Permed hair for guys, also known as a "perm," is a permanent wave or curl hairstyle achieved through a chemical process. This treatment alters the hair's structure, creating defined curls or waves that can last for several months. A notable example of a perm is the "wavy perm," which creates soft, loose curls that frame the face, as seen on celebrities like Justin Bieber and Timothe Chalamet.
This hairstyle has gained popularity due to its ability to add volume and texture to fine or straight hair. Perms can also be used to enhance natural curls, making them more defined and manageable. Historically, perming emerged in the early 20th century as a way for women to achieve the popular bobbed hairstyles of the flapper era.
