Smoothing Agents

Smoothing agents appear as lightweight serums, creams, or silicone-based fluids with a silky texture. They work by filling in surface irregularities, reducing roughness, and enhancing softness. They are ideal for hair serums, primers, and anti-frizz treatments. 

Popular INCI ingredients in this segment include Dimethicone, Cyclopentasiloxane, and Hydrolyzed Silk. Trends show these agents are now paired with botanical extracts or hydration-boosting ingredients. Some silicones may have regulatory restrictions in rinse-off products.
