Hair The One Signature Salon Sulfate Free Shampoo for Moisture, Softness + Shine - Avocado Oil - Anti Frizz + Clarifying - Hydrates + Repairs - Vegan, Paraben Free + Color Safe

This shampoo is a great value - I need less of it than my cheap shampoo (which is a good sign of a quality product), it smells nice, lathers up well and feels silky to the touch. My hair is smoother and less frizzy and it looks healthy and shiny! I'm completely sold - LOVE IT! Since you need less product, you're really not spending more than you would with a cheaper shampoo.

Wonderful clarifying shampoo with excellent lather. Does not not dry the hair. Smells great too! The bottle is large and for the price, it lasts forever since it’s concentrated.

I’ve been using Kristin Ess Hair One Signature Shampoo for a really long time, and it’s made my hair feel really soft and clean without stripping it. It lathers well, rinses out easily, and leaves a light, fresh scent. My hair looks smoother and less frizzy even without extra products. It’s gentle enough for daily use, and a little goes a long way. This is my most repurchased shampoo. Highly recommend if you want a simple shampoo that delivers healthy, shiny results.

Worth 10 stars! I'm 72 and my hair is gray, which tends to be dry. This shampoo is wonderful! I don't even need to use a conditioner. It works great and smells great. It leaves my hair manageable, full, and shiny. Kistin Ess is the best shampoo I've ever used!

I am obsessed with this shampoo. My hair always felt super clean while using this product and didn’t feel the need to double wash like I do with other brands. ALSO, the smell of this product is absolutely amazing, and would stay in my hair for days. I will say I have temporarily stopped using this product for hair health purposes, when I scanned this shampoo in Yuka, it had some questionable ingredients, but I will return after I finish my bottle of this other shampoo.

⭐️⭐️⭐️⭐️⭐️ 5/5 – Absolutely Obsessed with The One Signature Duo! I rarely leave product reviews, but I’m so impressed with the Kristen Ellis The One Signature Shampoo and Conditioner that I had to share. From the very first wash, I noticed a difference. The shampoo gives that perfect clean feeling without stripping my hair or leaving it dry, and the conditioner makes my hair unbelievably soft and smooth without weighing it down. My hair just feels healthy again — light, bouncy, and shiny in a way it hasn’t in a long time. The scent is another standout. It smells luxurious — fresh, slightly warm, and salon-worthy — and it lingers just enough to make your hair smell amazing all day without being overpowering. Every time I wash my hair, it feels like a mini spa experience at home. What I love most is how balanced these formulas are. My scalp feels clean and refreshed, but my ends feel deeply nourished. I’ve tried countless salon brands that either left buildup or stripped my hair, and this duo manages to do neither. It’s rare to find a set that works this well for everyday use and still gives that “just left the salon” finish. I also appreciate that a little goes a long way — both the shampoo and conditioner have a rich, concentrated texture, so you don’t need much per wash. My hair has more shine, better texture, and looks healthier overall. Honestly, this combo has earned a permanent place in my routine. If you’ve been searching for a shampoo and conditioner that truly make a visible difference, The One Signature line is exactly that — the one!

This shampoo make my hair feel so clean. I have used so may different products in my time and this is the first one that honestly makes it feel like there is no residue left on my hair. The scent is not overpowering like some shampoos. I do not get an oiliness after but it does leave my hair shiny and feels thicker. Doesn’t feel dried out either

Nice shampoo. I only use sulfate free and this is a much better price than the purple bottle "ology" brand I was using. It works just as well for me. Leave my hair clean and soft and easy to work with.
