Loose perm short hair refers to a hairstyle where short hair is permed to create loose, natural-looking waves. An example is Kim Tae-hyung's hairstyle in BTS's "Dynamite" music video.
This hairstyle gained popularity due to its versatility and low-maintenance nature. It can be styled in various ways, from elegant to casual, and is suitable for all face shapes. The loose perm technique has evolved from the traditional perm, introducing gentler formulations that minimize hair damage.
