If there are supply valves feeding the supply lines connecting your faucet, they may be closed, or simply your faucet components/inserts and or supply lines may be restricted.
ANS 2 - most common cause for this is a plugged aerator or stop valve.
It may be that your shower head is clogged with minerals. Try using a mineral/lime cleaner like CLR or LimeAway. You can buy these at large chain stores or hardware stores. Pour the solution into a bowl and soak the shower head for 5 minutes or so (longer if needed). You can also take the head off and soak in the solution.

maybe your hot water tanks gas valve blew out-- you willl need to buy another valve to replace it or maybe a whole new hot water heater if the hot water heater is about 10 years old or older.

Remove the shower head and clean out anything that might be blocking it, such as hair or debris. Replace the shower head and turn on the water; the water should be running.
A power shower head mixes moving air with water, to increase the strength of the water coming from the shower head, while using less water. The advantages are lower water bills, using less water and protecting the environment. Some reviews of power shower heads indicate that the claims are untrue, and that the product does not work as is a waste of money.
When you pull the stem up, it diverts the water from the tub spout to the shower head. Somewhere between the valve connection and shower head arm, you have a leak. The easiest part to check would be the arm that comes out of the wall that you screw the shower head on to. It is normally screwed in to a "shower Ell" and that connection and or pipe is easy to crack if someone pulls on the shower head. Pull the escutcheon plate towards the shower head and try to see into the hole and look for water at the connection. It would only leak when you are using the shower. If it is another connection or the riser pipe itself, you'll have to access it through the wall, hopefully from a room on the opposite side of the wall. Good Luck
