Meet Theresa

Favorite shampoo, conditioner, hairspray: Any Aussie product.

Secret to Theresa's "big hair" style: Blow-dry the hair upside-down, use the ratting technique and lots of hairspray to maintain the fullness. Scrunch up the curls.

The worst hair mishap: The one-time disastrous professional perm that ended in hair breakage. To avoid this, condition regularly and make sure your hair is in good shape prior to perming.
