WHAT’S INSIDE

Cool Girl Body Plumping & Volumising Cream

A hybrid styling-with-care leave-in that instantly plumps and fortifies every strand, so hair holds its shape and body for longer. Leaves hair soft, glossy, and full of movement, with heat protection to 230°C and built-in humidity and frizz defence..

Cool Girl Barely There Texture Mist

Sam’s iconic go-to volumising texturiser — the one Vogue calls “Sam in a can.” Spritz in, mess it up, done. Lightweight and brushable, it amplifies volume and creates his signature ‘done, undone’ texture while keeping hair soft, touchable and easy to restyle. A multi-award-winning styling essential and one of WWD’s Greatest Hair Products of All Time.

Why You'll Love it

Expertly formulated for all hair types and textures.
Leave hair transformed yet touchably soft and shiny, never stiff.
Infused with Sam’s signature fine fragrance of Frankincense, Juniper Wood and Water Lily, reminiscent of his garden in the rain and created in collaboration with Perfumer H.
Fully recyclable packaging made from at least 30% post-consumer recycled plastic

How To Use

Start by smoothing Cool Girl Body Cream through clean, towel-dried hair.
Air-dry or blow-dry.
Once dry, spritz the Barely There Texture Mist through hair to amplify volume and add texture. Use between washes to bring volume back.

Why The Foundation Matters

Volume starts with the hair itself. When hair becomes finer, weaker or more fragile, it has less structure to hold its shape - and your volume. That’s where Cool Girl Body comes in. This hybrid styling-with-care cream plumps and fortifies every strand, helping to strengthen the hair fibre, improve resilience and build a thicker, fuller-looking foundation for your style. So you’re not just styling volume. You’re building the hair foundation that helps it last.

Why Won't My Hair Hold Volume?

For many people, the frustration isn't just getting volume - it's keeping it. Hair that looks full when styled can fall flat within hours, losing lift and body. When your hair is fine, thinning, fragile, colour-treated or damaged, volume drops fast because the hair fibre itself lacks strength and has lost its ability to hold shape. As that happens, lift collapses. Body disappears. Hair falls flat.

Question I get asked: how do you make volume actually last?

Here’s what you need to know.

COOL GIRL RECOGNISED AS "THE GREATEST HAIR PRODUCT OF ALL TIME"

Since my Cool Girl Barely-There Texture Mist launched in 2017, it has become a cult, award-winning, and best-selling product - most recently, it was recognised by WWD as one of the "Greatest Products of All Time" and named Best Hairspray at the Sheerluxe Beauty Icons 2025. It's even been labelled "Sam-in-a-can" by Vogue because of its ability to instantly transform hair into my signature effortlessly undone, artfully mussed-up voluminous hair look. For inspiration, think my long-term collaborator and friend, Kate Moss, who effortlessly rocks this look at any event, in any outfit. It's always a good look.
