I found several with a Google search but as soon as you reach the second page in the sign up (good thing I use fake email address!), it asks for your credit card. Stellure was one that did this. Ladies Home Journal has a pretty good one (which is actually the 'makeover game' recommended by allinaugust!) but with limited styles and so you have to pay $14.95 to upgrade if you want to see the other styles.
I was getting tired of signing up and then being told that it wasn't *free* afterall.
Any other suggestions with a LOT of hairstyles to choose from -- free? Maybe one of you might have found a site like this that you have personally used...
I am now wishing that I had my old Cosmo Makeover computer CD, but I sold that at a yardsale at some point. Silly me.
