Pinky Promise
A hair product or even a visit to the hair salon is not a necessity. We can make do without them.
Hair however is a part of our identity, it plays a part in our mood, it is a way to express yourself. It’s important for many of us that our hair reflects what we feel we are. That is why we don’t use just any old hair products. We want to do our part in promoting responsible production and sustainable consumption. Our long-term development work aims at creating products with a life cycle built on responsible choices that are based on sustainable development.
