Speaking with the publication, Emma broke down how, while she's away on a trip like Puerto Vallarta, Mexico, there are two constants: reading books by the pool and avoiding shampoos and conditioners.

"I try not to wash my hair on vacation. I put my hair into braids and jump in the ocean," Emma said. "That's what I do instead of shampoo and conditioner."

Emma explained that she's run into problems when mixing her freshly colored hair with random hotel products, so she opts for the more natural approach of an ocean cleanse. "I've washed my hair when I've just dyed it and it's turned a crazy color," she said. "When I have blond hair it's turned yellow, and when I've had red hair it washes it all out. So I get so scared to really give my hair a real wash."

According to Popsugar, Emma goes as long as five days without washing her hair. "I try to get a blowout the day before I leave for vacation, and then I will ride that blowout into the dry-shampoo end."

"I don't care, I just dry-shampoo and jump in the ocean," Emma added. "I have no shame about it . . . Nothing looks better than saltwater hair."

So, there you have it! If you were wondering why Emma was all smiles in that viral video on the beach, it's probably because she can't wait to jump into the ocean to naturally wash her hair.
