The Same Old Love singer is often the root of our mane envy (hello, unrivalled volume) but she revealed that it's all down to being a little lazy...
Yep, you read that correctly! Just like Kim Kardashian, Selena goes days without washing her hair - even while on tour - but she says it works absolute wonders when it comes to styling.
"I don't wash my hair everyday, which may sound gross," the star told Allure magazine, "but it's actually really bad for my hair. Some of my best friends actually can't go more than maybe two days without washing their hair, and for me, I give my mum and my dad all the credit, because I have thick hair, so it gets better the less I wash it."
But how long does she leave it exactly?
"By the third day, my hair actually holds pretty well," Selena revealed. "It just holds curls better, and it holds product better. It's so strange, but it actually works. I just use a little dry shampoo, and I tease it to keep the volume up. Usually by day four is when I have to absolutely wash it."
We could all learn a thing or two, right? With that in mind, Selena also hinted that she is a true high-street girl at heart and that she eschews the salon-worthy Kerastase, Purology and Paul Mitchell products for good old Pantene.
"My entire tour is stocked with Pantene Pro-V Airspray Hair Spray," Selena told the publication. She continued, "It's so light, and I can run my fingers through my hair, which when I'm on stage and running around, that's kind of a big thing for me. I've never been the person who wants her hair perfectly sculpted all the time. I love to be able to move it around."
Her locks go through a hell of a lot of blow-drying and straightening on tour, and just like us, there's one product in particular that she totally swears by.
"I definitely love the Pantene Pro-V Smooth Serum With Argan Oil From Morocco that I've been using," Selena finished. "After the show's over, I put my hair in a bun, and I put a little bit of the oil in it."
So low maintenance - we love it!
