If it's not a super high end shower head maybe you can disconnect the hose and see whether the head's flow restrictor can be removed with needle nose pliers- there will be some small and large o-rings that may need to be taken out with a sturdy pin, I used and broke a few toothpicks, or a tiny screwdriver, to get a better hold of the culprit.
I was burning through the Aquasource shower hoses from Lowes every 6 to 10 mos, they come with a lifetime warranty, however not every CS manager will do a one time swap, sometimes he'll refer you to the product maker and the hassle isn't worth it. The backpressure woud cause them to leak, and after I realized what was going on, my current hose has now survived for more than 5 yrs. You can do the same with faucet aerators, even removing the o-rings alone makes a noticeable difference.
In this example the hose comes with it preinstalled, looks flat here, you'll probably have a truncated cone:
