Bilson Ad for TRESemmeRachel Bilson has been a model for many products and after browsing around I found a great picture of her for her new ad campaign for TRESemme. I love this hairstyle but it looks hard to get done without some very professional help. The hairstyle is a chignon style look without a tight bun and instead looser sections are tied together. The front of the hairstyle is amazing with a long sweep on one side. I wish they would load the video for doing this exact look as many of my friends are not able to style this look so well. Here is the picture and a great site to visit is http://style-seeker.tresemme.com
