Predia is a premium haircare line from Kose, a 75-year-old Japanese beauty innovator. They created this mask for hair that feels dry and lifeless from modern life—hard water, styling tools, and stress. The formula centers on a patented 'Thalasso' complex, inspired by the restorative power of seawater. Kose's chemists sourced deep-sea minerals and marine collagen, then developed a unique 'Spa Treatment' process to infuse them into the hair shaft. Every batch is made in a GMP-certified facility in Japan, following the same strict quality standards as their skincare. It's a top-ranked hair mask in Japan, consistently praised for delivering salon-level hydration without the salon visit.

The Kose Predia Thalasso Hair Mask N - Deep Hydrating Marine Spa Treatment by Kose incorporates a sophisticated blend of marine-derived and conditioning ingredients designed to deeply hydrate and revitalize hair. Key components include seawater and marine minerals, which are central to the 'thalasso' concept, providing essential trace elements that help strengthen hair structure and improve moisture retention. Hydrolyzed collagen is included to enhance elasticity and repair damage by penetrating the hair shaft to fill in gaps and smooth the cuticle. Ceramides are added to reinforce the hair's lipid barrier, locking in moisture and protecting against environmental stressors. Botanical extracts such as algae and seaweed deliver antioxidants and vitamins that nourish the scalp and promote healthy hair growth, while silicones like dimethicone offer immediate slip and shine by coating the hair to reduce frizz and improve manageability. Humectants such as glycerin attract and bind moisture to the hair, ensuring prolonged hydration. This formulation collectively works to restore softness, add luminosity, and improve overall hair health, making it particularly beneficial for dry, damaged, or chemically treated hair seeking intensive repair and hydration.
