Symbiose: Cellular Anti-Dandruff Haircare

Long-lasting anti-dandruff efficacy with luxurious care

Powered by a unique synergy of three active ingredients, Symbiose reinvents anti-dandruff care at a cellular level to prevent dandruff from reappearing while replenishing the hair fiber’s moisture for ultimate hair health.

How Does Symbiose Work?

Contrary to common belief, dandruff is not just a hygiene issue caused by bacteria. It actually results from a disruption in cellular renewal.

Due to the rapid overgrowth of Malassezia, the rate of cellular renewal becomes twice as fast as in a healthy scalp. Dead cells accumulate, making dandruff visible.

Symbiose combines three powerful active ingredients that work with the scalp to regulate buildup and cellular renewal speed:

• Salicylic Acid – A key skincare ingredient that exfoliates dead cells and removes dandruff.

• Bifidus – Helps balance the scalp microbiome.

• Piroctone Olamine – Targets the bacteria responsible for dandruff, slowing down cellular renewal to prevent flaking.
