"Looking in the mirror has become a little depressing." - Gray hair and changing volume increase with age. However, these changes are delicate and difficult to talk about with others.

The home scalp care "Re.Age NMN® (Ri-Age NMN) Series," developed by Regenerative Hair Salon® Rine (Operated by: Regenerative Hair Salon Rine Japan Co., Ltd. / Saitama City, Saitama Prefecture, Representative Director: Mari Kimuwada), surpassed a cumulative total of 10,000 units sold (total of 4 products) in April 2026. Originally salon-exclusive products provided by Regenerative Hair Stylists® began general sales in July 2025. Focusing on "fluctuations in scalp environment," the concept of nurturing from the scalp, the foundation of hair, continues to be chosen by adult women concerned about their hair.

"Regenerative Hair Stylist®," "Regenerative Hair Salon®," and "Re.Age NMN®" are registered trademarks of Rine Japan.

◆ Responding to "Hair Concerns That Can't Be Told to Anyone" from the "Foundation"

Gray hair, volume, hairline—hair concerns become more familiar with age. In fact, 81.0% of women aged 40-80 have hair concerns, with the top concern being "gray hair" (57.6%), followed by "lack of firmness/body in hair" (22.3%), and "low hair volume" (20.2%), reflecting changes unique to the adult generation (Source: "Survey on Awareness and Actual Conditions of Fashion and Beauty Among Women Aged 40-80 in 2024" by Halmek Institute of Living Well).

While we don't want to dismiss it as "just because of age," delicate concerns are hard to talk about, and we tend to give up. However, the changes that appear in our hair may not be solely due to the unavoidable aging process. The condition of the hair is deeply related to the scalp environment, which is the "foundation," rather than the surface.

Regarding this change, developer Kimuwada states, "Fluctuations in the scalp environment are deeply involved in the background of hair concerns. Repeated coloring treatments, disruption of lifestyle rhythms, aging, nutritional deficiencies, and stress—these combine to burden the scalp, making it prone to affecting the hair's appearance" (Mari Kimuwada, Representative of Regenerative Hair Salon® Rine).

◆ Make the Salon's "Scalp Conditioning Process" a Daily Habit

The "Re.Age NMN® Series" was born from this concept. The "scalp conditioning process" that Regenerative Hair Salon® Rine has provided in salons has been translated into an easy-to-continue daily home care routine. With a 4-step process of NMN Shampoo, NMN Treatment, NMN Scalp Essence, and NMN Serum, it resets the scalp environment by removing excess sebum and dirt, and cares for dryness. It delivers moisture to the scalp and hair, adding firmness and shine. With a design that can be continued without strain, the scalp condition is gradually improved with daily care, leading to shiny hair and a fluffy, three-dimensional impression. Feedback from those who have continued includes, "I'm so happy with the changes in just 3 months of online support" (50s, Female) and "I'm no longer bothered by gray hair, and looking in the mirror is truly enjoyable" (60s, Female).

◆ Regenerative Hair Stylists® Who Support Your Hair, Nationwide

What supports the spread of this series is not just the products. It is the existence of Regenerative Hair Stylists®, specialists who support hair and scalp concerns, capable of multi-faceted approaches to hair problems such as thinning hair, fine hair, and gray hair, which could not be covered by conventional treatments.

With the desire to "support each individual with hair concerns, not just salon clients, regardless of time or place," the "RBA Academy" to train Regenerative Hair Stylists® was opened (2024). Through an approximately 6-month program, participants acquire knowledge to address hair concerns online, covering not only hair and scalp but also diet, lifestyle habits, and overall condition.

On June 30, 2026, the third cohort of students completed their program, and new Regenerative Hair Stylists® who share this vision have embarked on their careers across the country. Those who purchase the products can also consult with a Regenerative Hair Stylist® online about their hair concerns. As connections with experts become more accessible, the circle of support for individual concerns is steadily expanding. The milestone of 10,000 units is proof that this sentiment is beginning to be truly felt.

◆ Developer Mari Kimuwada's Vision

"I've heard many times people say, 'I'm too old,' and give up on their hair. But if we turn our attention to the scalp, the 'foundation,' before the surface of the hair, hair can change at any age. We aim to transform hair advice, which has often relied on intuition, into 'expert proposals' based on evidence, such as lifestyle habits. The number 10,000 is a testament to the agreement with and trust in that approach. We will continue to spread our approach to thinning hair, fine hair, and gray hair nationwide through both products and human resource development" (Representative Director, Mari Kimuwada).
