Even with tonnes of hair tools such as hot brushes and curling wands at my disposal as a beauty editor, I actually can’t stand my hair looking too “done”. Don’t get me wrong, I love a bouncy blow-dry when the occasion calls for it. But day-to-day, I like my hair to look effortless and undone, like I just so happened to have rolled out of bed with perfectly dishevelled loose waves.
So it’s probably unsurprising that Sienna Miller, Alexa Chung and Kate Moss are amongst some of my hair icons for their perfectly undone hairstyling and piece-y waves. Of course, their hair is expertly crafted by top hair stylists, but it just so happens that they’re all fans of one particular texturising spray.

Cool Girl Barely There Texture Mist
Pros
- Adds volume, texture and lasting hold
- Great for fine hair types
- Smells amazing
- Loved by celebrities
Cons
- More expensive than most texturising sprays, but worth it
Cool Girl Barely There Texture Mist is one of those products that is exactly what it says it is on the can. Created by legendary hairstylist Sam McKnight MBE (who has worked on everyone from Princess Diana to Kate Moss and Sienna Miller), this texturising mist adds the perfect amount of grit to lengths, boosting volume and texture even in the finest of hair. McKnight was inspired by the effortless looks he’s created on Kate Moss, and designed this product with her in mind to help us create the same undone looks at home.
In the above video, McKnight uses it on Sienna Miller, flipping her hair upside down and misting through for effortlessly texturised lengths. Alexa Chung also counts herself as a fan, having previously called it “a gig in a can” for her signature dishevelled waves. It’s cool-girl hair in a bottle.

I’ve been using this product for years and can also attest to its brilliance. If I ever find my curls or waves are looking too polished, I like to spritz a little through my lengths and use my fingers to dishevel as I have above. It helps keep curls and waves looking undone whilst enhancing texture and giving root lift when sprayed around the crown. It’s also one of the best-smelling hair products I’ve tried. In fact, I’ve had compliments on the scent alone.
Whilst it’s not strictly a hairspray, it does offer lightweight hold to styles and brushes out easily at the end of the day—zero crunchiness here. Honestly, if you only invest in one hair product, make it this one. It also comes in a handy handbag-sized travel bottle, which is perfect for top-ups on the go. McKnight, thank you for your service.
