Design.ME Hair FAB.ME 18-in-1 Leave-in Treatment. That’s right – eighteen awesome things in one treatment product. This product is my solution to a lot of hair woes. Mainly, it gets my hair from a crazy bird’s nest appearance to something a lot more healthy looking and manageable. I had a mini travel sized version of this on my honeymoon and almost cried when it ran out before the trip ended. I definitely had some bad hair days before I came home without it.
