This dry shampoo doesn't work for me

I tried these for a while, because I wanted to train my hair to wash it less, because I really was my hair every day. Unfortunately, this product really didn't work for me. This is a dry shampoo that I had to spray into my hair the night before I went to sleep and then my hair should look fresh the next morning. Unfortunately, I had to wash my hair anyway, because it really didn't do anything for my hair. I really tried for a long time but unfortunately to no avail.
