The FDA told people to throw away Oribe shampoo after checks detected bacteria in the batches.
The agency noted any consumer who uses the product might develop an infection.
The bad batches were found in California stores solely.
The FDA said to pick up the bottle and send it back for a full refund.
Groups that watch products for buyers urged to check shelves at home now.
The recall came after TV stations in Arizona and elsewhere aired warnings about the shampoo today.
