Selsun Blue shampoo

Selsun Blue is a globally recognized brand specializing in medicated anti-dandruff shampoo solutions. Historically formulation focused on selenium sulfide as an active ingredient, it has become a staple in the personal care industry for treating seborrheic dermatitis and scalp-related concerns.

The brand was originally developed by Abbott Laboratories in the United States during the mid-20th century. Over the decades, the brand's ownership has transitioned through major pharmaceutical and consumer goods entities. While it was once part of the Chattem portfolio, Chattem itself was acquired by Sanofi, leading to Sanofi managing the brand for several years. In 2024 and heading into 2025, the brand moved into the portfolio of Opella, Sanofi's dedicated consumer healthcare business unit.

Manufacturing of Selsun Blue occurs in various regional hubs to satisfy global demand, including facilities in the United States and specialized production lines in Asia. The brand remains a dominant player in the medicated hair care category under the governance of its European parent company.
