CoileenCyclomethicone
What it is
A lightweight, volatile silicone that evaporates at body temperature. It is used in hair sprays, serums, and leave-in products to provide a temporary silky feel without heavy buildup.
Why it matters for curly hair
While cyclomethicone evaporates more readily than heavier silicones, it still coats the hair temporarily and can contribute to buildup when used in combination with other silicones. The silky feel it creates is often mistaken for moisture, but it provides no actual hydration to the hair shaft.
