I have my hair cut in a chin length messy bob. My hair is dead straight and very fine and I just can't get it to look decent! I've had this issue for 18 months now and have a 20 year school reunion coming up and don't want to spend the evening of that getting upset about my hair!! I need some advise on what I should be doing to it to make it look 'messy' but nice? It just looks plain messy and daggy ATM. I have hardly any knowledge of products so simple language will be welcome!
