Christina Applegate has got a razor-edged hairstyle which gives her a perfect look. To get her hairstyle use a volumizing shampoo and wash the hair, then apply a volumizing mousse after the hair becomes dry. Next blow dry the hair using a paddle brush to get more volume and avoid using round brush on as it may cause the ends to curl. Take a straightening iron and use it on the upper ends. Make sure that the hair frames the face in front and then apply a glossy shine spray to add more shining to the hair as well as look beautiful.
