I have 2 tons of thick, wavy hair that is somewhat coarse and tends to be dry unless I condition the crap out of it. 2 summers ago it was shoulder length and I wore it curly all the time. I would mix together Garnier Wonder Waves mousse and Tresemme Flawless Curls cream in my hand, scrunch that into my hair, then while it was still wet I sprayed some Garnier Anti-Frizz hairspray all over. It was soft and bouncy and shiny - never crunchy or frizzy. And now I'm starting to wonder why I'm hanging onto my long hair because it is an absolute mess unless I heat style it.
Also, as an aside, I found that my natural wave/curls looked better when I combed my hair in the shower with the conditioner still in it, then again right after I rinsed it out. That was it. Once I was out of the shower I didn't touch it with a comb or brush if I wanted to wear it curly. I still do this to keep my hair from tangling but now it doesn't do anything for me aesthetically.
