Conventional personal care product preservatives can damage or otherwise interfere with the body’s microbiome, so Mother Dirt products are formulated without those ingredients. Now the brand has announced updates to its shampoo that significantly extend its expiration date.  

Mother Dirt is the consumer products division of the biotech firm AOBiome, a company dedicated to bettering human health by leveraging the benefits of ammonia-oxidizing bacteria. Mother Dirt has been selling a small selection of personal care products that replenish and support the human microbiome since 2014.

And still today this remains the brand’s top priority: “Beyond any singular update, we're most excited to be pioneering a new way to develop products with the skin's microbiome at the forefront,”​ Jasmina Aganovic, president of Mother Dirt, says in a press release about the updated shampoo.

She goes on to explain that Mother Dirt’s “patent-pending development process ensures that each ingredient and formula are tested against the most sensitive beneficial members of this microbial ecosystem, something no one else in the industry is currently doing.”

New and improved

Now Biome-Friendly Shampoo from Mother Dirt has an expiration date of 6 months, that’s 3 times longer than the shampoo was good for use previously. “The nature of preservative-free formulation requires all Mother Dirt products to come with an expiration date that ensures stability and freshness,” ​according to the brand’s press release. “These expiration periods span months, not years, an important distinction relative to an entire industry that formulates with preservatives that are inherently anti-microbial in purpose and activity.”

The product packaging is new too. Rather than in an air-tight package, Biome-Friendly Shampoo now comes in a squeezable container. The new bottle uses much less material, nearly 50% less plastic than the old packaging. This change supports Mother Dirt’s efforts to limit the environmental impact of consumers' personal care routines.

Mother Dirt doesn’t expressly say the shampoo formula has changed or that testing found the opened shampoo more stable than initially thought. But the press release does emphasize that “The Biome-Friendly Shampoo is a color-safe formula with only 6 plant-based ingredients that enables users to extend the time between shampoos.”
