Bed Bath and Beyond (and likely other places) sell a suction cup based shower head holder that will hold your shower head nicely. I put one in our shower for my DW. She's just 5' tall and has very long hair that she tries not to wash every day. So she needed a way to lower the shower head enough so that it would always hit her on the top of the head. It's rather the reverse of your problem, but the cure could be the same.
And as others have said, the Oxygenics shower head is very nice.
