BOTANIST Botanical Hair Mask Smooth is a Japanese hair treatment mask with a grapefruit and rose scent, designed for low-porosity dry hair. This salon-quality mask contains plant-derived ingredients including squalane, 11 amino acids, and botanical extracts like avocado oil and ceramides. The lightweight gel-cream texture penetrates deeply to repair and moisturize hair, leaving it silky smooth and frizz-free. Best suited for those seeking lightweight hydration without heaviness, particularly those with fine or straight hair that gets weighed down easily.
