The story behind Hiroko skin and hair care products

Welcome to the captivating world of HiRoko Science, where cutting-edge skincare meets a legacy of transformative medical breakthroughs. Our journey begins with Dr. Hiroko Yanaga, a trailblazer in the field of regenerative medicine and a pioneer in epidermal cell research. In 1985, she, alongside Dr. Kumagai and a dedicated team, achieved a groundbreaking milestone by successfully employing autologous cultured epidermal cell transplantation to treat children with extensive burns, marking the first of its kind in Japan.

Dr. Yanaga's unwavering commitment led her to further heights, including a prestigious research opportunity under Dr. Howard Green at Harvard University. Under his mentorship, she mastered the revolutionary Green Method for epidermal cell culture, solidifying her status as a luminary in the field. Dr. Green is considered by many to be the father of regenerative medicine; his mantra, “research should never be limited to a laboratory; research gains life only when applied to help patients" has greatly influenced Dr. Yanaga's work.

The culmination of over 30 years of relentless research and dedication is the HiRoko Science series—a range of skincare products designed to activate and rejuvenate epidermal cells. These formulations address a spectrum of conditions, from dry skin to acne, harnessing the power of Dr. Yanaga's extensive expertise in cultivating healthy skin.

Beyond skincare, Dr. Yanaga's impact extends to breast reconstruction, where her work has established her as one of national leaders for over three decades. The holistic approach to patient well-being is evident in the development of HiRoko Scalp Shampoo, created to restore vitality and luster to hair, particularly for those navigating the challenges of chemotherapy and beyond.

After breast reconstruction, patients often expressed concerns about hair loss following chemotherapy, and even when hair grew back, it was thin and lacked its previous luster. Dr. Yanaga decided to develop a scalp shampoo containing all the nutrients needed to restore the hair's natural vitality and shine.

HiRoko Scalp Shampoo was developed to help patients struggling with hair loss due to chemotherapy. However, it has also shown similar effects for individuals dealing with age-related hair thinning, alopecia areata, damaged hair from excessive dyeing, and male pattern baldness.

The HiRoko Science story is an ongoing narrative, rooted in the belief that persistence is power. As we continue to pioneer advancements and refine our products, our mission remains clear: to empower individuals worldwide to look and feel their best, enhancing their quality of life. Explore the intersection of science and beauty with HiRoko Science—the evolution of skincare and the promise of a radiant future.

I believe that as we grow older, looking beautiful will help us enjoy more fulfilling lifestyles, it is in human nature to try to look beautiful even as we age.

We look our best when we are the healthiest. If we provide our body with the right nutrients to stay healthy beauty will follow. Our food defines our body and it can also be its best medicine. Eating well, exercising, laughing will lead us to health. Proper care and supplying the skin with the nutrients it needs to stay healthy will lead us to have beautiful skin.
