Shampoo Recall: Hidden Bacteria Found in Popular Hair Product

Kao USA Inc. has initiated a voluntary recall of specific batches of Oribe Serene Scalp Densifying Shampoo. The recall, announced on July 1, 2026, followed the detection of Pluralibacter gergoviae bacteria in the product. These affected lots were produced between February 21 and February 26, 2026.

The shampoo was distributed across the United States and Canada, with California consumers among those who may have purchased the contaminated item. While Pluralibacter gergoviae is generally not harmful to healthy individuals, it can lead to infections in those with compromised immune systems or certain pre-existing health conditions.

Consumers possessing the recalled shampoo are instructed to discontinue its use immediately and dispose of the product. For inquiries or to report adverse reactions, customers can reach out to the Kao Professional Hair Technical Hotline or via email. Retailers are cooperating to remove the affected products from shelves.

Cosmetic product recalls, though less common than food or drug recalls, can occur due to bacterial contamination. Such contamination is concerning for personal care items that contact the body directly, posing a greater risk to vulnerable populations like older adults, young children, and the immunocompromised.
