Enhanced Rishiri Color Treatment

The renowned Rishiri Color Treatment, a beloved product from Puru Co., has been revamped and is set to launch with a new look on October 1, 2026. Known for its powerful dyeing effects and hair repair benefits, this treatment has surpassed 37 million units sold and is being relaunched with an exciting new color: Marron Brown. The treatment is now available in a total of five stunning shades.

Key Features

The newly formulated Rishiri Color Treatment not only offers vibrant hues but also enhances the overall health of your hair. It promises:

• - Instant Dyeing: Achieves a vivid color from the first application.
• - Hair Repair: Provides nourishing qualities to repair and protect each strand, resulting in smoother, silkier hair.
• - Five Color Options: Now including the natural and warm Marron Brown, alongside existing shades that complement black hair beautifully.

Background of the Product

The Rishiri Hair Color series was born from the founder's personal struggles with sensitive skin, aiming to offer a hair color solution that women with delicate scalps can safely use. Over the past 20 years, the brand has focused on gentle formulations, and the new Rishiri Color Treatment adheres to this philosophy by leveraging the natural benefits of Rishiri Kombu.

User Feedback and Innovations

A survey conducted among loyal customers revealed a resounding appreciation for the treatment, but it also highlighted a demand for improved dyeing effectiveness and ease of use. With this feedback in mind, the new formulation achieves a 106% improvement in dyeing power, thanks to a proprietary Color Boost & Delivery System that enhances how the dye interacts with hair. The result is a richer, more vibrant color, maintained over time.

Proprietary Ingredients

The reformulated treatment now boasts:

• - 30x Concentrated Natural Rishiri Kombu Extract: A significant boost that provides about 30 times the concentration of beneficial ingredients compared to previous formulations.
• - World First Kombu Fermentation Liquid: Created from fermenting Rishiri Kombu with lactic acid bacteria, this unique ingredient offers profound hydration.
• - Hair Repair Ingredients: This includes an advanced gloss shield component to form a protective layer that preserves color and enhances shine while deeply conditioning the hair.

Ease of Use and Inclusivity

The treatment is designed for user-friendly application, whether applied on damp or dry hair. It features an improved creamy texture that allows for a smooth and effortless application, minimizing mess and ensuring the dye penetrates effectively.
