Born from Japan's Kose Laboratories, Predia was created to solve the hair and scalp stress caused by modern life—hard water, pollution, and constant styling. Our researchers in Tokyo identified Blue Algae from the Izu Peninsula as a key ingredient for its unique mineral profile, proven to help hair retain moisture against daily damage. This formula is manufactured in a GMP-certified facility, adhering to Japan's strict Pharmaceutical Affairs Law. It's not just a shampoo; it's a concentrated spa treatment, developed with the same precision as skincare. The result is a top-ranked set in Japan's professional haircare category, trusted by salons for delivering visible results where daily routines fall short.

The Kose Predia Blue Algae Spa Shampoo & Mineral Hair Mask Sachet Set features a carefully curated blend of ingredients designed to cleanse, nourish, and revitalize hair. Key components include blue algae extract, which is rich in vitamins, minerals, and antioxidants to hydrate and strengthen hair strands while protecting against environmental damage. Sodium laureth sulfate serves as a gentle cleansing agent to remove impurities without stripping natural oils, ensuring a balanced scalp. Betaine, a natural humectant derived from beets, helps retain moisture and improve hair elasticity, reducing frizz and enhancing shine. Mineral-rich sea water extracts, such as magnesium and calcium, are included to fortify hair structure and promote overall scalp health. Additionally, hydrolyzed collagen and silk protein work synergistically to repair damaged cuticles, smooth the hair surface, and impart a silky, manageable texture. These ingredients collectively aim to deliver deep conditioning, improve hair resilience, and provide a spa-like experience with lasting softness and vibrancy.
