water pressure in the shower

we have good water pressure everywhere in the house but the master shower. is there something i could do to help this problem?
do they make a special shower head that helps this?

check the screen behind the shower head and at the shower valve.

Check the flow into a bucket. It should be around 2.5 gallons/minute from the showerhead. If you get that, it is doing its federally mandated job. Not all showerheads are created equal...some do a much better job with the mandated maximum flow than others.

i see the screen behind the shower head but
where is the shower valve you are refering to?
is it 2.5 gal/min with the shower head on or off?

The restrictor is in the showerhead...so, to see if you are getting the volume mandated, leave it on.

The other place there may be screens is in the valve assembly that controls the shower.
