S ylvia Ströher is a German heiress whose fortune is derived from her family's sale of the professional hair care company, Wella AG. The company was founded by her great-grandfather in the 19th century. The Ströher family built Wella into a global giant in the hair cosmetics industry, famous for its professional salon products. In 2003, in a landmark deal, the family sold their controlling stake in the publicly traded company to the American consumer goods behemoth, Procter & Gamble, for over $4 billion.

Sylvia, along with her two brothers who have since passed away, inherited her share of the multi-billion dollar proceeds from this sale. She and her husband, Ulrich Ströher, now manage their vast fortune through their family office, making investments in real estate and other businesses. She is also a prominent collector of contemporary art, with a particular focus on German artists. A significant portion of her renowned art collection is on long-term loan to the MKM Museum Küppersmühle in Duisburg, Germany.
