In most there is a washer in them that has a small hole in it so that only so much water can get through regardless of how much pressure is behind it.
About 1.25 gallons per minute.
you have trash in your line take the shower head off and remove trash or possibly in water valve at shower
Open up the actual shower head and remove the factory fitted restrictor.
300mm is a very low head, you can't expect much flow through that pipe, but you can work it out from the mechanical energy balance equation.
The flow rate for a shower typically ranges from 2 to 5 gallons per minute (GPM), depending on the showerhead design and water pressure. Standard showerheads are generally designed to deliver around 2.5 GPM, in line with efficiency standards. Low-flow showerheads can reduce the flow rate to around 1.5 GPM or less, helping to conserve water. Monitoring flow rate can be important for both water conservation and ensuring adequate water pressure during use.
To conserve water.
A high pressure low flow shower head can help save water and energy, reduce water bills, and provide a more powerful and invigorating shower experience.
Using a low flow high pressure shower head can help save water and energy, reduce water bills, and provide a more powerful and invigorating shower experience.
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.
My shower head has low flow issues and is making showers uncomfortable. What kinds of shower heads would you recommend for faster flow but still aesthetically pleasing?
To fix a low pressure shower head, you can try cleaning the shower head by removing any mineral deposits or debris that may be clogging it. Soaking the shower head in vinegar can help dissolve any buildup. You can also check the water flow restrictor and remove it if necessary to improve water pressure. If these steps do not work, you may need to replace the shower head with a new one that is designed for higher pressure.
To fix a low pressure issue in your shower head, you can try cleaning the shower head to remove any mineral deposits or debris that may be blocking the water flow. You can also check the water supply valves to ensure they are fully open. If these steps do not improve the pressure, you may need to replace the shower head or consult a plumber for further assistance.

Standard high-flow aka unrestricted shower heads made before 1995 were water-guzzlers. As of 1995 shower heads must be low-flow, with a rate of 2.5 gallons per minute.
A dirty or clogged screen can cause the low water presser remove shower head and clean. If not it could be calcium deposits built up on shower head if so soak shower head in a cleaning solution for several hours if that dose not work buy a new shower head. (note some shower heads have a low flow re-stricter in some cases you can remove this and get more water pressure)
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.
Check the shower head and clean and flush it. It may just be a little particle of junk in the head restricting your flow
