment, especially in households with pets.

Mutations in the DSG4 gene cause specific hair and scalp issues.

This study found that peroxide-rich plasma-activated water caused minimal morphological damage to hair, while nitrate-rich plasma-activated water induced significant damage, especially in porous hair types.

This study reported that fermented grapeseed oil may enhance hair permeability and improve strength and color retention in chemically treated hair compared to regular grapeseed or silicone oils.

This review summarizes recent findings on scalp involvement in pemphigus vulgaris and pemphigus foliaceus, highlighting diagnostic methods and their underlying histopathological, immunopathological, and clinical features, but reports no new clinical results.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

This chapter reviews the anatomy and structure of hair, discusses hair damage and analyses, and explores methods for processing hair changes, but presents no new research findings.

This article discusses the characteristics of human hair, its damaging processes, and the potential repair effects of immuno-cosmeceuticals, but it reports no new clinical results.

This review examines the science and technology behind temporary and permanent hair straightening, discussing the processes, potential advancements, and considerations for reducing adverse effects, but does not report new research findings.

This review discusses the genetic factors involved in hair follicle morphogenesis and cycling and reports no new clinical results; it emphasizes the role of genes in hereditary hair diseases.

This article reviews major types of genetic hair shaft defects and associated syndromes, emphasizing understanding histologic features and diagnostic methods, but reports no new clinical findings.

This review identifies genetic mutations associated with congenital hair loss disorders in Japanese populations, particularly highlighting common LIPH gene mutations linked to woolly hair/hypotrichosis, and reports no new clinical results.

This study shows that environmental contamination affects mummy hair, suggesting that using it to assess ancient people's health or nutrition should be approached cautiously.

This paper reviews the genetic aspects of hair disorders and suggests that understanding these genes could advance treatment and diagnosis; it reports no new experimental findings.

This study of African-American women found that those perceiving greater hair breakage showed lower break stress and higher premature failure rates, linked to grooming practices and hair curvature.

This study identified a missense mutation in the keratin 71 gene as the cause of autosomal dominant woolly hair/hypotrichosis in a Japanese family, marking the first human mutation in KRT71 linked to a hair disorder.

This study developed a reliable RP-HPLC-DAD method, finding that amino acid concentrations in bleached hair decrease with higher hydrogen peroxide levels, notably affecting cystine.

The document explains the genetic causes and characteristics of inherited hair disorders.

Genetic mutations cause various hair diseases, and whole genome sequencing may reveal more about these conditions.

The document concludes that diagnosing and managing plaque psoriasis, particularly in sensitive areas, is challenging and requires careful differentiation from similar skin conditions.

This study introduced a novel, weakly supervised method for segmenting hair in Scanning Electron Microscope images using simple image-level annotations, achieving over 30% improvement in mean Hausdorff Distance compared to Unet and SAM, while enhancing interpretability and refinement.

In this report, two adult cases of tinea capitis with unusual symptoms like pustules and non-scarring alopecia were diagnosed based on clinical and pathological findings, and successfully treated with oral Griseofulvin and topical luliconazole cream.
