POLYQUATERNIUM-15
Safety grade: B
This is a synthetic polymer (a chain of molecules) that's positively charged, similar to how static cling works. It's designed to reduce frizz and flyaways by neutralizing the negative charges that make hair stand on end.
It reduces static electricity in hair and skincare products while creating a lightweight, invisible protective film that smooths the hair surface and improves texture.
Graded using: COSING.
