Emma Roberts reveals how long she goes without washing hair on vacations

Emma Roberts is letting fans in on her low-maintenance vacation hair routine.

The actress, 34, began by confessing that she tries to go on without washing her hair on vacations for as long as possible.

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

The actress added that one reason behind it was her reluctance to use resort products on her freshly dyed "sunrise red" hair.

"I've washed my hair when I've just dyed it and it's turned a crazy colour. 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," she told the outlet.

She admitted that she avoids washing her hair while vacationing for up to five days. "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," Roberts said.

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

Roberts has rocked several hair colours over the years, including her natural brunette as well as varying shades of blonde. The actress first debuted her sunrise red locks in February.
