If it ain't broke, don't fix itIf your hair and scalp is doing so well until now, I would not change anything and keep on using the moisturising shampoos. Your hair has never been dry again and if it's getting longer and longer, it obviously loves what you do. I've used co-wash cleansers off and on. The ones from As I Am and Boucléme are nice, but I like to see them as a refreshment in between. So something I would use in summertime if I want to wet my hair scalp daily or for very sweaty workouts until the actual hair wash.
My regimen is good, but I think that it could be great. I have a faster than average growth rate, and I know that I'm not retaining all the length that I could be. I'm greedy for them inches ! And I want to make those changes now at this length so that I have my regimen down pat when WL comes.
