They do not all leak. The problem may be that your faucet is simply wearing out and is due to be replaced in total. Try putting some plumbers grease on the cartridge and the chamber.....not too much..........that may do the trick for u.

The valves are leaking. It's not the shower head itself. Sometimes shower faucets require special tools to service the valves. If you have thought about new shower valves, now would be a good time to replace. Repair may be half the cost of installation of new. In other words, plumber's time to repair or replace is about the same. Get several quotes. TV show This Old House had one on a replacement. It may be available online. Home Depot or Lowes or Ace Hardware may be able to help, Or similar Hardware outlet in your area.
When shower faucet apart make sure hot is getting 2 & coming out faucet ***. did you turn off stop integral w/ faucet or outgoing shut off valve on water heater.. May have rust or lime in small orifice leading to faucet ***. does your balancer/ piston move freely..good luck..
I just spent a week wrestling with a similar problem, and I'm posting in an attempt to save someone else an ulcer. Using a Colony single-handle valve, the temperature got so we couldn't control it. Either all hot or all cold. I called A.S. and they sent a new pressure balancing cartridge and new valve cartridge. Replaced both and then there was no water at all coming out of the shower head. Tried every possible combination of old and new parts, flushed pipes, etc. Finally took the shower head off and found it completely clogged with debris. It was a mix of sediment and the white grease that was in the new cartridges, which must have been displaced when I started messing with it. And it clogged it all at once (no flow problems before all of this). Works fine now!
Remove the retaining clip holding cartridge in - you can use a pair of long nose piers or a small screwdriver
Grab the cartridge with a pair of pliers and pull straight out. It may require a little force - there are O-rings around the cartridge to keep it from leaking.
Check the cartridge bore (the hole where the cartridge was removed)
Clean any debris or scale - lime away or CLR will work
Apply a little bit of soap around the new cartridge to help it slide in easier. Push it all the way in and make sure it is seated. Re-install the clip (you should have received a new clip with the replacement cartridge)
You may want to disassymble the faucet again and check for any debris that could have gotten into the faucet when you were changing the cartridge. Also remove the seats at the back of the housing and reexamine for bad seals. Sometimes it takes a second install for it to stop. Something isn't seating properly plus, it could be a bad new cartridge.
You may have debris caught in the cartridge. I'm not sure which faucet you have but if it utilizes a ball, there is a retaining ring that is either grey or white that you have to tighten. If not, I would recommend contacting American Standard. You might have a bad cartridge or missed replacing another part. Sometimes they have small round washers at the back of the housing that need to be replaced as well.
this problem happens quite regularly as the valve will reduce the pressure but sometimes it will reduce too much, you can adjust it up, but you havent mentioned which type of shower valve it serves?
as the shower may not be suitable for the plumbing supplies it connects too , & how they are installed?
i am thinking its from the cold water main & that the valve requires storage feed instead of incoming water main supply? possibly thats why you installed a reducing valve??
