Kao USA is voluntarily recalling select lots of Oribe Serene Scalp Densifying Shampoo in the U.S. and Canada after detecting Pluralibacter gergoviae. The recall is limited to specific bottle sizes and lot codes manufactured in late February 2026, and consumers are being told to stop using affected products and seek replacements.

Kao USA is voluntarily recalling specific lots of Oribe Serene Scalp Densifying Shampoo in the U.S. and Canada after detecting Pluralibacter gergoviae, a bacterium linked to cosmetic contamination.

The company said the risk to healthy consumers is low, but the product may pose a greater concern for people with weakened immune systems. Retail and salon partners have been asked to remove affected stock from sale and use.

What products are affected

The recall is limited to 8.5 oz bottles with lot code YR010556 and 33.8 oz bottles with lot codes YR010566 and YR010576.

Kao said the affected bottles were manufactured between February 21 and February 26, 2026. The lot code is printed in black on the bottom of the bottle.

What consumers should do

Kao is telling consumers to stop using the shampoo if it matches the recalled lot codes and to contact the company for a replacement or to report any issues.

The company said it is working with the U.S. Food and Drug Administration and that its investigation into the contamination is ongoing.

Why the recall matters

Pluralibacter gergoviae is a bacterium that can appear in cosmetic products and is treated as a higher-risk issue for people with compromised immune systems.

The recall appears to be narrow and lot-specific, but it affects both retail and salon inventory in two countries, making it important for consumers and professional users to check bottle labels closely.
