First, remove the shower head and test the valve. If you have plenty of water at the shower with the head removed, then the problem is a clogged shower head. Clean it or replace it.
What the hell...just replace it. You deserve it. Go buy one of those cool shower massage heads to replace it.
If you discover you have poor flow at the head with the shower head removed, then you have a blockage in your valve.
So you buy a 1/2 (female pipe thread) x Hose Thread adapter. Put that on the arm for your shower head. Turn off the water to the house. Borrow a neighbors hose and run it through a window and connect it to the shower head (hose thread adapter). Now take the hose off your washer box and drop the hose into the drain hole. Now turn on the water.
The water from your neighbor will allow you to backflush that valve. The debris will backflush and wash out through your laundry hose on down the drain.
If that doesn't work, then yes, you probably need to replace the entire valve.
(I'm assuming your already taken the cartridge apart and cleaned it)

Is your tub spout still running alot of water through it when you use the shower? If so replace spout, if three valve, replace center diverter. If that is all ok, Then yes take off shower head and see if you have the pressure, if so install new shower head and or clean. If not head, then screw on .5 x hose adpt. to the shower arm, you will have to have one washer hose to connect to your outside faucet then to your garden hose which will connect to the shower arm. Leave faucet hot and cold water off, turn on outside faucet all the way, this will let the water go through the valve and out the spout. If this does not work replace faucet.
To increase shower head pressure if it is low, you can try cleaning the shower head, checking for any clogs, adjusting the water pressure valve, or installing a new shower head with higher pressure capabilities.
Aerator in shower head is plugged up. Unscrew head, clean it out, and replace. Make sure you have teflon tape on hand for the treads on the shower arm when putting the head back on.
To increase water pressure in your shower head for a high-pressure experience, you can try cleaning the shower head, removing any blockages, checking the water flow restrictor, and ensuring the water supply valve is fully open. If these steps don't work, you may need to consider installing a new shower head designed for high pressure.
May be build up in the valve itself or the shower head.
Your water pressure is low. Consequently, when cold water is diverted to another application such as a toilet or a sink, the amount of cold water available at the shower mixing valve decreases as the low pressure is unable to keep up with the shower's demand. This causes a hotter mixture at the shower head. The solution is to either improve the cold water supply to the shower or to replace the shower control valve with a temperature compensating type. Pressure balancing is the cheapest and simply changes the shower temperature according to the pressure in the cold and hot water lines. When the toilet or sink is used, reduced pressure to the shower valve is detected and the valve reduces the hot water pressure, thereby maintaining the temperature. The more sophisticated approach is a thermostatic shower control valve. These are significantly more expensive, but will not reduce the pressure at the shower head (a drawback of the pressure balancing valve). The thermostatic valve would be required when one shower control valve is operating several shower heads. Moen, Kohler and Delta all make both types of control valves. They can be readily obtained from a local plumbing supply house.
Open up the actual shower head and remove the factory fitted restrictor.
Yes, you can install a tee in the riser. The pressure loss will be minimal since both shower heads will have a flow restrictor unless you remove them. If you remove them, you probably wont notice any difference. If you do notice a difference, put the flow restrictor back in the closest shower head to the shower valve.
To increase the pressure in your shower head, you can try cleaning the shower head to remove any mineral deposits that may be blocking the flow of water. You can also check the water pressure in your home and adjust it if necessary. Additionally, installing a high-pressure shower head or a shower head with a smaller nozzle size can help increase the pressure.

The force of the spray from a shower head has more to do with the water pressure delivered by your plumbing. Some shower heads do have a valve that allows pressure to build in the shower head, thus delivering a more powerful spray, but sufficient water pressure would be necessary from the source. Visit the home improvement store and talk about the various options with a knowledgeable salesperson.
To add a handheld shower head to a bathtub, you can install a diverter valve on the existing tub spout. This valve allows you to switch between the regular tub spout and the handheld shower head. Simply attach the handheld shower head to the diverter valve, and you'll be able to enjoy the convenience of a handheld shower in your bathtub.
To increase water pressure in your shower with a new shower head, choose a model specifically designed to boost pressure, such as a high-pressure or low-flow shower head. These types of shower heads can help increase the force of the water flow, resulting in higher water pressure during your shower.
