Giovanni shampoos, conditioners, and even styling products are amazing. If you're looking for more natural, health and eco-conscious beauty products, try theirs; They've (as yet) been the most reliable brand I've found in hair care. I've used other brands (well known and otherwise/ cheaper and more expensive) and always come back to Giovanni for performance, and the assurance that if I use one of their products, I'll at LEAST really like it, if not be in love with it. They must test these products out to excess, because every single one I've tried works, and works really well. And one major bonus to their products, in my opinion, is that they ALWAYS smell like natural botanicals, not like chemicals. They never make my sensitive nose react to the fragrance. The scents are never really strong, but they're there, and they're pleasant.If you want something that will really clean your hair and scalp, this shampoo is worth a shot. If you tend to be a little on the oily side, or like me, believe that you should let your hair get a little oily before you wash it, this shampoo may be the one for you. A lot of the natural shampoos have a difficult time competing with SLS products in terms of getting rid of oil and really making your hair and scalp feel clean. That's harder to do when you aren't using sulfates. This shampoo, however, does a great job. It'll really clean your hair, but doesn't go overboard. Not to mention the shine you'll have. It looks like I used a shine serum when I didn't!Personally, I prefer the Tea Tree shampoo they make. That one is number one for me in terms of cleansing. In my opinion, it cleanses even better, and allows me to wait just a little longer before washing. (I like to let the natural oils from my scalp moisturize and protect my hair.) This one is just a little less stripping, which is good if you're washing more often. I would say this one is middle ground between the Tea Tree, which is really clarifying/cleansing, and the 50/50, which is more moisturizing. If you haven't tried their products, give them a shot. For myself, I've been able to test all of their shampoos (except the Root 66, so far) and I like them all!
