Top notes, also known as head notes, are the initial scents that you perceive when you first apply a fragrance. They are typically light and volatile, evaporating quickly within the first 5 to 15 minutes. Common top notes include citrus scents like lemon and bergamot, as well as fresh herbs like mint. These notes create the first impression of a fragrance and are designed to be uplifting and refreshing. While they fade rapidly, they set the stage for the heart notes that follow, which develop after the top notes dissipate. Understanding top notes helps in choosing a fragrance that suits your preferences.
