It does make some people curlier. I have naturally weak waves and pre CG I never styled my hair at all. I committed the cardinal sins of brushing dry hair and getting bad hair cuts!! I would always get my hair thinned.

Now my hair at least looks a little wavy. Not much different without product though.
