The FDA has issued a voluntary recall notice for Oribe Serene Scalp Densifying Shampoo following confirmed bacterial contamination in select production lots. Kao USA, the manufacturer behind the luxury hair care line, initiated the recall after testing identified a live organism capable of causing serious scalp and systemic infections in vulnerable users.
Two bottle sizes are affected by this recall. The 8.5 fl oz bottle carries UPC 840035231242 and lot code YR010556. The larger 33.8 fl oz bottle carries UPC 840035231273 and is associated with two lot codes: YR010566 and YR010576. All three lots were manufactured between February 21 and February 26, 2026. The lot code is printed in black ink along the bottom rim of each bottle. Consumers should check this location before using any Oribe Serene Scalp Densifying Shampoo currently in their possession, as unaffected bottles from different lots remain safe to use. Those who purchased the product during early 2026 are at the highest risk of holding a contaminated unit and should verify immediately. As a broader consumer safety reference, FDA classifies six hand soap products across 15 states over bacterial contamination risk covers how to interpret FDA product recall classifications.
While Pluralibacter gergoviae rarely infects healthy skin, it poses severe risks of folliculitis, eye infections, and systemic illness for individuals with scalp irritations, compromised immunity, or post-surgical incisions. If the bottom of your Oribe bottle displays code YR010556, YR010566, or YR010576, stop using it immediately. Seal the container and contact Kao USA for a full refund or safe replacement.
Pluralibacter gergoviae is a gram-negative bacterium found naturally in soil and some cosmetic formulations. What makes it particularly concerning in personal care products is its documented resistance to parabens — the class of preservatives most commonly used in shampoos and conditioners to prevent microbial growth. When paraben-based preservation fails against this organism, contamination can persist through the product’s shelf life without visible signs of spoilage. For people using the Serene Scalp line specifically — a product marketed toward those experiencing hair thinning or scalp sensitivity — the risk profile is elevated. Thinning hair is frequently associated with scalp inflammation, increased follicular vulnerability, and minor micro-abrasions from more frequent washing or topical treatment use. Those conditions create entry points for opportunistic pathogens like Pluralibacter gergoviae that would otherwise be blocked by intact skin. Anyone managing an underlying scalp condition while using this product is encouraged to consult a dermatologist.

Healthy individuals rarely develop serious complications, but contaminated shampoo can trigger itchy scalp rashes, folliculitis, or eye irritation. For individuals with open scalp sores or weakened immune systems, the bacterium can enter broken skin and lead to difficult-to-treat secondary bacterial infections requiring targeted antibiotics.
