Product Overview

"GRAND CARE YS" is a scalp care serum formulated with Eriodictyon Angustifolium Leaf/Stem Extract (moisturizing ingredient) derived from Yerba Santa. By incorporating it into your daily scalp care routine twice a day, morning and night, after waking up or after bathing, it promotes a healthy scalp, which is the foundation of your hair.

The product will be available in a 95mL bottle and a 190mL refill for continued use.

Development Background

The condition of hair and scalp gradually changes with age, lifestyle, and daily hair styling. For those who want to continue enjoying their hair styling, maintaining the condition of their scalp and hair daily is an important habit that supports the finish at the hair salon and its subsequent beauty.

On the other hand, hair salons are required to propose home care that customers can continue easily, while also catering to the changing needs of each individual customer's hair.

"GRAND CARE YS" was planned as a scalp care serum to meet these needs of both customers and hairdressers, by keeping the scalp, the foundation, healthy with daily care.

Starting with sales at hair salons, it will be offered as a product that can be easily incorporated into daily care, with proposals on how to use it and support for continued use by hairdressers.

Product Features

Scalp Care Serum to Keep the Foundation Scalp Healthy

"GRAND CARE YS" is a scalp care serum aimed at keeping the scalp and hair, which form the foundation, healthy through daily hair care. It is proposed as a new morning and night routine to enjoy hair styling for longer.

Formulated with Moisturizing Ingredients Derived from Yerba Santa

Yerba Santa is called "sacred herb" in Spanish. Among them, we have incorporated Eriodictyon Angustifolium Leaf/Stem Extract, a moisturizing ingredient derived from the Eriodictyon Angustifolium species. Lavender oil has been added to the natural scent of Yerba Santa to create a fragrance that is easy to use every day.

Easy-to-Continue Usage Design: Twice a Day, Morning and Night

The intended use is to apply about 20 pushes to the entire scalp after waking up and after bathing, and gently massage with fingers. To make it easy to incorporate into daily care, in addition to the 95mL bottle, a 190mL refill is also available for continued use.
