You could spend a fortune at a salon to make your hair look good. Or, you could just grab the world's most popular soda.

Check out this life hack, in which YouTuber Ellko rinses her hair with Coca-Cola.

While drinking Coke may lead to an expanded waistline, it may actually work wonders on your mop up top.

This video first surfaced in May, but has only now gone viral. Could it be the start of a new trend? First, it's Coke in the hair. The next thing you know you're cleaning your cuticles with Dr Pepper and taking full-blown Mountain Dew baths.

What do you think? Would you put Coke in your hair or do you have some other, less caffeinated secret to keep it looking good?
