Davis Tearless Shampoo is a soap-free formula with a special combination of ingredients that is gentle on the eyes. Extremely mild, it prevents dryness and irritation by restoring the skin's natural moisture while providing a deep cleansing bath. This pH balanced shampoo rinses reside-free and is easy on the bather's hands as it does not strip the natural oil from the skin. It leaves a light, clean fragrance and is gentle enough for frequent use. Davis Tearless can be used with all spot-on and spray-on insecticide products. A bottle of 12 oz concentrate makes up to 120 ounces of shampoo.
