Have you tried a HOT oil pre-poo

If I know its going to be a tough detangle session I

Warm some EVOO or EVCO up ,and apply to my hair section by section, while doing a light finger detangle and a nice sclap massage( helps with dry itchy sclap)

I do 4 loose braid and put on a plastic cap for 30min., if you do it overnight even better.

Then I hop in the shower and wash my hair in sections

I let the warm water run thur my hair knocking out some of the detangles, it makes things much easier.
