This particular product is an oil that you apply to your hair before taking a shower. It can be used on wet or dry hair, needs to be massaged into the roots, and left on for about an hour or longer if you have time, and then you can wash your hair with shampoo as usual. Although I have oily hair, I didn't notice any weighing down after using it. I also didn't see a tremendous difference in my hair. Maybe it provided a little extra hydration. What I did notice is that it reduced the amount of hair fall that I experienced before using it. In terms of price and quantity, it is probably quite expensive. Especially if you have long hair, it runs out quickly. I'm not sure if I would buy it again
