Love!

Super sudsy and makes my hair feel clean!!! My hair is getting thick!

High Quality

This shampoo bar suds up immediately when it hits water so I can wash my hair using less shampoo, which makes the bar last longer. I also appreciate the clean feel it gives my hair and the natural detangling and silkiness it provides for my hair. The only concern I have is that I haven't yet seen results of it making my hair thicker and preventing my split ends. However, it has made these concerns more manageable, and I am confident it will begin to work after I have used it for a longer time.

Cleans beautifully, low carbon footprint

Once around your head with this little bar does the trick. I wet my hair first, and then rub the bar right on my head and it gives you a great lather. I love their customer service and the fact that there is no plastic packaging for this product. I buy three bars at once to further reduce my carbon footprint . Great company, great product.
