It's tough to say. I've only tried one product from Oyin, but I love it! (the honey hemp condish) I have quite a few HGs from CJ, including the gentle cleansing shampoo, argan+olive oil conditioner, CCCCL, and rehab. If I had to suggest one product though, that is awesome for all hair types and properties, it would have to be the CJ rehab. That stuff is amazing!
