Dry shampoo, Bumble and Bumble hair powder (comes plain or in colors), and when you do shower wash it, only put conditioner on the hair from the neck down - never on your scalp. Conditioner is a real contributor to scalp residue. Brush it as little as possible and only brush the bottom.
Also, buy some cute hats! Some days I just throw on a baseball cap with a ponytail through the hole in back. Beanies are super cute in winter with your long hair hanging straight down or in a behind-one-ear side ponytail and then you drape the ponytail forward over your shoulder onto your chest. If it's cold where you are, a beanie with ear flaps and long tassels is so fun.
A Kangol hat is a sharp look any season. In the spring and fall a Cloche looks adorable! A Cloche is perfect with your hair in a very low side bun behind one ear. A lot of women are wearing Maus and Newsboys, but those aren't my favorite - just a style preference. I would love to rock a Fedora but I would need a little more courage for that. I tend to think they look best on skinny chicks and it's more of a night-time look in my opinion. College girls can wear a Fedora during the day, but I would only wear one if I were going out. Since I have three kids that's rare.
