Curly Girl Method Status
Cyclopentasiloxane is a non-water-soluble silicone. The Curly Girl Method classifies it as Warning because it coats the hair shaft and cannot be fully removed with sulfate-free cleansers, leading to product buildup over time. If you follow the CG Method strictly, avoid products containing Cyclopentasiloxane. Look for water-soluble silicone alternatives instead.
