The Osis+ Mess Up product is exactly what you're looking for if you want that "just woke up" style. What's really nice about it is that if you work it into dry hair, it disappears, leaving you free to style without the product being obvious, like a shiny gel. It's also incredibly easy to rework throughout the day, no extra product needed. As for how long the product lasts, it kept my hair nice and messy through a concert and the product was still workable the next day! Overall it's a great styling aid, and I will continue to use it.
