Head pressure is created by a column (depth) of water in a container. Pipe is considered a container. Diameter is not a factor. The higher the column of water, the more psi it creates. Multiply column height of water by .434 to get psi of water.
If water is flowing through pipe, no head pressure can build up. Blocking off flow of water will create head pressure in pipe as long as pipe is vertical. A vertical column of water creates head pressure.

most plumbing codes require 10' of head for testing purposes. Maximum head pressure would depend on pressure rating of pipe & fittings used.
Head = (Pressure * specific gravity)/2.31 Head in ft Pressure in pound per in^2
30ft rise = 13 psi (pressure is 13 psi higher at bottom of a 30ft column that at the top). Water Pressure = .433 psi per ft for a column of water at 62 degrees F.
If water is flowing through pipe, no head pressure can build up. Blocking off flow of water will create head pressure in pipe as long as pipe is vertical. A vertical column of water creates head pressure.
The recommended water pressure is 0.5 to 1 bar

There is a screen and/or a water saver in the shower head. The screen may be plugged with sediment from in the water.
the deeper you go , the more water is on your head
A shunt is inserted in the head to relieve water pressure on the brain.
I think, that's refer from your system. If you manipulate the surface pressure of the water, you will get a big value of water suction head with higher surface pressure. CMIIW....
Static === still, motionless --- Head refers to the pressure water in motion will create a 'head' just from being in motion.
possible head gasket
On the discharge line with the relief of the pressure control back to suction
mean and dirty a one foot column of water will produce 1/2 psig head
