TRUSS Fluid Fix – Long-Lasting Curl Definition & Heat Protectant Spray
Root lift tends to collapse first, and this leave-in spray is aimed squarely at that problem. Fluid Fix layers definition at the roots and holds curl shape for up to 24 hours, drying fast enough that you can keep working without waiting around. Curls stay sculpted rather than stiff.
The formula dries down non-greasy and forms a protective layer around the cuticle. That layer does three jobs at once: thermal protection for the hair's natural structure and elasticity during heat styling, frizz control that keeps flyaways down through the day, and colour-safe cover that helps prevent fade when hot tools are involved.
What it does
- Holds curl definition and root volume for up to 24 hours
- Dries fast with a non-greasy finish
- Protects hair structure and elasticity through curling irons, flat irons and dryers
- Controls frizz and flyaways across the day
- Helps prevent colour fade during hot-tool styling
How to use it
Spray evenly over damp or dry hair, then comb through so it is distributed properly. Shape curls and waves with a curling iron or dryer, then mist lightly to set. Reapply through the day to refresh texture, sharpen definition or lift the roots again.
Suits all hair types from fine to thick, and works for defined curls, soft waves and added root lift.

Application tips
Spray it in before the heat, not after. Damp hair, sectioned, a few passes at the roots where the lift matters and a lighter coat down the length.
Comb it through to spread it, then dry as usual, with a diffuser for curls or a brush if you are smoothing. It dries fast, so keep moving. On dry hair it works as a root refresher, though the hold does not last as long.
Results
Root volume survives the day instead of dropping by lunchtime, and curl shape stays where you set it for a full 24 hours.
The finish is dry and sculpted rather than stiff or tacky, and nothing greasy is left on the hands. Flyaways stay down. Under a flat iron or a wand it puts a layer between the heat and the strand, which is worth having on coloured hair.
