What is Kind To Biome?
Kind to Biome is an official accreditation confirming our shampoos keep your scalp and hair healthy as they don't interfere with the skin microbiome. Your microbiome is the collection of microorganisms which can get affected by hair products leading to inflammation or sensitivity, and conditions such dandruff, itching or flaking. This can inhibit new hair regrowth and lead to dryness. If you suffer from these, you may have an out of balance scalp microbiome.
