In order not to have to do these strange manipulations with a cap, you need to buy a cap of your own size and good quality. I usually order mine at .https://headwearhut.com/collections/custom-5-panel-hats and they fit perfectly on my head . I wash them quite often because I work a lot in the dust and of course the cap gets dirty. But immediately after washing, I put it on and it looks and falls on my head as before. There was no such thing that it was deformed. Therefore, in order not to bother, just buy a normal cap

I also love the wet shaving.
