It has more to do with your texture and porosity than hair type.
I considered myself, and still do at times, a wavy for the first year I was on here (I've been on since July 2007 but didn't join till much later). I've used shampoo bars a couple times to experiment but other than that have only used conditioner to wash since July 2007.
My hair is fine and medium porosity. I only co-wash once a week or less. If your hair is fine, try cutting back on how often you condition, water wash instead, before adding in a low poo.
