I love As I Am for my hair (the length of it) but it causes serious buildup on my scalp. Really bad dry scalp too. I shudder just thinking about it. I love Trader joe's tea tree tingle as a co-wash. No buildup and it has moisturizing oils that are also cleansing. Also I like to low poo once a week with one of the Shea Moisture low poos. (I own two but I'm sure I'd love the third one as well.) Haven't had any buildup since I switched.
