I've been using the C&S Leave-in since November I think. I like it because it's cheap, widely available, and it gets the job done. I have also been able to use it by itself without styling products over it, with good results. I don't love the smell, but it doesn't linger in my hair.

I wash 1-2 times per month with a sulfate-free cleanser (Curlicious Curls or Jessicurl HCC), otherwise I just wash with Deva No Poo.
