The ingredients to make dry shampoo are very easy. It’s really cornstarch and baking soda. The cornstarch helps absorb oil and the baking soda deodorizes. This is all you need:

1 cup of cornstarch
1 cup of baking soda
essential oil (optional)
an empty spice container

Add the baking soda and cornstarch to the plastic spice container. Add a few drops of essential oils to the mixture. You can use whatever fragrance you like. The essential oil is solely used to add a lovely smell. Don’t go overboard; essential oils are strong and a little goes a long way. Replace the lid and give the bottle a gentle shake to mix.
Sprinkle a generous amount of the shampoo on your dog’s coat. Protect the face, specifically the nose and eyes, when sprinkling it on. Rub the dry shampoo into the coat until it reaches the skin. If your dog gets up and shakes a bit, that’s fine. The shaking will help remove the excess powder. Brush your dog thoroughly to get the rest of the shampoo off of the fur. This may take a few minutes. Rub your dog down with a clean towel to get the rest of the shampoo excess off the coat.
You can use the dry shampoo weekly if needed. Just make sure after each application you get as much off their fur as you can. Daily brushings will help keep your dog’s natural oils evenly distributed, making it less likely the dog’s skin with dry out.
