We just got word from our friends over at Premium Grade Hair, that FrédéricFekkai is having a shampoo swap. I got really excited since I've been wanting to try it out for some time now. I actually read on Kourtney Kardashian's blog that she uses Frédéric Fekkai glossing products and it helps keep her dark lucious locks nice and shiny. The swap is taking place on Thursday, September 17th. You simply visit any participating Saks Fifth Avenue stores and bring in a bottle of shampoo you are currently using to swap for one FREE 8oz bottle of shampoo from the new Fekkai Advanced hair care line (retails for $23). It's for one day only and while supplies last (one per customer). Click here to find a Saks store near you.
