Here are a few tips to get her look.
1. Start with dry hair (yes, dry hair)
2. Use a wet hairspray like Aveda's Firmata spray all over the front of your head back to the crown (the portion that is going to be slicked back)-using a generous amount of hairspray.
3. Take a fine tooth comb, comb the hair back into a ponytail-spray some more.
4. Braid the ponytail and then wrap around into a bun
5. Secure the bun with bobby pins or hair pins
