Sounds over conditioned to me. I don't know what your hair properties are but I would suggest a clarifying wash & some protein. The SN coconut has minute amts of protein but nothing spectacular. OC'd hair is exactly what you describe & you'd benefit from a gentle shampoo. If you have fine hair, look at adding in some protein to your routine too. Hair properties are much more important than curl type & I can't give much advice without knowing them (I'm on the app so if they're in your signature I can't see them).
