Hair Detangling Evaluation Method Using Section Detangling Rate Open
This study was conducted to objectively evaluate the degree of detangling needed to develop the effectiveness of cosmetic hair ingredients to prevent hair tangles. To evaluate the degree of hair tangling, the frictional force applied when …

The Anti-Flyaway/Frizz Effect by Inducing the α-Helical Structure Transition of Hair Open
In order to reduce chronic hair flyaways/frizz, both reducing and oxidizing agents have to be used, leaving aside the hair damage issues. This study presents changes in hair morphology caused by treatment with a shampoo containing only red…

Biomimetics Through Bioconjugation of 16- Methylheptadecanoic Acid to Damaged Hair for Hair Barrier Recovery Open
The primary component of the lipid barrier on human hair, which is essential for defense against aging and environmental stresses, is 18-methyleicosanoic acid (18-MEA), which provides hydrophobic properties and protective benefits. Since 1…

Hair Pores Caused by Surfactants via the Cell Membrane Complex and a Prevention Strategy through the Use of Cuticle Sealing Open
In this study, we discovered that washing hair with surfactants causes a decrease in the internal density of hair, and we propose a cuticle-sealing strategy to inhibit this phenomenon. This phenomenon was revealed based on optical analyses…

Ultrafast Dynamics and Anionic Active States of the Flavin Cofactor in Cryptochrome and Photolyase Open
We report here our systematic studies of the dynamics of four redox states of the flavin cofactor in both photolyases and insect Type 1 cryptochromes. With femtosecond resolution, we observed ultrafast photoreduction of oxidized state (FAD…

Comparative Photochemistry of Animal Type 1 and Type 4 Cryptochromes Open
Cryptochromes (CRYs) are blue-light photoreceptors with known or presumed functions in light-dependent and light-independent gene regulation in plants and animals. Although the photochemistry of plant CRYs has been studied in some detail, …

Dual Case Reports for Lipid Loss from Human Hair Open
This study aims to understand the mechanism of lipid loss from the hair upon contact with surfactants. We herein proposes that the process of lipid loss can be categorized into two mechanisms. In the first mechanism, the lipids inside the …
