What is the best hair product to volumize hair without weighing it down?

I have fine hair, and it needs a lift.





Unfortunatly my hair seems to get dirty (greasy) quickly.





I am reluctant to use hair products in fear that it will make it worse.

i use the best volumizing spray. it is called ';big,sexy hair-volumizing spray'; it is like a spray mousse. after drying your hair, lift your hair up where u want the volume added. spray a SMALL amount along the roots. repeat as needed. i use a comb to separate my hair into sections horizontally. like spray a straight line acroos the back of ur head near the crown and then across each side of ur head right above ur ears. it is a little expensive(like $18-$20), but it lasts like forever! seriously, my hairstylist told me it should last @ 6 months. you can find it in most salons. it is in a really tall red can. it is very light and easy to use. i love it! hope u do too!What is the best hair product to volumize hair without weighing it down?
blow dry your hair upside down or use mousse. =]
use the yellow sunsilk shampoo, conditioner, and 24/7 creme. it hepls me. you can use that, or you can buy something called 'herbal esences natural volume bodifying foam'. its about 3 bucks and works like a miarcle.
