This of course has been branded to be environmental friendly. Also, it is wallet friendly; both last a long time. I only rub the shampoo in my wet hand to work up a lather, and it covers my whole head. I start in the front, and I am often surprised how it continues to work its way to the back without needing to rub the bar on my hair or reapply. I love the fresh lemongrass scent and how it cleans my scalp really well. The ingredients allows for a non-stripping feeling while working it in. Of course it is a bit clarifying, but my hair does not feel like straw. I follow up with the conditioner bar, and I only have to rub that in my hands as well for each section. It detangles nicely on its own. Smells so good. I’m 8 years in you guys, and all of the Tree Naturals products’ scents compliment one another.
