I feel this adds only slightly more volume than an everyday mousse, but when I don't use it, I can tell a difference (if that makes sense). I actually apply this to the roots of my wet hair along with Tresemme Flawless Curls Extra Hold Hair Mousse. I love anything from TIGI's Bed Head line and was able to buy a few bottles of this that were marked down considerably at Ulta. It smells delicious and I'm a sucker for fun packaging. I don't know if I'd repurchase again at full price.
