Bioderma Node DS+ Shampoo is the formula which offers increased efficacy against severe and persistent dandruff. The typical characteristics of persistent dandruff are thickness, oiliness, yellowish color, stickiness to the scalp, and itching. The dandruff-causing Malassezia yeasts are inhibited in number by the Nodé DS+ formulation. On the surface of the skin, Malassezia is a type of yeast that exists naturally. Scales, itching, and dandruff are brought on by the scalp's overgrowth of sebum, which is encouraged by its excessive secretion. Sebum production is reduced and Malassezia growth is inhibited by the DSactive™ proprietary compound. The biological activity of the DSactive proprietary complex on the cause of scales ensures dual efficacy. Robust kerato-regulating medicines help eliminate and remove severe dandruff. Nodé DS+ Anti dandruff shampoo is enhanced with calming ingredients, provides immediate and long-lasting relief for irritated scalps. The proprietary natural complex from D.A.F. raises the threshold of tolerance for scalps that are sensitized. All BIODERMA products are formulated according to the ecobiology principles, which is at the heart of NAOS' approach to respect the skin's ecosystem and preserve its health in a lasting way.
