This study found that citric acid treatment can significantly improve the structural integrity and mechanical properties of chemically treated hair, reducing damage by increasing keratin crosslinking density and decreasing crystallized calcium soaps, with varying effectiveness depending on the type of chemical treatment.

This study found that using 369LAB Lipid Bond, derived from plant oil triglycerides, can restore lipid content in damaged hair to natural levels and improve hair strength, integrity, and resilience after a single application, with benefits persisting even after discontinuation.

In this study, the researchers explored a hair dye gel formulated with Indonesian native plant extracts and found it produced stable brown shades on bleached hair, with the most preferred dark brown achieved at a 12% concentration, and showed no skin irritation.

Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.

Different oils affect hair flexibility and strength, with their impact varying on whether hair is virgin or bleached.

In this study, researchers examined juglone's potential as a restoring agent for hair keratin damaged by permanent or bleaching treatments, finding that juglone formed Michael adducts with cysteine residues, leading to a more regular hair surface as observed via IR spectroscopy and SEM analysis.

This study found that the newly developed hair product K-30 increased both protein content and weight in chemically damaged hair to levels similar to healthy hair, unlike traditional products that only temporarily improve texture.

This review discusses various techniques for depigmentation in vitiligo patients and suggests that cryotherapy, performed by an experienced professional, may be the most cost-effective and accessible method.

This study quantified the effects of chemical treatments like oxidative bleaching and hair relaxing on the movement characteristics of hair strands using a novel high-speed recording method.

In this study, carboxymethylalanyl disulfide keratin was shown to effectively prevent hair damage during repeated bleaching and permanent waving treatments.

Hyperpigmentation is common in pregnancy and may not fully fade after birth; melasma, also frequent, can persist but has limited treatment options during pregnancy.

This study found that treatments like abrasion, bleaching, and CETAB application affect hair fiber shear modulus differently, with moisture levels notably impacting bleached fibers more than untreated ones.

This review highlights that hair care products can cause adverse effects like irritation dermatitis and allergic contact eczema but does not report new clinical findings.

This review discusses the need for an updated 'European hair cosmetic series' to include common contact allergens and remove outdated substances based on current evidence and regulations, but it reports no new results.

This narrative review discusses adverse reactions associated with hair care products, specifically irritation dermatitis and allergic contact eczema, and suggests the need for attention to common allergens like PPD, GMTG, and ammonium persulphate.

This case report describes a woman who developed green hair due to high copper levels in swimming pool water, exacerbated by hair treatments and inadequate water replacement.

This study demonstrates that a bioinspired peptide, PepACS, can efficiently and safely perm hair by interacting with keratin's sulfhydryl group without compromising tensile strength, and it shows potential for hair repair and dyeing applications in the hair care industry.

This study found that testosterone concentrations in hair samples were moderately stable over three months, with cosmetic treatments like coloring increasing testosterone levels, while natural hair color in untreated hair did not affect testosterone measurements.

In this study, human hair-carboxymethylated protein analysis showed that weathering for over 2.5 years can obscure electrophoretic patterns, while cosmetic treatments did not cause significant changes.

This supplement reviews various presentations on African hair and skin research from a L’Oréal workshop, reporting no new clinical results but highlighting the need for better education and prevention measures against harmful skin bleaching practices.

This study highlights the necessity for regionally tailored dermatology guidelines in Africa, given that existing international guidelines often overlook the continent's unique dermatological challenges, such as diverse skin presentations, cultural practices, and limited healthcare resources.

This article reviews the variations and risks associated with skin conditions in melanin-rich individuals, including assessment challenges and complications from common skin treatments, but presents no new research findings.

This study found that 10% carbamide peroxide significantly reduced acne lesions compared to a vehicle solution, suggesting it as an effective and safe alternative to benzoyl peroxide for treating mild to moderate acne.

This study found that torsional measurements can effectively distinguish the effects of hair care products on the cuticle versus the cortex of hair fibers, unlike tensile measurements.

This study found that bleach treatments significantly increased hair surface roughness and decreased Young's modulus, indicating marked changes in hair's molecular structure which may affect future hair-care product formulation.

This study found that a bleach bath treatment with 0.005% HOCI reduced the expression of certain serine proteases in cultured keratinocytes and lowered skin pH in atopic dermatitis patients, potentially improving symptoms by modulating the NF-kB pathway.

This promotional content discusses hair transplant options in Deerfield Beach City, Florida, and advises against certain methods, but it reports no research findings or clinical results; readers are encouraged to call a specialist for more information.

This paper reviews the surface degradation of hair and describes how combining 18-MEA with specific surfactants can maintain hydrophobicity on bleached and weathered hair surfaces.

This study found that keratin derivatives with functionalized thiol groups improved binding to both natural and bleached hair fibers, suggesting a promising strategy for enhancing keratin's durability in hair repair.

This study found that using poly(ethylene imine) as a counterion reagent improved the colorability and shampoo fastness of bleached human hair when dyed with an acid dye.
