Nodé P Normalisant, an anti-dandruff shampoo, biologically eliminates dandruff and keeps it from re-appearing. It respects the balance of the scalp by limiting, through the biological action of climbazole, the presence of Malassezia, one of the micro-organisms that cause dandruff. This antimicrobial activity is strengthened by piroctone olamine and is supplemented by the keratolytic action of salicylic acid. It soothes itching and purifies the scalp. Principle of Non Detergence: like all Nodé shampoos, Nodé P Normalisant is formulated with gentle non-stripping cleansing bases to respect the biological balance of the hair and scalp for optimum tolerance.
