This stuff seems to do the job well. I tend to use this after a few days of using dry shampoo and/or Toppik hair fibers to remove all buildup. The only thing is the smell which at first smells like motor oil but it subsides soon after.

Bought this product to help eliminate the excessive buildup caused by winter weather.

I read some reviews about how this product was a gentle version of more harmful, but effective, anti-dandruff products. I used it as directed and noticed that it did alleviate the itching and improved dandruff flakes (but it did not "eliminate them" as promised). The product also severely dried out my (curly) hair. That issue was easily fixed with some deep conditioning, though it did make each time I washed my hair even more of a chore. If your priority is finding an organic, gentle product, this is the one for you. If you're not willing to sacrifice effectiveness, don't buy it.
