The 23-year-old debuted a fiery new hair color during her appearance at a New Jersey mall in Freehold on Saturday.
The day before, she and her go-to hair pro Bradley Moreland of NYC's Gemini14 Color Bar Salon tweeted several pics leading up to the her big hair makeover reveal.
"Thank u my love @BradleyStyleNYC for the intense hair workout lol!" the star tweeted with a pic of the final look.
Moreland, who also spiced up Snooki's 'do with purple Great Lengths Extensions this summer, used Goldwell color to achieve the starlet's ravishing red locks.
This isn't the first time the reality star turned entrepreneur and author has been in the red -- she dyed her hair "fireball" in July 2010, just days after she officially ditched her trademark pouf.
