Bumble & bumble Defrizz smoothes, tames & leaves hair looking ultra sleek. This silkifying formula is much more than a simple defrizzer. It protects & nourishes every strand for hair that looks & feels more manageable, & adds softness & shininess to boot. Perfect for both curly & straight styles, it makes your day go a lot smoother! Squeeze a few drops into your palm & work through the hair with your fingers. Use on damp hair to control frizz, or on dry hair to add shine, control flyaways & add movement.
