Brand new, unopened The world's first hair care series that doesn't contain a single drop of water * Formulation does not contain water as a raw material. Ultimate hair care that doesn't contain a single drop of water. Instead of water, Collagen extract is the main ingredient. General hair & body care products are made with more than half water. This is because using mostly water for the ingredients can keep the cost down. However, because we want to deliver the highest quality products, we use "collagen extract" instead of water, maximizing the moisturizing power. We provide an unprecedented beauty experience that can only be achieved by not compromising and not using a single drop of water. That is the Kuu Aqua free series. Born from the luxury head spa salon Kuu Kuu Aqua free series Rimveil made from 100% natural Mozuku seaweed from the Kingdom of Tonga As a common ingredient of the Kuu Aqua free series, we use "Rimveil," a component of natural Mozuku seaweed. Protective effects to protect hair and skin, damage repair effects, and high moisturizing effects can be expected. Fundamental care creates true beauty The most common ingredient in general hair care products is water (about 70-90%). In the case of Kuu Aqua free series, we have replaced all of this water with the beauty ingredient "collagen extract." As a result, it nourishes and moisturizes the scalp and hair, creating "true beauty" from within the hair. Fundamentally improving hair and skin leads to long-lasting beauty. With the Kuu Aqua free series, you can get fundamental hair care like a head spa salon in your home. Why not restore your natural beauty at home?
