I've found, for the most part, that when a shampoo tries to do something more than just clean and create lubricity for washing (i.e. add gloss, wash and wax etc) they create far less suds. I bought a Megs wash and wax and had to use 3x more than recommended to get the amount of suds I thought was safe.
Mr. Pink from CG is a great wash either way and I highly recommend it.
