Spectral DNC / DNC L vs. PG Issue?

[fallout2rocks]

Does anyone know if Spectral DNC and DNC-L conflict with PG on scalp? I seem to recall reading somewhere that PG interferes with DNC delivery systems and it's bad to apply both at the same time? However, I've exhausted the search function on this forum and googled this question with no results.

Help? :dunno:
