Polyquaternium-11

Polyquaternium-11 is a cationic polymer - a long molecule with a positive charge. This allows it to cling to hair and form a thin, flexible film on its surface.

It smooths the strands, reduces static and makes styling easier, while in a scalp serum it helps distribute caring ingredients and keeps hair from looking weighed down. You will find it in our hair growth stimulating scalp serum.
