It makes the hair very dry. Also, though the white powdery stuff disappears from above the hair, a layer of it remains visibly mixed with the hair, almost like fine flakes of dandruff. And no matter how long you brush your hair, these particles remain. Stuck with the bottle now, cannot even return.
For best results, you can use it on day zero, the day you have shampoo so that it starts to absorb oils. You can even use this to add volume or texture to your hair. Only thing is you have to make sure your hair is completely dry before using this. I can easily go 3-4 days without shampoo if I use this. My scalp is really oily and used to get dirty by the evening of washing it. However I will say one thing, that before starting to use this product I tried my best to train my scalp to produce less oils. I washed my hair once every 4-5 days for almost 6 weeks, and that made my scalp produce less oils. Then I started using this product.
