What is your experience with dry shampoo?

I wash and condition my hair every morning which I know isn’t recommended but if I don’t I find my hair gets greasy and lifeless very quickly. I am very proud of my hair, I get a lot of compliments on how good it always looks and would be very uncomfortable leaving my house with greasy hair so I recently bought some dry shampoo (Aussie) to see if this is a good substitute to washing every day. Is dry shampoo something you use on your hair and do you have any tips on how to use it to make your hair look awesome? The one I have bought promises volume as I love having big hair!!!
