...should I use? I want some for the following (although not necessarily in the same bottle/container):
*De-frizzing my hair
*Adding extra volume to my hair
*Something to helping me give that "messy" look (perhaps a mousse?)
*Something to help curl my hair
*A protective spray for when I straighten my hair
I heard that the following brands are very good:
*Tigi Bedhead
*VO5
*Shockwaves
I've heard good things about Tigi Bedhead because it's a salon brand but I wondered whether it's really worth the money or not. I was thinking perhaps something not as important/hard to find a good one such as the heat protective spray, I could get from VO5 and the de-frizzer I could get from Bedhead.
I have medium length hair with bangs/side fringe. It's naturally wavy and quite frizzy but have managed to sort of tame it for a while but I still seem to get quite a few fly-aways/frizz.
So, any suggestions on specific products from those three brands? Thanks so much!

Oh, and I forgot to mention that I currently use Tresemme Smoothing Serum but I'm not sure if it's helped or not...
I've also thought about buying Garnier Fructis products...
