What are some brands of shampoo/conditioners that wont cause dandruff/dry scalp?

Moisturizing shampoos and conditioner are known to leave build up on the scalp and cause dandruff and even dryer skin in some cases. The best thing to do is keep trying out different shampoos until you find the right one for your hair type and skin. Every shampoo will have different results for different people. Shampoos with fragrance in them irritate my scalp and no matter what the brand is or what they claim to help if it has fragrance in it (which 99% of brands do) It makes my scalp dry, itchy and flaky. I use Dove or Aveno in my hair and once or twice a month I use a clarifying shampoo that helps remove build up from products. You can make a clarifying rinse by adding a few teaspoons of vinegar in some luke warm water using that on your scalp followed by a cold water rinse.
