P&G is seeking removal of the product from store shelves and monetary compensation for damages. P&G this year has filed five similar package-design infringement suits against other haircare companies.
Suits against Dep Corp. and Benjamin Ansehl were settled in P&G's favor this spring; both agreed to change their package designs to distinguish them from the Head & Shoulders brand.
Two judgments were entered against companies owned by L.D. Hardas, preventing them from further infringing the Head & Shoulders and Pert Plus brands.
But P&G has filed an application for a contempt order against Hardas for failing to comply.
A suit against Russ Kalvin Hair Care Co. is still pending.
