The best flea shampoo in my opinion is the product put out by Sulfodene called Scratchex Flea and Tick Shampoo as it has no heavy perfume odor, it works well to remove fleas and seems to have a residual effect from the permethrin insecticide.
Better than a flea shampoo though is using a product such as Frontline.
