Oribe Serene Scalp Densifying Shampoo Recall Highlights Bacterial Contamination Concerns
7/6/2026, 12:31:51 PM
Background: Bacterial Contamination in Personal-Care Products
The Food and Drug Administration (FDA) has identified Pluralibacter gergoviae as a contaminant that can appear in cosmetics. The organism is noted for its resistance to parabens and other preservatives, a factor that contributed to the 2024 recall of nearly one million units of Amika shampoo. The current recall involves a “very small batch” of Oribe’s Serene Scalp Densifying Shampoo, underscoring ongoing challenges in maintaining microbial safety in shelf-stable hair-care formulations.
Affected Products and Lot Identification

Health Risk Assessment
Pluralibacter gergoviae “poses little medical risk” to healthy individuals, according to the FDA. However, the agency notes that people with pre-existing health conditions—particularly those with weakened immune systems—may be more susceptible to infection. The bacteria is classified as an “environmental bacterium” that “almost never” causes illness in healthy people, per a board-certified dermatologist.
Official Statements & Responses
The FDA issued a nationwide warning, advising the public to discontinue use of the identified lots. Kao USA, the Cincinnati-based parent of Oribe, submitted a voluntary recall to the FDA and reiterated the health-risk language. The company instructed customers to stop using the product regardless of health status, to contact the Kao Professional Hair Technical Hotline (800-333-2442) or email oribecomplaints@kao.com for a replacement, and to report any adverse health effects through the same channels.
Expert Commentary
Mona Gohara, MD, a board-certified dermatologist at Yale School of Medicine, explained that while the bacterium can appear in cosmetics, it “almost never” leads to illness in healthy people, reinforcing the FDA’s low-risk assessment for the general population.
Consumer Guidance and Next Steps
- Discontinue use of any shampoo matching the lot information.
- Contact Kao USA via the hotline or email to arrange a replacement.
- Consult a healthcare provider if symptoms develop, especially for immunocompromised individuals.
- Report adverse events to Kao USA using the provided contact methods.
