AUSSIE MOUSSE + LEAVE IN CONDITIONER: I absolutely LOVE this mousse. When I curl my hair, it helps keep the shape without it being a harsh crunchy curl that some other hair styling products cause. I also like to use a little in my hair when I am straightening it to keep the fly-aways at bay. It is a 6.8oz bottle that Aussie sells in 4 different holds. Flexible, Strong, Maximum, and Extreme. I always buy the flexible one but if you feel you need more of a hold, there are definitely options.
