On the hunt for swishy hair......

Went to the hairdressers for my bi-monthly sort-out as I am trying to grow my hair past my shoulders!

The design this time was to have more hair at the front so its looking longer and thicker, which he has achieved, but I was seriously told off for straightening my hair too much! The eternal problem is that if I dont use my straighteners, I look like this:

But with less of the smile

 So I used my new curly bristle brush, and was equipped with my paul mitchell straightening stuff, and went to work. 45 mins later, it looks nothing like he managed to achieve! Yes its swishy, but the main adjective is frizzy. Definitely frizzy. So I had to use my straighteners a teeny tiny bit and sort out the bits at the front. Still got volume, but its in neat lines.
Anyone got any product suggestions for thick and frizzy hair to make it more manageable without being too flat? I want volume, but not like above!
Sometimes I do think the mohawk would be so much better.............
