This review discusses the potential risks and effects of chemical relaxers on hair and scalp health, reporting no new clinical results; the authors emphasize dermatologist guidance to mitigate these issues.

This review suggests that standardized herbal shampoos may offer a safe and sustainable alternative to synthetic products due to their natural saponins and multifunctional benefits, though challenges in consistency and shelf-life persist.

This article reviews the composition and functionality of shampoos, emphasizing the role of surfactants in cleaning and conditioning hair, and reports no new experimental results.

This study developed plant-pigment-based shampoos using extracts from Neem, Fenugreek, Hibiscus, and Butterfly Pea, which demonstrated stability, antimicrobial properties, and potential scalp benefits such as hair growth promotion and dandruff reduction, making them a promising alternative to synthetic dyes.

This article discusses the complexity of selecting hair cleansing products and conditioners and reports no new scientific findings or results.

Human hair structure varies by ethnicity, and certain treatments can improve hair condition and appearance.

Twisting hair weakens it, but strength can be recovered at low twist levels.

This study developed and tested a shampoo with semi-permanent dyes designed to gradually cover gray hair, reporting maintained stability and effective gray–black coloration on high-canities hair tresses through eight wash cycles.

This paper discusses the use of Digital Volumetric Imaging with fluorescent dyes to visualize and compare the interior structures of six different virgin hair types, reporting no new clinical results.

A new method helps understand hair shine and various products improve hair care.

This review examines hair cosmetics, including shampoos and conditioners, for their formulations and effects, but reports no new clinical findings; it emphasizes the importance of dermatologist knowledge in treating diverse hair conditions.

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 review discusses the components and effects of various hair cosmetic procedures and explores new techniques like camouflage methods and tattoo scalp, without reporting new clinical results.

This study highlights that improving medical professionals' knowledge of hair cosmetics can enhance patient adherence to alopecia treatments and reduce health risks from incorrect use of hair products.

This study suggests that Thyroxine (T4) may promote key features of human skin wound healing, such as re-epithelialization and angiogenesis, in an ex vivo model.

This article discusses hair care practices and hair cosmetics in managing alopecia but reports no new clinical findings; it emphasizes the importance of scalp health and good patient-physician communication.

This review article examines current drugs for androgenetic alopecia, focusing on their mechanisms and clinical efficacy, noting that while finasteride and minoxidil are commonly approved treatments, new drugs targeting different pathogenic pathways have emerged, offering a broader understanding and reference for AGA treatment options.

This article discusses a novel hypothesis on the role of hair follicles in dandruff pathogenesis, focusing on immune response and inflammation due to scalp microbiota changes and sebum by-products, but reports no new clinical results.

This study found that a combination of vitamins in hair care products promoted hair shaft elongation in a mouse model by activating the PlGF/VEGFR-1 signaling pathway.

This review identifies 1859 plant and fungal species from the Pantanal and highlights patents, mainly from South Korea, focused on extracts with antitumoral, anti-inflammatory, and cosmetic applications, but reports no new clinical results.

In this study, researchers highlighted that while hair lipids are crucial for hair health and protection, surfactants in shampoos and conditioners can partially remove these lipids, potentially affecting hair structure, though the exact mechanisms remain poorly understood and require further investigation.

This study verified that a new straightening process involving a flat iron, ammonium thioglycolate, and hydrogen peroxide may permanently straighten wavy hair by eliminating disulfide bond distortions.

This article reviews the relationship between scalp conditions and hair health, suggesting that shampoos with Malassezia inhibitory agents may help reduce premature hair loss, but it presents no new clinical results.

This source summarizes discussions by an advisory board of twelve experts on hair loss, focusing on heredity, aging, and environmental impacts, and emphasizing strategies that may slow alopecia.

In this study, researchers found that using 0.75% aspartic acid as an intermediate agent for a permanent wave improved wave formation and retention compared to a control in virgin hair, also reducing cuticle damage and maintaining tensile strength.

Hair properties change under electromagnetic fields and are influenced by individual characteristics and the environment.

This review discusses the potential role of oxidative stress in hair graying and age-related alopecia, emphasizing the need for new strategies to counteract these effects, but reports no new results.

This study found that a single application of 'Lye' or 'No-Lye' chemical straighteners significantly reduced drug concentrations in hair samples from both drug-fortified standards and authentic drug users.

This article reviews the current practices and interpretations of research data on permanent waving and hair straightening, but does not present any new research findings.

This study observed that adult Netherton syndrome patients showed a range of normal to diminished immune responses to polysaccharide, conjugate, and mRNA-based vaccines, with responses generally overlapping those of healthy controls, suggesting no consistent B- or T-cell immunodeficiency in this population.
