Abstract

<p>Recently many people have begun choosing their original wavy hair instead of straightening their hair. However, they have to put a lot of effort into hair styling as curls are difficult to control. One of the important requirements for beautiful wavy hair is well-defined curl alignment as curls with lustrous and frizz-less appearance are often preferred. Therefore, new approaches to make well-aligned curls are valuable. We focused on the curvature of single hair fibers in curl bundles. The result of curvature measurement showed that well-aligned wavy hair has a narrow curvature variation. We have found that Sodium 2-naphthalene sulfonate (SNS) can decrease curvature variation. By applying SNS to wavy hair, each fiber spontaneously harmonized in curls, which result in well-aligned wavy hair with luster and less frizz. The relationship between curvature and hair structure was then investigated and it was found that the more bilateral distribution of two types of cortical cell was seen in the higher curvature part. A mechanical model was proposed to explain how SNS straightens hair and decreases curvature variation reflecting the distribution of two types of cortical cell. This technology would be a breakthrough which releases consumers from daily stress due to styling and making their original hair shape more attractive.</p>
