And it's all thanks to a trick from her fabulous Hollywood hairdresser, David Babaii!
"Trick to making that scent last throughout the day?" Christina Instagrammed along with this picture (above). "My hair stylist @davidbabaii sprays it in my hair."
David has worked with many of our favourite A-list hair icons including Jennifer Lawrence, Angelina Jolie, Sarah Jessica Parker and Gwyneth Paltrow, so when he has a beauty tip up his sleeves, we tend to listen.
Spritzing scent into your hair is one of those tricks that's been doing the rounds for years as it comes under the rule of layering fragrance to create a long-lasting, lingering scent.
Some say that the alcohol in a bottle of fragrance is bad for your hair as it dries it out, but to be honest, we can't see how it's any worse than dousing it with hairspray.
And if you spray perfume on your skin on a daily basis, surely it can't be THAT terrible for your locks?
Also, there's nothing better than getting a whiff of your beloved scent as you swoosh your hair of a night out, so we say, heck, go for it.
Maybe don't literally smother your tresses in the stuff, but for a special occasion? If it's good enough for Christina, it's more than good enough for us.
