@Jessiebanana: I've heard good things about that Suave mousse too, and it's only $3!
I haven't used mousse in a long time, but at that price it's certainly worth a try. It's hard to find in Walgreens around here though, even here in SF. I did spot a couple of bottles of it in another neighborhood yesterday though - will have to go back and buy one.
The last time I used a mousse was when LA Looks still had their Gel2Mousse product which was fun and actually worked pretty well on my hair. Currently I'm just using the ever-popular LALSG.
