Demi Moore just ditched her signature length for a major short hair transformation at Cannes

We'll always have time for Demi Moore serving us beauty inspiration, especially when it comes to her hair. Speaking of which, the actress just rounded off nearly two weeks of great hair days at Cannes by stepping out on the red carpet with a major short hair transformation.

We've said it before, and we'll say it again, bob hairstyles boast the ability to transcend the list of 2026 hair trends thanks to their chic, timeless and versatile nature. One of the most powerful haircuts of all time, not only are bobs flattering, but they are also practical, requiring less drying and styling time than longer locks.

If you've put two and two together, you might already be able to guess what haircut the actress just debuted – yes, a bob. Oozing Hollywood glamour, the shorter style created enviable volume and shine within Moore's strands – and we're taking notes of the exact products behind it all.

Demi Moore's dramatic hair transformation at Cannes Film Festival

Jury member Moore graced the red carpet of the "La Bola Negra" screening at the 79th annual Cannes Film Festival wearing a gorgeous sapphire blue strapless gown custom made by self-portrait and a standout diamond necklace. However, our attention couldn't be pulled away from her hair.

Demi waved goodbye to her recognisably lengthy locks as she showcased a voluminous, shoulder-grazing bob. The cut was then styled with bouncy, large curls and flipped over into a side part to give the hair a fuller appearance. The actress's hairstylist, Dimitris Giannetos, posted behind-the-scenes clips of the getting ready process on Instagram, dubbing the look 'De-Marilyn Bob' – a nod to Marilyn Monroe's popular hairstyle in the 50's.

That said, many Instagram users have been debating whether a wig is behind the dramatic hair transformation, as the actress has done this before (ahem, we're looking at Demi Moore's short hair styling from last spring).

While the jury is still out on the wig question, we took a closer look at the post in order to scout out the exact buys that were used to give the strands body, bounce and an enviably healthy shine – spoiler, we uncovered them all.
