Reminder, as reported in the September edition of Elle Magazine, today is the day you will be able to bring a bottle of any shampoo to any Saks Fifth Avenue and receive a free full-size bottle of Fekkai Advanced Shampoo in exchange.

This is absolutely crazy – in a good way! The offer will be one per customer while supplies last – and I have no doubt the supplies are going to go really, really quickly!

Click here to see if there’s a Saks Fifth Avenue near you.

And here’s a list of the participating locations.
