I received this sample with another order. I have used apple cider vinegar on my hair before in the shower, but never as a leave in treatment. Smell is neither pleasant nor unpleasant and didn't linger too long after my hair dried. As for it's effectiveness as a leave in treatment, I didn't feel that it did anything spectacular for my hair vs no products at all.

This is a sample that I had - I can’t recall where from unfortunately. I thought this was kind of a fad thing and I didn’t expect this apple cider product to smell great however it was a fainter smell than I expected and disbursed throughout the hair, the smell isn’t too noticeable and it fades. My hair feels better after using it, the ends of my hair felt a little lighter and more healthy.
