System Professional Purify Mask 400ml

Created under dermatological supervision and advanced testing, the Purify line offers gentle and effective treatments to restore your scalp environment without throwing off your delicate pH balance. Nourishing and intensely moisturising, the weekly mask treatment works to actively combat all known causes of dandruff with three soothing star ingredients. A powerful antibacterial, antimicrobial and antifungal ingredient, Zinc Pyrithione is a great inhibitor of yeast growth, the main contributing factor in dandruff formation. Witch Hazel extract helps reduce inflammation, while Allantoin calms and comforts irritation. With regular use, hair feels intensely conditioned and flake-free. Dermatologist-developed and tested.
