This conditioner has some fantastic ingredients and really would help to aid thickening. The problem I found with it was that it does not easily slide through the hair and does not feel like a conditioner, more of a rinse. I have tried the partner shampoo to it, which I absolutely love, so out of the two I will definitely be buying the shampoo again but probably not the conditioner. If they were to add a 'slicking' agent to allow you to detangle the hair much more easily I would also buy the conditioner as well because the actual ingredients DO aid hair health, growth and thickening.
