Great Product for Hard Water
Style: Shampoo
We have hard water and just after a week of using this I can already tell a difference, not only that but I've been using it on my upper arms, shoulders and neck and my keratosis pilaris is clearing up and my skin is smooth. Great product, happy I found it.

Not bad... but not great either.
Style: Shampoo
Let me make one thing perfectly clear at the get go: I am spoiled when it comes to shampoo & conditioners. My wife has super fine hair so she buys the expensive Biolage stuff and I use it too because I only need a tiny little dollop for my hair. So I know how my hair feels after pricey shampoo and this.. well.. this isn't it. Mind you, it's not bad. If I wasn't so used to to Biolage, I'm sure this would feel fine. However, this definitely made my hair feel like I had just washed with something like Salon Selectives. It just felt different. Maybe it's the aloe in there but my hair just didn't feel as nice as usual when I tried it. So, if you're used to low-to-mid range store bought shampoos, you might like this a lot. Jeez that sounds pretentious! LOL, sorry! Again, it's not like my hair fell out or anything weird, but I've had the good stuff and I'll stick with the good stuff. I'm still giving this 4 stars out of fairness for a perfectly fine shampoo. It still lathered up nicely and my hair was perfectly clean, but just don't expect a high-end feel.
