The reality star, who gave birth to her son Lorenzo in August, revealed her new look on Instagram and Twitter after inviting her fans to guess which colour she was going for.
Snooki posted a photograph of herself during the dying process as well as another image of herself with her stylist Bradley Moreland.
"Love you boo, fab job as always!" she wrote. "Xoxoxo."
In further images, Snooki described her new hair as "poison ivy", "sexual" and a "fireball".
Snooki also stood by her decision to get extensions when a fan advised her to take them out, saying: "I can't, I'm obsessed with my great lengths."
Snooki, who is currently engaged to Lorenzo's father Jionni LaValle, recently revealed that she would love to add more children to their family in the future.
She recently denied rumours that her relationship with LaValle was in trouble, telling the publications involved: "Get your s**t correct!"
