In this study, tresses treated with pH 1.0 acid straightener showed better straightening but more damage to hair properties compared to those treated with pH 2.0.

This study proposed a new standardized in vitro framework using human hair tresses to evaluate cosmetic hair product performance and found significant improvements in hair breakage, tensile strength, shine, volume, and frizz control compared to a control group without such changes.

This study found that the shampoo formulation with Polyurethane-14 and AMP-acrylates copolymer improved curl definition and reduced frizz and volume in natural and curly hair tresses compared to the control.

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.

Adjusting hair dryer settings improves drying efficiency and keeps hair healthy.

This study found that after using Mintop Shampoo for 10 wash cycles, significant improvements in hair detangling, combability, static reduction, shine, softness, smoothness, bounce, tensile strength, and percentage elongation were observed compared to the initial damaged state.

This study developed mathematical models showing that heat penetrates individual hair quickly but takes longer to reach the center of hair bundles, helping understand potential damage from high-temperature styling tools.

This in-vitro study reported that a luliconazole-based formulation improved hair cuticle integrity and was more effective than ketoconazole in repairing damaged hair after 5 and 10 washes, with sensory analysis supporting these results. Further human studies are needed to confirm its clinical effects.

This study found that hair care formulations containing vegetable oils like Brazil nut and olive oil improved hair strength, shine, and combability more effectively than those with silicone.

This study found that pre-treating hair with argan oil reduced protein loss and provided protection against oxidative damage, supported by both ATR spectrum analysis and protein measurements.

The conclusion is that a new method to measure hair shine was confirmed to match people's visual assessments.

This study found that formulations containing pequi and buriti oils improved texture properties and significantly increased gloss in curly hair, with pequi oil also significantly enhancing tensile strength.

This review summarizes causes and treatments of androgenetic alopecia with a focus on herbs as potential alternatives, but reports no new results and suggests more research is needed to validate these options.

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 innovations in hair cosmetics, focusing on esthetic procedures and products in the Indian market, and reports no new experimental findings.

The article concludes that the global hair trade is exploitative and reflects complex cultural and economic issues.

This article reviews the impact of UV radiation and visible light on human hair structure and summarizes protective strategies, reporting no new clinical results.

This study found that higher concentrations of copper (II) ions in human hair increase protein oxidative modification, contributing to hair damage regardless of UV exposure and pigmentation level.

This study found that thermal hair-straightening devices significantly damaged the cuticle and cortex of virgin Asian and Caucasian hair, with Asian hair experiencing more protein loss than Caucasian hair.

Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.

This review outlines the current regulatory framework for cosmetics under the FD&C Act, highlighting that they are less strictly regulated than drugs, but notes potential future changes due to proposed legislations requiring stronger safety measures.

This study found that non-ionic silicone emulsion best protected hair color from UV-induced fading, outperforming honeysuckle extract and benzophenone-3, with significant effects in both dyed and virgin hair.

The study developed herbal shampoo formulations using isolated phytoconstituents, such as eugenol, rutin, menthol, and camphor, which demonstrated similar antifungal efficacy to ketoconazole but with improved safety and detergency, offering a promising alternative for managing seborrheic dermatitis.

In this study, researchers developed and assessed two polyherbal hair tonic formulations, finding that Hair Tonic A containing 10% white tea extract improved hair thickness, manageability, and anti-frizz properties, particularly for blonde and black hair, while demonstrating greater stability compared to Hair Tonic B.

This study aims to develop and evaluate herbal shampoo powder made from natural ingredients, focusing on its efficacy in removing debris and dandruff, enhancing hair development and shine, and strengthening and darkening hair. Results are not reported.

This study tested the effects of protective pre-treatments on African hair and found that these treatments, combined with moderate grooming, may help maintain cuticle integrity.

This study assessed three materials—L-arginine, hydrolysed keratin, and cystine-silanol copolymer—ex vivo for their potential to reduce undesirable effects of hair bleaching, such as damage to hair proteins.

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.

Certain ingredients can help protect hair color.
