Didi Conn, 74, Stars in New Beauty Campaign!

Grease star Didi Conn has returned to the spotlight in a new beauty campaign.

It comes nearly 50 years after the 74-year-old actress made a splash in the 1978 film starring and the late .

In a new Laura Geller Beauty ad, Conn riffs off her Grease storyline – in which her character Frenchy was a 'beauty school dropout,' complete with a plot-defining song.

'Hi there. You might remember when I famously dropped out of beauty school. I thought my life and my hair was ruined and I'd have to spend eternity making expensive salon appointments,' she said in a clip shared on social media Tuesday.

The monologue plugged the brand's Full Root-ine Hair & Brow Concealing Cream and Powder.

In a nod to Frenchy's status in the high school girl group Pink Ladies, the clip showed her clad in a pale pink dress with a pleated skirt and name tag.

Conn, whose hair was mistakenly dyed a gingery red hue in the beloved movie-musical, looked chic with a brunette bob.

In the decades since the career-defining film, she has brushed off claims that Grease is sexist.

Conn continued: 'She failed, she had a few problems in the tinting class over there. She still cared, especially for her friends. 

'So when Sandy is all alone by herself after the car race and she decides she wants to be part of the gang, she wants to have fun and allow herself to be emancipated a little bit. She says to Frenchy, "Can you help me Frenchy?" you know.

'So, it's like the first makeover show, she is becoming more of herself. She is allowing herself to come through.

'It's not so much to get her man but it's to be who she is 100%. He ran away from the dance because he was dancing with Cha-Cha and she couldn't confront him because there was this part of herself that wanted to come out.'

She noted that despite Sandy's innocent appearance, she was secretly hoping to bring out her sexuality, which sets the stage for her makeover by the film's end.
