I use Bedhead 'Queen for a Day' before blow drying. It's nice and light spray and smells nice, one can lasts for ages. If I don't use that and don't blow dry, then my hair always seems a bit wispy and flat. If I want it to stay put and I'm going somewhere 'nice' I also floof it up and then drown it in Elnett hairspray.
Bedhead products are all good.
Also Avon Advance Technique refresher (dry shampoo) I use this on the next day after shampooing spray under the hair near the roots, wait a few mins then massage in and brush it gives instantly thicker hair.
