How to do Rachel Bilson’s long wavy ombre hair?
The hairstyle is quite simple to achieve. Firstly part the hair to the side and give an allover spritz with a volumizing sea salt spray. Give the hair a tousle and leave to dry naturally; your hair will do the rest. The beauty of the ombre look is it adds a touch of color to an otherwise monotone palette; and because it is only the lengths of the hair that is colored, there is no need to touch up those unsightly roots as the hair grows.
