My votes on both ends of the cost spectrum: Clairol 3 in 1 which is GREAT and CHEAP, although this past week I confess I have used it with a bit of gel, because by the end of the day, with mousse, my hair gets too soft. The other is Deva's Volumizing Foam, which also gets some gel. I may eventually quit the Deva product, as I am not convinced it is so superior it is worth the price. I think I got the Clairol for $1.50 at Walgreens and it is CG friendly.
