I found this to be a really effective shampoo. I purchased it recently because I had heard good things about this brand. I have really oily hair and it is worse in the summer time. It takes a good shampoo to get all the dirt and oil out of my hair. This shampoo was able to accomplish that with only one application. It truly gave my hair a deep clean and got all the oil out of it. It also kept it looking clean throughout the entire day. I would definitely recommend this shampoo to anyone with oily hair. It did a great job getting mine clean. Effectiveness I found it to be really effective at getting all the oil out of my hair. I have oily hair and it made mine look very clean. It stayed clean for about 24 hours after using this shampoo. I had to wash it each morning with it to keep it looking clean. Scent I think that the scent is good. It is not very strong so it does not stay in your hair as long. However, it does leave it smelling nice for a short time.
