Widely incorporated into various hair products, silicones form a film over the hair shaft, reducing friction, preventing moisture loss, and enhancing shine. However, concerns regarding product buildup from water-insoluble silicones and the environmental implications of certain cyclic silicones have emerged. Recent advancements in silicone technology, including water-dispersible and nano-encapsulated systems, aim to mitigate these issues while preserving the benefits of enhanced hair texture and protection against thermal and chemical damage.</p><p><strong>Summary: </strong>This article provides a comprehensive review of the classification, advantages, and controversies surrounding silicones in hair care. It emphasizes practical guidance for selecting appropriate products tailored to individual hair types and the importance of preventing excessive buildup. The discussion highlights the need for education on the benefits and proper use of silicones, addressing common misconceptions. Ultimately, while silicones offer significant advantages in hair care, a balanced approach combining efficacy with environmental responsibility is essential for their continued use as a viable solution in the industry.</p><p><strong>Key messages: </strong>Silicones provide numerous advantages, including enhanced hair texture, improved appearance, and increased moisture retention in hair care formulations.
