Aveda Smooth Infusion Perfect Blow Dry treatment provides an anti-frizz shield for 72 hours, wrapping each strand in an invisible anti-humidity shield that locks out humidity and keeps frizz-prone styles 5x smoother and sleeker for longer. This 100% vegan formula also contains UV filters, protecting shiny, sleek blowouts from the drying effects of the sun and heat styling up to 450°F. Its anti-frizz, plant-derived technology features a plant polymer shield, an invisible polymer that instantly cloaks hair strands and repels water, providing silicone-free protection and is 99% naturally derived. The botanical smoothing oil blend features Kalahari melon seed oil and Tamanu oil, which smooth and condition cuticles for softness and shine. Harvested and cold-pressed in Southern Africa and the South Pacific, respectively, these oils are rich in fatty acids. The product has Aveda's own pure-fume™ aroma with Australian Sandalwood, Bergamot, Palmarosa, and other pure flower and plant essences. It is suitable for all hair types (fine, medium, thick) and all textures (straight 1A, wavy 2A-2C, curly 3A-3C), and is safe for color-treated and chemically processed hair. Aveda is a cruelty-free brand and does not conduct animal testing. The product is free from silicones, mineral oil, gluten, sodium lauryl sulfate (SLS), sodium laureth sulfate (SLES), and synthetic fragrance. Aveda's products and packaging are made with 100% solar and wind power, and they are a pioneer in using 100% Post-Consumer Recycled PET bottles. To use, shake well and apply to damp hair, requiring blow-drying to activate. For best results, do not apply with other pre-styling products. Begin with clean, towel-dried, detangled hair. Working in sections, spray generously from roots to ends. Blow-dry thoroughly to activate and seal the formula.
