The Nexxus Prep & Protect Heat Defense Spray is a polymer-based thermal shield. It utilizes a blend of silicones and hydrolyzed proteins to provide a physical barrier against 450°F thermal stress while managing the appearance of the hair cuticle.
Formulation Analysis
This formula relies on VP/VA Copolymer and Polyquaternium-11 to form a heat-resistant film. Hydrolyzed Elastin and Hydrolyzed Keratin are incorporated to condition the hair fiber. Amodimethicone provides targeted conditioning to specific areas of the hair without the heavy buildup often associated with standard silicones.
Attributes and Observations
- High-Temperature Resistance: Suitable for styling up to 450°F.
- Protein Infusion: Conditions the hair cortex and surface.
- Lightweight Finish: Suitable for fine to medium hair types.
- Considerations: Contains Alcohol Denat.; avoid over-saturation at the roots.
To maintain internal moisture levels, supplementing the routine with a lipid-rich deep conditioning treatment is suggested.
