What Is TikTok’s Scandi Hairline Hair Color Trend?

Though you may immediately assume that the Scandi hairline only works for blonde and straight hair, it’s actually well-suited for all hair types. “This is why I love to say it refers to the technique and application, and not just the idea of a bright blonde,” says McMahon, who adds that it looks equally impactful on brunettes and curly hair types (though she does caution against trying a Scandi hairline if you have natural dark red or copper hair). “This technique is only recommended when you have had a full head of foils or part foil service to back up the result, ensuring the color looks naturally enhanced.”
