I have straight, flat, thin hair and i want it wavy with a little more volume. Any suggestions?

I have had good luck using a mouse (Tresseme) and then when my hair is almost dry, just the slightest amount of dampness to it, I roll my hair into Velcro rollers. I sometimes will blow it dry for 2-3 minutes, or I let them stay in my hair for about 15 to 20 minutes, then unroll them and my hair has real nice body. I use smaller rollers on top of my head to really give it some lift. Hope this helps.

I have the exact same problem. This is what I have done. After washing and drying your hair, spray the crown of your head with hairspray and tease your hair with a fine tooth comb. It takes a few times to get used to the process but you will have it down in no time.
