Meet the newest addition to the FORMULA 18 lineup, Medium Hold Finishing Spray. Designed to deliver flexible control with natural movement, this finishing spray helps lock in the style while maintaining softness, shine, and touchable performance.
Perfect for everyday styling, polished finishes, and long lasting hold without stiffness, plus incredible heat protection to support the hair through every style.
FORMULA 18 Plant Based Reinforcement Additive is engineered to support the structural integrity of the hair during chemical and styling services through a blend of plant derived performance ingredients. Designed to work within the hair fiber, the additive helps maintain elasticity, moisture balance, and overall resilience while the hair undergoes stress from processing and heat exposure.
Powered by ingredients such as Pea Peptides, Tamarind Extract, and Resurrection Plant, the formula helps reinforce weakened areas of the hair while supporting hydration retention and improved flexibility. Its cationic technology allows targeted adhesion to negatively charged, compromised sections of the hair shaft, helping optimize conditioning, improve surface alignment, and support more consistent color uptake and retention.
By improving the way the hair responds during services, the additive helps create stronger, smoother, and more reliable results without compromising movement or manageability.
