Silicone is a common ingredient in hair products that helps smooth, add shine, and reduce frizz by coating the hair strands. It creates a protective layer, locking in moisture and making hair feel soft. However, it can also build up over time, weighing down hair or making it look greasy if not washed properly. For best results, use a clarifying shampoo occasionally to remove any silicone buildup.
