I had something like that happen a few years ago - went for a two-hour drive down the interstate in a friend's convertible. Not knowing that we were going to have the top down, I didn't bring anything to pin up or tie back my hair with. By the time we arrived, it was in one huge knot - it took a good hour and most of a bottle of detangler spray to fix, and I still lost handfuls of it! Whoever said "beauty knows no pain" never had long hair! Hope you're having a wonderful week!
