The term "head spa" is essentially the Japanese designation for a specialized scalp treatment, as described by Shinichi Nguyen, manager of Masa.Kanai in New York City—a leading destination for these unique services. Although head spas have only recently gained popularity worldwide, they have long been a cornerstone of the Japanese beauty industry. Much like the standard "cut and color" services, the "head spa" is a staple offering in nearly every Japanese salon. This treatment focuses on rejuvenating the scalp, promoting relaxation, and nurturing hair health, making it a cherished ritual for both beauty enthusiasts and wellness seekers.
