Can anyone recommend a good app for "trying on" hairstyles?

Before I make any terrible mistakes! I think it's time for a change, long to short or maybe a fringe, but want to "try" it beforehand if possible!

Me too. I tried one once but it was so terrible not worth it.

Oh thank you for your replies, this is not promising though is it?!
