California is the specialist for those water saving heads... Some hotels have pressure but limited flow, so you get sandblasted instead of showered, to the point it's painful !

At my house we simply removed the extra donut/filter/blocker and it's perfect, I don't think you need a special shower head as much as investigating if there's a block there... Any non-castrated shower head will flow plenty with good water pressure.
