I tangle like crazy and I use my Mebco comb and finger detangle at least 5 times, often more, to get rid of all the shed hairs that are caught up. I find I can detangle much easier with the S&C method. I think it's because conditioner penetrates longer.
I do the flip over hair rinse in the shower and have to hold my hair very carefully to not tangle when I right myself - that's after combing out "all" the tangles.
I can apply my LI and products upside down and no problems when I right myself with tangles. It seems everything is stuck back together by that point.
I like a base product with slip too. I think it's one of the reasons I loved CK so much for so long. It was my base layer and had so much slip.
So if those that tangle a lot prefer slip and those that don't prefer grab, what characteristic(s) makes one tangle more? Maybe that's common denominator.
I think RCC's hair and mine are pretty much opposite in texture and porosity yet we both tangle and get fairy knots.
