I think the crimp frizz may have two causes. Aside from suffocation, I strongly believe it can be caused by the hair being too dry.
Before I even knew I had 3a/3b curls, I only used sulphate shampoos that had no silicones in it and my hair was very crimped because of the dryness. Once I started washing my hair with more oils, the crimped frizz went away.
