If you’ve fallen down the Korean beauty rabbit hole and consider yourself someone who knows her stuff—whether browsing Olive Young’s best products or knowing the difference between an ampoule and a serum—you probably already know that Korea’s approach to hair care is just as layered as its approach to skin care.
In addition to the clarifying shampoos and nourishing masks that are already well-known in the United States, Korean scalp tonics are just beginning to generate buzz. Korean hair expert Park Jehee describes it as a lightweight treatment that, if used consistently, can help reduce scalp heat, deliver nutrients and support overall scalp health, ultimately making hair stronger and more elastic.
Vogue’s Favorite Scalp Tonic
While many of us Americans are just getting into scalp serums and brushes, we still have a long way to go. Thankfully, most Korean brands are now widely sold within the United States, making it easier than ever to reap these benefits without having to hop on a flight east.
What follows are six of our favorite scalp tonics, from calming formulas to strengthening picks, plus expert insights into how tonics work and how Koreans keep their hair healthy.
Best overall performance: Aromatica Tea Tree Purifying Tonic
- why we like it: According to Korean hair expert Oh Jihye, insiders call this tonic a “scalp deodorant” because it’s formulated with tea tree oil and is a savior for oily, troubled scalps. She notes that it instantly removes excess sebum and dead skin cells, helping to relieve itchiness and keep your scalp feeling fresh. “Its refreshing, cooling finish transforms a humid scalp environment into a breathable one, making it a must-have after a workout or on a hot summer day.” Not only that, but the packaging is chic, and it’s always the first question people ask when they peek into my bathroom.
