The OSiS+ Smooth & Shine Collection combines lightweight conditioning agents, shine‑boosting esters, protective polymers, and nourishing ingredients to smooth frizz, control flyaways, and add glossy shine. The Glow Frizz Control & Shine Serum uses shea butter and polyquaternium polymers to condition and smooth without silicones, while the Sparkler Shine Spray delivers lightweight gloss and frizz control via esters and aerosol carriers. The Flatliner Heat Protection Spray adds heat‑defense with protective polymers and hydrolyzed keratin, while also smoothing and strengthening the hair. Together, these products tame unruly hair, enhance radiance, protect against heat and humidity, and leave hair soft, manageable, and luminous without heaviness.
