It is a high-charge-density conditioning agent widely used in both rinse-off and leave-in haircare formulations, valued for its ability to deliver substantive conditioning, enhanced shine, and improved wet and dry combability — particularly in formulas where a stronger conditioning effect is needed than lighter polymers can provide.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIn a detangler mist, PQ-7 functions as a primary co-conditioning active, contributing to the slip, smoothness, and anti-frizz performance that make a leave-in treatment effective across a range of hair types, including coarser or more porous hair that requires a more substantive conditioning response.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHow It Works\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003ePQ-7's high cationic charge density allows it to bind strongly and rapidly to the negatively charged surface of the hair shaft, with preferential deposition in areas of cuticle damage where electrostatic attraction is greatest. This targeted deposition lays the cuticle flat, reduces inter-fiber friction, and forms a lightweight, flexible conditioning film that improves manageability in both wet and dry states. Unlike some heavier cationic conditioners, PQ-7 is compatible with a broader range of anionic and nonionic ingredients and is well-suited to aqueous spray formulations where film-forming efficiency at low use levels is important.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eFor external use only.
