    Hello! I’m interested in making a homemade deep conditioner. I’ve seen in most cosmetic deep conditioners, they use cetrimonium chloride and behentrimonium chloride. I wanted to know if makes sense use those two as well as cetrimonium bromide and Behentrimonium Methosulfate 25(btms25) in the same formula but at low concentrations? Would they clash? Just curious. Thank you in advance.

    Yes, they would clash. They will all compete for the same damaged protein sites on the hair. So, on some level it is all just redundant. Most of the conditioning ingredients will just wash down the drain. 

    It’s a bit like instead of just putting sugar in your tea, you put sugar, honey, agave, and coconut sugar. Both will be sweet. It’s just that one option requires you to have a lot more ingredients in your pantry without much benefit.
