Having a blast in the UK, Mary Kate and Ashley Olsen hit up The Arts Club in London, England last night (October 15).

The “Full House” duo kept their heads down as they exited the establishment and headed over to Loulou’s for some additional shenanigans.

In a recent interview, the Olsens’ hairstylist Mark Townsend spilled the beans on how they maintain such consistently great hair- dry shampoo!

Townsend explained, “Everything I know about hair texture, I learned from Mary-Kate and Ashley. They are blessed with having great texture and natural wave in their hair, so we don't have to spend a lot of time to get that perfectly tousled look. Their biggest secret is dry shampoo.”
