I love this shampoo refill for keeping my hair happy and healthy while cutting down on plastic. From the first wash my hair feels softer, smoother and full of life without ever feeling weighed down. The amino acids and hydrolysed wheat protein really help keep moisture locked in, while the fairly traded coconut oil adds a subtle shine and silky finish. It leaves my fine hair feeling light, bouncy SimplyHilary · spacenk.com

Ok so! I love this shampoo. This has been the only shampoo to clean my hair and bot dry it out. My natural gwols know how frustrating it can be to wash, moisturize and style your hair and then it be dry and toe up the next. I know how it feels to buy a hundred plus dollars of products to be disappointed or mixing them with new products so money isn't wasted. I washed my hair the first day I bought Mia · ulta.com
