Terrence Davidson has quit his role with the 'Pound The Alarm' star, citing creative differences as his reason for leaving.
"I've decided to step away as hair stylist and wig creator for Nicki Minaj," he said in a statement to MTV.
"It has been an amazing experience offering me a chance to express my creativity and exhibit my love for the art form of wig design."
Minaj has displayed a noticeably toned down appearance in recent weeks as she promotes her upcoming stint as a judge on American Idol.
She said of her new role: "The human side of you comes out eventually, when you're looking at people that are this close to fulfilling their dream.
"In their head they have already seen it come to fruition, so saying no, it's like a dagger."
