(Cover) - EN Star Style - Liv Tyler's gorgeously shiny locks are down to oil treatment, according to her hairstylist.

The Hollywood actress, 33, is celebrated for her luscious brunette mane and naturally beautiful features.

Celebrity hair expert David Babaii says that he uses Couture Colour Pequi Oil Treatment on the beautys hair to achieve her super glossy tresses.

"Pequi Oil gives me the hold and shine I want for all my celebrity clients. It gives me a healthy, shiny finish every time I use it," he told Style List.

The hairdresser says Livs styling routine is very simple to re-create. To achieve the stunning stars natural look, he disperses hair oil throughout the hair before rough blow drying and using his hands to style. David advises using a large-barrel curling iron and allowing the curls to release naturally in order to keep Livs signature unkempt-but-beautiful look. He also runs his hands through each of Livs curls to define the waves. (C) Cover Media
