Retro hairstyles are styles that were popular in the past and have recently become fashionable again. Two of the most iconic retro hairstyles are mullets and afros. Mullets are characterized by short hair on the sides and back, with longer hair in the middle. Afros are characterized by a full, rounded shape with tight curls. Both of these styles have been popularized in recent years, making them a great choice for those looking to make a statement with their hair.
