Add flexible hold to your hair -- without weighing it down -- with Aveda Invati Advanced Thickening Foam.
In an instrumental test with subjects using this product once, the foam was shown to add immediate volume that lasts all day and immediately shown 5% thicker hair.
How do I use it: Pump three to five times into hands and emulsify. Distribute evenly through damp hair from roots to ends. Blow-dry and style.
