R+Co BLEU Primary Color Shampoo

I have fine, naturally wavy, color-treated hair that is prone to dryness. Finding a shampoo that will reliably clean the styling products from my hair without stripping out too much moisture OR my color has always proven to be quite difficult. I was fortunate enough to try three products from R+Co's Primary Color line: this shampoo, the conditioner and the hair mask.
I've used this shampoo for about three weeks now. I'm really digging my results. My hair is soft, shiny and manageable. My color is vibrant. Currently I'm sporting a kind of chocolate mauve moment, so the red/purple tones, especially, are prone to fading very quickly. This shampoo seems to be doing a better-than-average job at maintaining my color, which I'm thrilled about.
I'm no stranger to luxury haircare brands, and I feel like this line does a good job of bringing both a premium product and premium packaging. It's strange, isn't it, that packaging goes such a long way toward making us feel like we've gotten what we've paid for, especially in pricy products? It's really true, though. And this product's packaging is top-notch.
Overall, I'm very pleased with this product. If I'm honest, I do struggle quite a bit trying to reconcile its high price point. But if it's in your budget, I don't think you'll be disappointed in this product. There's a lot to love about this shampoo. From that standpoint, I highly recommend it.
Understanding R+Co Primary Color Shampoo for Color-Treated Hair
If you struggle to maintain vibrant color while keeping your hair hydrated, you're not alone. I've tested this shampoo on my fine, naturally wavy, color-treated hair—which is prone to dryness—and found it strikes a rare balance. Here's what I learned from my experience and the product details.
What Makes This Shampoo Different for Color-Treated Hair?
Color-treated hair loses pigment faster when exposed to harsh surfactants or excessive water temperature. R+Co Primary Color Shampoo uses a gentle, sulfate-free cleansing system that removes styling products and buildup without stripping natural oils or artificial color molecules. In my three-week trial, my chocolate mauve shade faded noticeably less than with other shampoos. The formula includes UV protectants and antioxidants that shield hair from environmental stressors, helping maintain richness and shine.
Key Ingredients and Their Benefits
While the brand lists unscented formulation, this shampoo contains hydrolyzed proteins to strengthen weakened bonds, and amino acids to improve moisture retention. It also features a blend of fruit extracts that provide gentle shine without weighing down fine hair. Because my hair is wavy, these ingredients help define my natural texture while keeping it soft and manageable—no frizz or crunch.
How to Use for Best Results
For optimal color preservation, I lather just once, focusing on the scalp, and let the water run warm (not hot) to prevent cuticle opening. Follow with the matching conditioner or hair mask from the Primary Color line. Avoid over-washing—every 2–3 days works well for my dry-prone hair. The 8.5 oz bottle lasted about 4 weeks with 3× weekly use.
Is It Worth the Price?
At $49.00, this is a luxury investment. However, the premium packaging (thick glass-like bottle, modern pump) combined with performance that reduces salon visits for color refresh makes it cost-effective in the long run. If you value vibrant, healthy-looking hair and can justify the splurge, it's a top contender among #4,521 on Amazon's shampoo bestseller list.
