Free Fekkai Shampoo! This Thursday September 17th is the day! Saks & Fekkai have teamed up to offer a shampoo swap. Just bring in a bottle of your current shampoo (an empty on even) to any participating Saks Fifth Avenue store and you can swap it for a free bottle of Fekkai Advanced shampoo of your choice. It’s Fekkai, it’s free, and it’s only this Thursday!
