Tip: For a special occasion, try adding a hair piece (like Knightley's) for updos. It will give the illusion that you have a lot more hair. This is also good for short hair. Check out hair extensions in our reviews section.

Tip: Volumizing products are a must. Try a volumizing gel or mousse for a boost when styling. And stay away from leave-in conditioner, which just weighs down fine hair. Instead, use a non-sulfate shampoo. It's less drying so you'll need less conditioner. (One to try: Alterna Life Solutions Volume Restore Shampoo, $24.)

Tip: Opt for a blunt looking cut, so no layers anywhere but around your face -- they can make you look like you have less hair. See how Paltrow's blunt-looking cut looks more full than Momsen's layers?
