Similar to Hair Color, the Hair Color Booth app lets you experiment with your hair colour in crazy shades. You can also select just some of your hair to try different colour streaks or ombre colour combinations. This is a great app to freak out your mum or friends too! There's only a few colours in the free version but it's enough to try some rainbow hair.

"The color won't be even when you rinse it out," says Ionato. "Leave it down until the timer rings."
