I'm using JASON natural jojoba oil conditioner after shampoo. I do not have dandruff but I do get itchy scalp, especially in the colder months. I've just started to use it and I like it a lot. I got a 16 oz. bottle at Whole Foods for $9
I've heard cade oil is really good for dry scalps/ dandruff.
I've used the Dandruff control shampoo from Jason and it is really great. I would recommend it and you can get it at Whole Foods.
