I'm new to this too and still experimenting. I have found that I get the best results by tweeking my rountine... depending on how my hair feels any given day. My hair is 2a fine/medium texture and can get easily OC'd. When that happens I use a clarifying shampoo and a lighter weight moisturizing conditioner.
Being a 2a I just can't do the co wash very often...or my hair is limp and any wave I do have is gone. I'm sure there are 2a's on the board who can co wash more often.
I think the CG method is all about finding what works for you.
I have had a few weird hair days when I tried something that didn't work for me but I don't sweat it. I just do something different the next day!
