The 33-year-old model will join the elite group of other beauties including Queen Latifiah, Zooey Deschanel and Eva Mendes to become the face of the brand, reported E!Online.
"I feel my hair has been through it all- from being styled more than ten times in one day to enjoying the sun and surf with my children - and Pantene has helped to keep it healthy with every wash, no matter what the day may bring," Gisele said.
It is believed that the new hair deal had added at least a few million to the model's bank account.
