Swiss O-Par Silver Shampoo

Swiss O-Par is a well-established hair care brand originally founded in Germany. The brand was introduced by Rufin Cosmetic GmbH, a family-owned company established by Otto Rumpfkeil in 1960. While the brand name suggests a Swiss connection, it is firmly rooted in German manufacturing and entrepreneurship. Initially developed as a professional line for hair salons, it transitioned into the retail market in the 1980s and 1990s.

The product is manufactured in Germany, specifically at the Rufin Cosmetic facilities located in Wedemark, near Hanover. Ownership has remained within the founding family through Rufin Cosmetic GmbH, which continues to manage the brand's production and distribution globally as of 2026. The Silver Shampoo is specifically formulated to neutralize yellow tones in blonde or gray hair, maintaining the brand's focus on specialized hair solutions.
