I think we would need to know what products you are using that cause the build up.
Are you doing the no sulfate no cone routine? If you are using cones /beeswax/ for example they are not easily removed without sulfates.
I have not had any build up with my routine.
I'm sure more experienced curlies can help you if you let us know what you are using.
