Ever had a tough time choosing the exact right hue for your nails in the salon?

There are so many to choose from, and if you regret the shade, that's fifty quid down the drain. 

Luckily, 18-year-old Emma Young recently shared her GENIUS method of colour choosing, and we're blown away. 

All you need is the plastic colour decals and your Snapchat app and you're good to go. 

'I was looking at the nail options, and the nail salon I go to has them glued inside the book so you can't put your finger under it to see how it looks,' she told Buzzfeed. 

Momentarily baffled, the teen had a radical idea.

Using Snapchat's sticker feature, she created a sticker with one of the nail shades, and placed it on her own nail in a snap. 

The final result was a Emma being able to see exactly what the shade would look like adorning her digits. 

Impressed? You should be. 

The method went completely viral after Emma tweeted it to the masses, and people have been utilising the Snapchat nail sticker hack for themselves.

We're sorted for our next salon visit!
