How do I make it wavy (all day long!) and fuller....

I do too. you can spray your damp hair w/ hairspray and put your hair in a loose braid(s) before you go to bed. When you wake up, take the briad(s) out, shake your head around a little bit %26amp; a little more hairspray. Another thing I just heard of is to wrap wet hair in sections on top of your head and secure the sections with tear-ties (the kind that come with regular garbage bags) before bed. The tear-ties are supposed to make it a little more comfortable to sleep. One last thing - get a spray w/ some sort of salt (sea salt) in it. It should help your hair look fuller.

All day. If your hair is thin I bet a curling iron won't work. So options is a perm, or try the products that will help you keep your curl from a iron in longer. Next time you go to the salon talk to your stylist about what your options are.

Sorry without seeing and feeling your hair I do not know what can help.

I also have very fine straight hair. The best thing that I've found is a short cut, a lot of layers and a lot of hairspray. I've tried so many products for my hair and most of them just weigh my hair down and make it look dirty. I do like Amplify though, it helps to keep a bit of fullness. It's the product that you spray on the roots and then blow dry.
