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.

I tried these as they were recommended by my mom. I am in love! After the first time using it my hair was happy! It stays woth volume, less fallout and just healthy and happy. I will forever be a customer and will tell other about this also!

I have extremely fine, thin 51 year old dyed hair and Dallas adds volume to my hair. I was extremely skeptical at first bc the shampoo is thick and doesn't bubble as much as I like. The conditioner also feels a touch heavy and doesnt leave my hair feeling as smooth as keratase when its rinsed out. However after my hair is dried it has incredible volume! I use a little blue edition mousse at the roots , blow dry then about 10 mins in large hot rollers and I get great bounce and lift at the roots. I finish with the astronaut humidity spray and cult favorite hairspray and my 70s shag lasts all day. The smell is nice too. Sorta earthy sorta old Aveda. Highly recommend for anyone with fine, thin hair.

I was skeptical if these would work. IT DOES! I have very thin hair. Used the shampoo & conditioner a few times and I do see a difference. I will continue to purchase these products.

I had never found a thickening shampoo that did what it claimed it’d do. This one is an exception for me. It truly works. Yay!

I love how much my hair smells and feels after washing my hair with this shampoo & conditioner. Gives my hair that added boost of volume and lasts throughout the day.

This shampoo lasts a long time because a little goes a long way. My daughter with super long, thick hair was really impressed with how little she had to use compared with other shampoos.

Even though I have some wave in my hair, the age induced thinning has needed help. I get the fullness that I no longer have. And the fragrance is wonderful!

My daughter and I use these products and our hair looks amazing.

First off, I love the smell of these products! So nice, not overpowering and elegant. Love it. I can really feel a difference in the texture of my fine blond hair when I use the shampoo and conditioner combo. I’ll be buying again .

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.
