Do you mean zinc pyrithione? It is found in dandruff shampoos like Head and Shoulders.

The active ingredients in dandruff shampoos include selenium, coal tar, salicylic acid, ketoconazole, pyrithium zinc, etc.
It is an anti-dandruff ingredient. As far as I know, it does NOT share any of these pro-anagen qualities with the ketoconazole in Nizoral shampoo.
