a convincing lie is to tell someone you are a model for hair dye boxes. these are some ways to make it believable:

1) KNOW YOUR BRANDS - don't mix-up your garniers with your clairols with your loreals. look smart!

2) KNOW THE NAME OF THE DYE YOU MODELED - is it chardonnay or ginger ale? be sure.

3)IF YOU GET CAUGHT - act like you were joking the whole time. besides, who lies about being a hair dye box model?
