Sam McKnight's new Cool Girl Body Plumping & Volumising Cream (£29) is a hybrid formula designed to create fuller-looking hair while strengthening strands over time, according to the brand. Unlike traditional volumisers, it targets weakened hair fibres that struggle to hold shape, offering a more lasting solution for flat hair.
What Makes Cool Girl Body Different?
The brand says hair loses volume not just because of wrong styling products, but because the hair fibre itself becomes weakened by heat styling, colouring, environmental damage and general life. When hair is compromised, it struggles to hold shape and elasticity, causing freshly blow-dried roots to flatten throughout the day.
Cool Girl Body uses a cocktail of ingredients to plump individual strands, create separation between hairs for fuller-looking volume, and provide flexible hold without stiffness. It also contains conditioning and strengthening ingredients for resilience, plus heat and humidity protection.
The Science Behind the Formula
Key ingredients include Voluminis™, which increases the density of individual strands and helps push hairs away from one another, creating the illusion of fuller hair. Biostyle CGP™ is a sculpting polymer providing lift at the roots and helping hair maintain shape even in humidity. The formula also features Yerbaluxe® Crown, a conditioning ingredient to strengthen stressed fibres and improve elasticity, plus SymHair Thermo™, offering heat protection up to 230 degrees and acting as a humidity shield.
Review: Subtle Volume, No Heavy Feeling
In a test, the product had a silky, thick consistency that didn't leave hair greasy or weighed down. Using about a 10p-sized amount, the writer noticed strands felt thicker after drying. The volume was subtle rather than dramatic, but with potential to build using the right tools, such as a hot styling brush. Despite the added thickness, hair didn't feel heavy or as though it had extra product in it.
The product focuses on creating conditions for fuller-looking hair while supporting hair health, rather than masking the issue with heavy styling agents. For those with naturally flat hair, it offers a more thoughtful approach to volume.
