I'm guessing I'm not totally alone when I say my head shape doesn't easily fit into the standard oval hat block shape used for most hats.

I have a few of those relatively inexpensive hat stretchers (Hat-jacks) that they sell at just about every good hat store. The first time I used one I was really happy to have found a tool that could help me relieve the front-to-back pressure I get with nearly all hats.

I initially shaped my hat-jacks in a way that I thought was more closely aligned with the actual shape of my head. After using them on multiple hats for more than a year, I was seeing some shortcomings with the design.
