How-to: French girl hair starts with a voluminous blowout. Begin on damp hair and add a generous amount of styling foam. Divide hair into 3-4 horizontal sections depending on the thickness. Use a medium-large round brush and a hair dryer with a smoothing attachment. Work from the bottom section upward round brushing hair smooth adding volume with a slight bend at the ends. Once hair has been blown out create an imperfect center or side part and style as desired. French girl hair is meant to be effortless. Add dry shampoo throughout the week to refresh style until your next blowout.
