Love This Shampoo

I really love this shampoo and conditioner. So why, you may be wondering, am I only giving it three stars. Well, this may seem a bit unfair, but I’m giving three stars because my Zig Zag root teasing spray stopped working half way through the bottle. While I know this review is for the Dallas shampoo, I think R+Co’s packaging leaves something to be desired. I don’t expect anything extravagant, especially if it’s eco-friendly, which I prefer, but not only did my Zig Zag stop working, my conditioner is nearly impossible to get out of the bottle. I have to balance it upside down to avoid shaking it profusely to get anything to come out. Maybe this is nitpicky, but these are fairly pricey products, so I expect both the product and packaging to work well. Btw, I LOVE the Zig Zag spray but will not be buying more for fear of it being wasted like my current bottle.

Fantastic Shampoo

I love this shampoo and what it does for my hair. I am using Dallas now but I have also used Television and Gemstone. The hairspray is fantastic as well.

Daily drivers

I have damage from years of color and bleach and this is my favorite reliable set of shampoo and conditioner. It checks all the boxes of smoothing, protection, repair, and not leaving behind heavy residue. Love love love

Dallas biotin thickening shampoo and conditioner set

I started my journey the First of the year 2025 with the Bleu shampoo and conditioner set and it is now 11/2025 and I switch between the Bleu and the Dallas set. My hair has never been more healthy or strong. I highly recommend this brand.
