Still, hunting for the best hair thickener for your ultra-fine hair. Make limp, listless locks a thing of the past with Aveda thickening tonic. This intensive modifying treatment instantly adds texture, thickness, and volume using a unique formula powered by botanicals. Wheat, Brazil nut, and soy proteins work to plump up hair from roots to ends, leaving locks feeling fuller without weighing hair down or leaving behind a sticky residue. Organic amla and other fruit extracts nourish strands to keep hair hydrated, healthy, and wonderfully soft to the touch while stimulating the scalp to promote better growth. This treatment offers an aromatherapy boost, too, using Aveda's own pure-fume, fragrance blend made from certified organic cinnamon, rosemary, geranium, and other pure botanical essences. To use, shake well before each application. Mist damp, towel-dried hair thoroughly and work through with a comb. Blow-dry and style as usual. Aveda thickening tonic is cruelty-free and free from parabens, petrolatum, mineral oil, formaldehyde, synthetic fragrances, and animal ingredients.
