research The Swelling Behavior of Hair Studied Through the Structural Change of Keratin Protein During the Permanent Waving Treatment

November 2024 in “Biophysical Chemistry”

This study analyzed the swelling behavior of human hair during permanent waving treatment, finding that both the microstructure and macrostructure of intermediate filaments swell simultaneously at the initial stage, and while partially destructed by reduction, they are considerably restored through oxidation.

research The Exposome Impact on Hair Health: Etiology, Pathogenesis and Clinical Features – Part I

4 citations , November 2024 in “Anais Brasileiros de Dermatologia”

This study reviews current research to better understand how various environmental and lifestyle factors, collectively known as the exposome, impact hair health and aging, acknowledging that the detailed mechanisms remain partially understood.

research Antioxidant Properties of Platycladus Orientalis Flavonoids for Treating UV-Induced Damage in Androgenetic Alopecia Hair

June 2024 in “Molecules/Molecules online/Molecules annual”

This study found that Platycladus orientalis flavonoids may reduce oxidative damage and slow melanin degradation in AGA-affected hair, improving its quality.

research Bioinspired Peptides Designed for Hair Perming and Dyeing With Potential for Repair

3 citations , July 2023 in “Acta Biomaterialia”

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.

research Metal Chelation Assisted Deposition of Polydopamine on Human Hair: A Ready-to-Use Eumelanin-Based Hair Dyeing Methodology

63 citations , February 2017 in “ACS biomaterials science & engineering”

In this study, polydopamine emerged as a safe and effective alternative to traditional hair dyes like PPD for dyeing gray hair permanently, showing resistance to detergents and causing less toxicity and hair loss in mice.

research Liposomes in Cosmeceuticals

111 citations , March 2012 in “Expert Opinion on Drug Delivery”

This review discusses the potential use of liposomal formulations to enhance the effectiveness of cosmeceutical delivery through the skin barrier, with no new clinical results reported.

research Hydrogen Peroxide and Monoethanolamine Are the Key Causative Ingredients for Hair Dye-Induced Dermatitis and Hair Loss

34 citations , January 2012 in “Journal of Dermatological Science”

In this mouse study, researchers found that hydrogen peroxide and monoethanolamine in hair dyes may be key contributors to dermatitis and hair loss due to oxidative stress.
