New Wash is quite different from WEN. Neither has detergent and neither foam, but the similarity ends there. The biggest difference is that Wen contains silicone that can build up to make hair lank and clog follicles. New Wash does not.
Since WEN gained national recognition, many companies have jumped on the “co-wash” bandwagon. The term originated in the curly community, and basically means rinsing with conditioner instead of shampooing.
The term co-wash is in and of itself confusing to consumers (maybe that is the point): First, no one should be cleansing hair with strictly conditioning products because there is no cleansing happening; they will inevitably build up in a few weeks and make hair feel heavy and greasy. Second, it’s marketed to certain demographics – curly or wavy hair – but why? Third, when most people think about a co-wash product they assume it’s good for them, meaning no harmful or harsh ingredients – another misconception.
Most co-wash products on the market still contain some kind of surfactant.
Surfactants = detergent. Detergent = problems.
