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.

This review highlights that hair's chemical bonds, particularly disulfide bonds, are not homogeneous, as previously thought, but instead vary in response to different cosmetic treatments, suggesting a need for further exploration of ionic bonds and hydrophobic interactions.

This study found that the PLEE method increased hair protein extraction efficiency threefold and that bleaching hair reduced the coverage of keratin and associated proteins, leading to poorer hair quality, though it did not affect the overall protein identification.

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

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.

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 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.

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.

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

This study found that, compared to oxidative treatments, reductive perm-waving more severely impacts the intermediate filaments in European human hair, while both treatments alter denaturation kinetics in a first-order manner.

In a laboratory study, researchers found that a novel Bioactive Crosslink Repair Complex improved both the protection and repair of chemically damaged hair, enhancing tensile strength, shine, and cuticle alignment when added to bleaching mixtures and leave-in conditioners.

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.

In this study, bond-protecting additives combined with low-volume oxidants were shown to reduce hair damage in fine hair by up to 62% compared to standard bleach methods, offering a safer bleaching approach for colorists working with this hair type.

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 compared the effects of three compounds on structural and sensory benefits for bleached hair when applied with or after bleaching, observing that their application may mitigate bleaching-induced damage.

The claimant sued for negligence after a hair treatment caused harm and distress, and the defendant responded after legal action started.

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.

In this case report, a 42-year-old woman with hypothyroidism showed improvement in symptoms like fatigue and hair loss after following an Ayurvedic regimen including Kunjal Kriya, Yoga, and diet changes alongside her regular medication, though further clinical studies are recommended to validate these findings.

This case report chronicles a three-year journey of long COVID in a previously healthy 26-year-old, detailing treatment trials and near-total remission, but provides no new generalizable data.

This retrospective analysis of male patients undergoing hair restoration surgery for androgenetic alopecia found that postoperative edema was the most common complication, occurring in 42.47% of cases.

This study found that untargeted hair metabolomics analysis detected significantly altered endogenous biomolecules, potentially serving as biomarkers for identifying oxidative cosmetic hair treatments like bleaching.

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 an enzymatic method effectively identified chemical treatments like perming and dyeing by detecting higher degradation in treated hair compared to untreated hair.

This study found that using an aqueous solution of AMPD in hair bleach reduced both hair damage and odor compared to ammonium hydroxide.

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.

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.

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.
