        THE best fragrance free shampoo

        Seriously, I have tried probably 20 other brands and they didn’t come close. I pair it with the fragrance free conditioner.

        Excellent. Need bigger bottles!

        The perfect shampoo when you haven’t washed your hair in days, or when you just washed it yesterday. Cleans thoroughly and makes a perfect base for a thicker treatment, mask, or any conditioner. Can’t think of a reason to use any other shampoo.

        Perfect for Travel

        This was great for a recent weeklong vacation - these were the right size and I had no spills in my suitcase. 10/10!

        Nice shampoo, but you NEED the conditioner.

        This shampoo cleanses really well, but I can't use it without the conditioner. It's quite drying and using it alone makes it difficult to even comb my hair afterward. However, when used with the conditioner, my hair dries shiny and healthy looking. As to the claim of helping thicken hair...? I can't say I've noticed any difference after months of using it. Still makes my hair clean and shiny so I like it.
