Just saw this thought I woudl add some help..
After washing, towel dry upside down. While your head is still upside down, apply some mousse to the roots (only a little) blow dry upside down.
Once dry, flick your head back up the right way and smooth over, and do parting, fringe etc, on hairdryer cool setting.. DONT use a brush now just use fingers or you'll flatten it all again!
Then, once its all nice and dry, should be looking a little bouffanty now. Spray with hairspray and use fingers to pull hair up from roots, kind of a tousled look. once its as volumised as you want, spray more hairspray on and you are done!
I used to be a stylist for fashion shows by the way..
Elnett IS the best hairspray ever. Tresemme is also really good.
Wont look too 80's unless you have blue eyeshadow and bright red lipstick on. And Shoulder pads.
Anyway, 80's is back!
Have fun, let us know how you get on!
