WHY HAIR FALLS FLAT

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.

Most volumisers focus on styling. But 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.

Cool Girl Body helps strengthen the hair fibre, increasing its elasticity and resilience, creating structural support that allows volume and body to last longer.

COOL GIRL BODY DIFFERENCE

Sam’s breakthrough volumising formula designed to instantly plump and fortify every strand - helping support hair’s strength and resilience needed to hold volume for longer.

BIGGER
Every strand 12% thicker in one use. 100% saw instantly more body and fuller hair.

STRONGER
More than twice as strong hair fibre to help style last longer. 85% agreed hair stayed full even in humidity.

BOLDER
100% felt more confident about their hair. 85% agreed hair has never looked and felt better - fuller, thicker and healthier from first use.

Cool Girl Body is suitable for all hair, but especially effective on fine, thinning, fragile, colour-treated or damaged hair. Ideal for flat hair that loses body within the hours.

Infused with Sam’s signature botanical fine fragrance.

*Benefits reported in consumer testing (n=[41). **Clinical study measuring hair fibre diameter after 1 and 6 uses.

THE SCIENCE OF LASTING VOLUME

Stronger hair holds volume and style for longer because the hair fibre has better elasticity, structure and resistance to collapse, from humidity, gravity or daily stress.

Cool Girl Body build lasting volume in three ways:

VOLUMINIS™
Plumps every strand increasing density and pushes hair fibres apart for all-over fullness and body.

BIOSTYLE CGP
Lifts from the roots, holds its shape and protects hair volume against humidity,

YERBALUXE® CROWN
Fortifies and transforms weak strands, increasing resilience and elasticity for glossy, strong hair that holds volume for longer.

WHY IT'S IN SAM'S KIT

“It’s the product I wish I’d had 40 years ago, because extensive, frequent styling can take a heavy toll on models’ hair.
I wanted to create a volumiser that made achieving your desired look effortless. A natural looking fullness that looks and feels healthy, smooth and soft - never stiff or overloaded.
The kind of volume that brings hair back to life.”

- Sam McKnight

Cool Girl Body

Is Cool Girl Body suitable for fine, fragile hair?

Yes. Cool Girl Body was developed specifically for hair that lacks body, including fine, fragile and thinning hair. Its lightweight formula fortifies every strand while providing lift, humidity protection and heat defence, helping hair feel stronger without weighing it down.

Can Cool Girl Body be used on coloured, damaged or chemically treated hair?

Absolutely. Colour-treated and chemically processed hair often loses strength, making it more prone to collapse and breakage. Cool Girl Body reinforces the hair fibre while protecting against heat and humidity, making it an ideal styling product for hair that's been coloured, highlighted or chemically treated.

Why does hair get finer with age or hormonal change?

As oestrogen declines, hair follicles can gradually shrink, producing finer strands with less structural strength. Hair also becomes more susceptible to breakage, while environmental factors such as UV exposure, pollution, heat styling and chemical treatments further weaken the hair fibre. The result is hair that feels thinner, loses volume more easily and struggles to hold its style.

What’s the difference between Cool Girl Body and other Cool Girl volumisers?

Cool Girl Texture Mist, Superlift and Volume Foam are your go-to stylers for instant volume and lift. Cool Girl Body works as a foundation step - it strengthens and thickens the fibre itself, helping hair hold volume for longer between styles. Use it on its own for thicker hair and fuller body, or finish with Cool Girl Texture Mist dry volumiser for an extra volume and texture boost.

How do I use Cool Girl Body?

Apply Cool Girl Body to freshly washed, towel-dried hair, smoothing through roots, all the way down to the ends. Blow-dry for maximum lift and body, or leave to dry naturally for effortless volume. It provides heat, humidity and UV protection while helping styles last longer, making it an easy everyday step whenever you want fuller, healthier-looking hair.
