Effective, but a bit small
I bought this to help purify my hair. I live in a place that has very hard water that builds up on my hair, as well as having oily hair and using a lot of dry shampoo. This exfoliating shampoo does a great job of getting that buildup off of my hair and scalp. The shampoo was smaller than I was expecting based on the cost. One other thing is that this shampoo has a very thick consistency - you're supposed to use water to "activate" it but I have a hard time knowing if I've done that properly or am using way more product than I should.

Thanks for sharing your experience! If you have any difficulty spreading the product through the hair, you might consider double cleansing by shampooing with your regular shampoo before cleansing and exfoliating with Submarine. This should help to remove excess oil and build-up, and allow Submarine to more thoroughly cleanse the hair and scalp. We hope this helps!
