Luongo found first team chances hard to come by in Hasselbaink’s first few games in charge, with other options selected ahead of him.
However, the Australia international has now featured in QPR’s last three matches and Hasselbaink has been impressed by what he has seen.
"Massimo has given us something different," Hasselbaink said. "He’s very calm on the ball, very easy on the eye.
“Also he’s done the other side of the game. That was my worry, but he has proven to us that he can do that. Now he has to do that for the rest of the season."
Luongo was only brought to QPR from Swindon Town last summer, and supporters of the London club have largely been impressed by his showings.
The 23-year-old remains more gifted in possession than out of it, but he has shown a real willingness to adapt to Hasselbaink’s style.
The Dutchman has earned a reputation for building well organised, and Luongo has proven that he has a role to play in recent appearances.
QPR have now lost just twice in Hasselbaink’s first 11 matches in charge, but they have also just been able to claim a solitary win against Rotherham United.
