Introduction

Nikka Chemical Co., through its Hair Science Research Laboratory located in Fukui, Japan, has made a groundbreaking discovery in the field of scalp care. This research centers on the alleviation of scalp itchiness by targeting the environmental factors that trigger the release of Nerve Growth Factor (NGF), a key player in the sensation of itch. Their findings indicate that a mixture derived from mekabu (seaweed), hijiki (another type of seaweed), and natto (fermented soybeans) exhibits potent effects in suppressing scalp itchiness. This development not only holds promise for improving scalp health but also contributes to the wellness of hair itself.

Key Highlights of the Research

• - The team focused on how environmental stimuli can promote the expression of NGF in the epidermis, leading to an increase in itch perception.
• - Their investigations aimed to discover components that could effectively suppress NGF levels and the resultant itchiness.
• - The findings confirmed that the combination of mekabu, hijiki, and natto extracts significantly reduced NGF expression, thereby alleviating itch on the scalp.

Background of the Study

Itchiness is a distinctive sensation localized primarily to the skin and mucous membranes, often described as an unpleasant feeling associated with the urge to scratch. Scalp itch is a common complaint across various age groups and genders, often leading to more severe issues such as hair loss and a decrease in hair vitality. The adverse scratching behavior prompted by itch can lead to secondary complications, including skin dryness and weakened barrier functions, resulting in an unending cycle of itchiness. Understanding the underlying mechanisms and developing effective measures to combat this cycle is essential. The current study noticed that increased NGF levels can cause sensory nerve fibers to invade the epidermis, potentially exacerbating itch.

Research Overview

In this research, normal human epidermal keratinocytes were utilized to screen for effective components that suppress NGF expression. The team applied various environmental stimuli, including UV radiation, dryness, and pollen, to induce NGF expression in cells. Their research successfully identified that the mixture of mekabu, hijiki, and natto extracts suppressed NGF levels across all tested environmental factors. To further validate these findings, a scalp essence was developed that combined the three extracts, which demonstrated significant efficacy in reducing scalp itchiness when applied over a specified duration. Additionally, a patent application has been filed for the functional ingredients shown to reduce itch, supporting their upcoming presentation at the 2024 Japan Cosmetic Technologists Conference.

Future Directions

Building on the research outcomes, Nikka Chemical aims to develop a range of scalp care products incorporating these effective blends. Their objective is to provide solutions for the myriad individuals experiencing scalp issues worldwide. By continuing to innovate and improve their products, Nikka Chemical is committed to meeting the evolving needs of consumers.
