In my opinion, one of the best shampoo commercials ever belongs to Pantene with its "I Believe in Miracles" ad starring model Estel Rovira. Not only does Estel look amazing, but the commercial truly shows off how gorgeous her long brown hair is as you'll see below. Her "Flower Shop" Pantene ad is also the stuff of legend for Estel and her amazing hair. Being that today is her birthday, let's take a look at why she and her hair are so memorable in her famous, now-classic Pantene ad.
