I moved to a different city, and either the change in water or climate caused me to have TERRIBLE dandruff. I went to the dermatologist and she prescribed me a steroid shampoo, that didn't work. I tried T-gel, men's head and shoulders, medicated selsun blue, nizoral, home remedies such as Apple cider vinegar, avocado, baking soda, you name it. Nothing worked for me, I had to deal with the dandruff for months and tried multiple things with no solution. I found this and it had good reviews so I figured I would try it. IT ACTUALLY WORKS, not only was my dandruff gone after only a couple of uses but my hair is softer and shinier, and is growing faster(I think from the olive oil conditioner). I've been trying to grow out my hair and it sort of stops growing at a certain point, but its getting SO long and looks and feels better than ever since I've been using this shampoo/conditioner. I will continue to use this product for dandruff control and because it makes my hair look amazing!!!
