ALL it took to set the fashion sphere on fire was a single photo posted by Nicole Kidman on Instagram. The Australian-American actress appears with short hair in a strawberry blonde tone, facing a rainbow. A pixie cut that has unleashed passions on the web and is winning unanimous approval. It's even looking like it might end up being the must-have hairstyle of the coming fall season. Time to head to the salon!

Influencers and fashion icons setting the tone for major fashion and beauty trends is nothing new. So just imagine the effect that Nicole Kidman can have in this realm.

At the end of July, the star of "Big Little Lies" presented herself in a new light, with short hair, renouncing in a rare event the beautiful long curls she is known for.

While some may have expected her fans to react with disappointment at such a dramatic departure from her signature style, reactions were quite the contrary. "I love your new haircut," "Nice style," "Simply beautiful," were among the comments posted under the picture.

Truth be told, we don't really know if the Hollywood star, who went short for the filming of the series "Roar" for Apple TV+, really cut her hair she may have opted for a wig or another hair trick.

But it didn't take long for the photo to make the famous "pixie" the cut of the moment.

Highly layered, with longer locks at the level of the ears, this short cut offers volume and movement, and allows for a multitude of original possibilities in terms of coloring.

Playing on a blurring of lines between masculine and feminine, it is both chic and casual, combinations which are perfectly on-trend at the moment.

The style icons who have already taken the plunge

Nicole Kidman is of course not the first star to have embraced a short hairstyle, and more precisely the pixie cut, which seems to be winning over more and more followers around the world.

Many are the stars who have, one day or another, been seduced by this hair trend.

Such is the case, for instance, for Anne Hathaway, Katy Perry, Cara Delevingne, Charlize Theron, Rihanna, Halle Berry, Kristen Stewart and Scarlett Johansson, just to name a few. If anyone still thinks that a pixie cut can't be glamorous, these global icons will prove them wrong.

And you don't have to be a Hollywood star to get a pixie cut. In France too the trend has caused a sensation. Léa Seydoux, Cécile de France, Shy'm, and Louise Bourgoin have all sported a short layered look, not unlike that of Nicole Kidman.

And those who are still hesitating can rest assured, the cut is a classic that regularly returns to fashion. In fact, there are no less than 2.3 million mentions of #pixiecut on Instagram, and over 132 million views on TikTok.

If you're not feeling bold enough or you're just not ready there's no doubt you'll have more opportunities to shorten your lengths in time for the fall.
