Hi sugaree, as a fellow wavy/curly I know exactly what you mean!

Have you read "curly girl" by Lorraine Massey? There are tips in there about how to achieve height and body in the canopy.  One of the best tips is to do little finger curls and pin them so that they sit up (at right angles) to your scalp. You only need maybe 3 or 4 down the centre of your head and when they are almost dry, you take them out and leave them (separate them a bit) alone.  I find my hair looks best when I totally don't touch it!  Also, use a microfibre towel to dry the roots a bit whilst you are hanging upside down, this should help to give them a lift.  I think when you let them air dry from sopping wet, the weight of the water can straighten your roots.

Hope that helps you!!!

PS: I recommend that you STOP blowdrying your hair immediately. It's not good for any hair-type, but especially curlies. Air-drying is best. You just need to practice with techniques and products to get what is right for you.   (btw, the pics in my sig....I have NO product in my hair at all and it was left to air-dry)
