I don't really have any must haves in terms of brands of products, but I do need certain types of products.

For instance:

A really good detangling conditioner, otherwise combing out my hair is a miserable experience.

A moisturizing leave-in


Of all the types of products listed, I have about 2-4 of each that I know work really well with my hair. None of them are Deva products though. I've never tried that brand.
3B that is no longer CG, but still endeavors to have healthy hair by not using sulfates.
