A friend of mine had ordered me the neutrogena T/Gel anti-dandruff shampoo for Greasy Hair, and from all the products that I had tried this is by far the most product that controlled my Oily Hair and dandruff. I used to have to wash my hair mostly everyday due to my hair becoming so oily but using this product i realized that now i wash my hair mostly every 3-4 days . The results did not show up from the first few washes but after a while i started seeing a huge difference. Will definitely buy another bottle of this amazing shampoo :)
