Guys with permed hair are men who have undergone a chemical process to create curls or waves in their hair. This can be done for various reasons, such as changing their appearance, adding volume, or emulating a particular style. A famous example is Paul McCartney of the Beatles, who sported a permed hairstyle in the 1960s.
Perming hair has gained popularity over the years due to its ability to add body and texture to fine or limp hair, making it appear thicker and fuller. Historically, perming was primarily associated with women; however, in recent times, it has become increasingly common for men with permed hair, with celebrities like Zayn Malik, Harry Styles, and Justin Bieber embracing this style.
