The Cool Girl Texturising Mist has received plenty of five-star reviews on Sephora, and one major reason Cat's clearly obsessed is its knack for making flat hair look thicker and more voluminous. Shoppers are told to spritz it through the crown, mid-lengths and tips.
Another contender worth considering is the Living Proof Full Dry Volume and Texture Spray. Coming in at £31 for a 238ml bottle, this volumising wonder pledges to give dry hair that effortless, lived-in vibe.
Cool Girl Texturising Mist

Praised by Cat Deeley, this much-loved hair mist is designed to easily create tousled, textured styles.
Several customers have mentioned boosted volume without any rigid stiffness. Beauty enthusiasts can also get a workable hold with the Cool Girl Texturising Mist, which is free from sulphates.
Beauty fans have raved about the fragrance of this product, with one devotee commenting: "Love this. It's very different to other hair spray, no residue, no stickiness and has the iconic scent I love. Spray on once dry from the roots and you will see a noticeable difference in volume."
For those seeking enhanced volume and texture, the Lee Stafford 3-In-1 Texturising Spray offers a quick hair revival. Stocked at Boots, a 200ml size is priced at an affordable £9.50.
Returning to feedback on the Cool Girl Mist, one thrilled buyer said: "This literally doubles the volume of my hair, and turns waves into big bouncy waves. It also smells gorgeous. On my third bottle! Top it off with some hairspray and the curl/wave will have moderate hold too."
An award-winner, the Hair By Sam McKnight spray reportedly works across all hair varieties and types, though it hasn't won universal acclaim. One reviewer noted: "Effect does not last long, there is little hold after a few minutes. Definitely not worth buying."
Conversely, another satisfied user enthused: "This is the best product I know of to give fine hair a boost of volume without stiffness or stickiness. Can't do without it. It smells fabulous too."
