I’d say Polyquaternium-37. Although Dimethicone Copolyol or dimethicone would be even better.

@Perry44 Could I ask why you believe Polyquaternium-37 would be better than BTMS for a leave-on application? Is there any benefit to using both? Thank you!

This is an old discussion! But I say PQ-37 is better for leave in because you need to use less of it to get a reasonable effect. You could use 0.2% of PQ-37 that would give you the same effect as say 2% BTMS. So, this would result in hair that feels less weighed down.

@Perry44 Thank you so much! There aren’t many discussions on the forum about this ingredient. I didn’t realize it was so effective at such a low level; I was trialing 0.5% PQ-37 with 0.5% active BTMS and 1% dimethicone for a leave-in.
If I omit the BTMS, do you think the PQ-37 and some cetearyl alcohol would be able to keep the dimethicone bonded? The only other components are preservative, fragrance, and HEC.
