To get a shaggy hairdo, the hair must be grown out, styled and shaped until it evolves into a look that is flattering and appropriate for a person's age and facial structure. Once the hair starts to appear too long, it is time for a visit to a hairstylist so that he or she can create an actual style.
It is vital to see a stylist who is comfortable using his or her styling implements to reshape the hair. Many stylists use razor scissors and thinning shears when creating shaggy hairstyles. The razor scissors give the hair a textured, layered look, while the thinning shears decrease the volume of the hair. Once a person has the desired shaggy hairstyle, a regular trim every 6 to 8 weeks can keep the hair looking its best.
