Isla Fisher has some of the most recognisable hair in the business, and she - along with those glossy locks - are back, starring in the hilarious and heartfelt new movie, Spa Weekend.

Isla, 50, stars alongside Leslie Mann, Michelle Buteau and Anna Faris, four lifelong friends who take a relaxing vacation to a luxury spa retreat, only for it to be completely derailed by their old pal Mel, played by Isla Fisher. Chaos ensues and if the trailer is anything to go by, it's going to be absolutely hilarious.

Isla's been looking stunning in the run-up to the release of the new movie, and I discovered along the way that her hairstylist, Chad Wood, is a fan of a $40 haircare product that he says is the "perfect foundation for healthy, red carpet–ready hair."

  • Isla Fisher stars in the new comedy movie, Spa Weekend.
  • The 50-year-old's hairstylist revealed he uses the Pro Goddess Leave-In Treatment, $40 / £25 on Isla's long hair.
  • He called it "the perfect foundation for healthy hair."

Styling Isla's hair for the 2026 Vanity Fair Oscar Party, Chad revealed how he achieved her full, glossy looking hairstyle.

After using the Pro Goddess Shampoo and Conditioner, he worked the Pro Goddess Leave-In Treatment through Isla's hair, before blow-drying to create volume. Once dry, Chad "pinned each section, and set the style with a 2-inch curling iron following a round-brush blowout. A light mist of medium-hold hairspray at the roots locked everything in place."

I personally am a big fan of a leave-in treatment, as it's much easier and more convenient to use than a hair mask and can have incredible results - just look at Isla's hair for proof.

The product sounds a brilliant one to keep when on tap for when your hair is particularly stressed, dry or dehydrated. The 5-in-1 styling protection is said to strengthen hair, while also shielding it from heat, humidity and pollution. It also helps with controlling frizz and keeping a style in place, without being too heavy a product - this is one even the finest of hair will find lightweight enough.

It's suggested to apply a dime-sized amount on wet or damp hair before blow-drying or leaving to air dry, running it through the mid-lengths to ends.

What do verified shoppers say about Pro Goddess Leave-In Treatment?

This product has received hundreds of positive reviews on Amazon, with some shoppers calling it "remarkable" and "the best". 

It has overwhelmingly been commented that it's great for fine hair, leaving it soft and manageable without being weighed down or greasy looking, and some commented that it leaves hair looking healthier and smoother.

Other Amazon shoppers wrote that it's more expensive than similar products, but that such a small amount of is used that one tube lasts a long while.

Isla's beauty faves

Isla has also been vocal in her love of the IT Cosmetics iconic CC+ Foundation and IT Cosmetics Confidence in a cream. The A-lister, who is the newest face of the brand, revealed that it has been her "go-to foundation with the same incredible formula I’ve trusted for years."

Wearing the CC+ Cream in Light Medium, the Australian actress told People magazine that she's "basically the laziest person in beauty that you'll ever meet" and uses the cream and foundation as a few of her only beauty products. " I get out of the shower, I put my hair in a bun, and I put on my IT Cosmetics."

We love Isla's laidback approach to beauty - a woman after our own heart!

Isla's fashion faves

Isla's love of an affordable fashion brand is such a breath of fresh air. She's was snapped in a series of candid photos with her Spa Weekend colleagues (above) wearing the ME+EM Fit and Flare Maxi Dress, a cotton poplin dress in a dark, olive green. 

Earlier in the year, Isla's wore the Rixo Abi Chiffon Maxi Dress to a Hollywood wedding in Italy, packing the gorgeous Farm Rio Lemon Birds Dress in her suitcase too.
