Alyssa Milano has the right idea here with her unique, yet simple updo prom hair style.
Extra height is created in the crown area by gently back combing small sections of hair before pulling all the hair back into a low chignon.
Hair is twisted into a chignon and pinned in place with hair pins. Front bangs partially drape across the face from a deep side part.
Add stunning earrings to this look, and maybe a jeweled tiara and you will look great for the prom in this style.
You may want to practice creating this hair style on you own a few weeks before the prom. If you don't feel confident with doing your own hair you can always schedule a trial run at your favorite stylist.
Make sure you book your actual appointment for the day of the prom weeks in advance as many stylist book up quickly and may not have an opening for you.
