I just saw that I had replies!
The few things I've heard on another site was to avoid apple cider vinegar, and any product with rosemary in it.
I tried coconut oil and although it didn't affect the gray, it made my hair "snappy." I don't think my hair likes protein (or things that encourage protein retention) much.
Other than that, I've been using aloe vera gel and a tresseme curl mousse and they've both been fine. I occasionally use a purple shampoo, but not often and so far, everything is fine!
Closet wavy...trying to decide if I want to come out.
