If that’s the only way you’re going to be able to shampoo your cat, it’s better than nothing.
HERE’S THE DEAL . . .
Dry shampoo absorbs oil into a substance that can be brushed or blow-dried out. Cats produce oil. There will always be oil on their skin. The oil makes fur look dirty.
“Only hydrophobic soils, like natural oils and oil-based styling products, are absorbed by the dry shampoo. Dry shampoo will not remove actual dirt, skin flakes, and other chemicals that can make hair look and feel greasy . . . “
Note: hydrophobic means not dissolvable or wettable by or in water.
Some formulators add ingredients to shampoo to soften the fur or make it shinier.
So no, dry shampoo is not a scam. It’s nowhere near as effective as wet shampoo, but it is better than nothing.
