Dame Helen Mirren's Beauty Secret? She Cuts Her Own Hair

At 69 Helen Mirren is one of Hollywood's most iconic stars. She looks flawless at every red carpet turn, but it seems she's far from high maintenance.

Speaking to Redbook ahead of the release of her new movie, The Hundred-Foot Journey, she shared her beauty secrets and admitted she usually cuts her own hair. Saying she finds going to the hairdressers for a trim every six weeks too much like hard work, she insisted: "so I only go about once a year."

And revealed that in between professional treatments: "I get out the scissors and do something, usually rather disastrously. Sometimes I'll even chop my hair the morning of a big red-carpet event."

Not so disastrous if you ask us - she's responsible for one of Hollywood's most copied cuts. We wonder if it was Helen herself who was responsible for the awesome pink pixie cut she rocked at the 2014 BAFTAs.

Helen's pretty thrifty across all aspects of her beauty routine, as sharing her favourite face wash, she admitted she mainly uses products you can purchase at your local pharmacy: "Lately I've been using a Kate Somerville face wash, but I'm also a great believer in drugstore products. You don't have to spend a lot of money to get quality stuff nowadays. A brand like L'Oréal has amazing technology."

Though it seems her biggest beauty secret is just to be true to herself and have fun on the red carpet: "it's a silly, amazing moment to be caught up in, and then it's all over. What's nice is that I don't feel nervous about it anymore. I can just enjoy it."

Too right, Dame Helen.
