Ndjoli has now been on loan at the Scottish side three times. He was the top scorer in Scotland's first division last season with 18 goals.
He will be there until January this time around. And he hopes to pick up even more tips from Boyd in those months.
Ndjoli told The Herald: "I'm learning from Kris Boyd every day in training.
"Every training session so far he has pulled me aside and told me what he thinks I can do in and around the box.
"He's told me 'touch and finish'. Sometimes I take an extra touch in training but every day I'm learning from him.
"The manager (Steve Clarke) has worked with a bunch of young players and helped them kick on in their careers."
