I don't understand.....why a non foaming shampoo? How often do you wash your hair...or maybe, if you color your hair it is over processed, maybe it is dry from lack of natural oils....just thinking out loud here......have you tried an oil treatment - about an hour before shampooing rub in some coconut oil......my old profession of hair dresser is peaking out here.....I always message my scalp vigorously before shampooing...just to stimulate blood flow and natural oils....but I don't shampoo my hair daily.....every third day...other days I cover with one of those old fashioned shower caps before bathing....don't know what WEN is...will have to check it out.....
