Unexpectedly, the inventors found that microorganisms of the Lactobacillus sp. and/or Bifidobacterium sp. genus reduced dandruff conditions by acting on the hydration and barrier functions of the scalp. They also optimized the assimilation of nutrients provided in one's diet, at the level of intestinal mucosa, and assisted in cell metabolism and various functional and structural mechanisms in the skin.

These actions, according to the inventors, reinforce the barrier functions of the skin and reduce inflammatory conditions while preserving a balanced ecoflora. The scalp, in turn, is less irritated and fragile, and more hydrated. Furthermore, this treatment is reported to act more quickly and intensely than the isolated use of anti-dandruff agents.
