Ideally my shower cap doesn't get wet either because if the seam of it against my skin gets too wet then the water might get into the cap and the things the humidity will do to the hair...
So on goes the cap, and then begins the calisthenics.
To be fair I usually need to do this because I just finished at the gym so light stretching while in the shower is not the worst idea anybody ever had anyway.
Its there, sometimes. Sometimes there is no shower caps, sometimes it appear after I have entered the shower. Sometimes it is because it is already on my head. Sometimes my cat found a new bed, so no shower caps
Sometimes there is a shower caps, a lot of times there is none
