'Poison' hitmaker Nicole Scherzinger has admitted that shooting an advertising campaign for haircare brand Herbal Essences was "empowering" and she really enjoyed taking part in a commercial led by a strong female figure.

Speaking to Britain's Hello! magazine about the commercial, the songstress explained that the women who star in Herbal Essences advertisements are usually authoritative and confident, which was something she liked portraying on set:

"I got to fly to an exotic place and play this really strong, empowered woman for the day. It was wonderful. The ad is all about having a busy life and then escaping for 10 minutes while you're in the shower to this fantasy world where women rule."

"I approached it like I would a movie role. In the next commercial my music will also be featured, so it's like a music video."

She added that making sure her own hair looks great is often a priority and she always goes out of her way to maintain and take care of it: "It's my natural colour and all my own hair. Sometimes when I perform I might wear a hairpiece to make it easier to style, but I am of half-Filipino, half-Hawaiian descent so it's natural."

"For me, the best hair has volume. I like to tease the roots before I curl or set my hair. It must be the Southern gal in me."
