Love this stuff
My hair is super coily and when I use product to define the curls its often hard to duplicate the style the next day without washing it all over again. This is a miracle product.

One United by Redken
I really wanted to like this product based on all the good reviews and how much help my hair needs. So-I tried the trail size (thank goodness) and now I am throwing the remaining away. I could not tell that it did one thing for my hair except make it heavy, wet and smelly. If you a headache fro...

5 star smoothing conditioner for Curly Hair!
I have fine curly hair,.post washing. My hair tends to mat-up, to the point where I would need to detangle with my hands and at times, cut out the mats as needed. One United spray is a miracle!. After spraying on washed hair, my hair is as fine as silk! My hair has grown longer, quicker, and I need less time w/the hot tools. Hands-down, the Best on the market!
Just fine
The 25 benefits aren't clear to me when I use it. Its a nice leave in conditioner but I can't justify the price when the bottle is so small. In fact, even when I use it I still find myself using all my other leave ins as well.
ABSOLUTELY AMAZING -new must have
So I have bleach blonde hair and blonde hair extensions. Obviously my hair can get a bit dry and tangled because I have some damage from bleaching. I used to always need a creamy leave in conditioner just to be able to brush through my hair, but it was frustrating because my hair would look greasy in about 2 days, and be a bit weighed down, even when I tried to use any type of leave in conditioning cream sparingly. This is the only spray that is super lightweight that I can detangle my hair super easily, and not even need a leave in cream to blow dry my hair. My hair looks silkier, shinier, and healthier than ever. And now I can go four days without washing my hair versus two days , which is amazing since I have so much hair to blow dry with a hair extensions. This is now a must have products for me!
Buying again
This product was recommended by my daughter. I love it. Leaves my hair feeling silky & shiny.

- Q
Does this work for 4A type hair?
- Asked by Curly
- Official Answer By Redken - BEHi there! Thank you for reaching out! Yes, absolutely—our Redken One United Multi-Benefit Treatment Spray is designed for all hair types and textures, and it works wonderfully on 4A coily hair. For 4A hair, One United is especially great because it provides lightweight hydration, helps to deeply detangle, minimizes frizz, and protects against heat damage. Pro-tip for coily textures: Because 4A hair loves rich moisture, we highly recommend using One United as a "primer" or the very first step in your styling routine. Spray it on damp hair to detangle and hydrate, and then layer your favorite heavier styling creams, leave-ins, or oils on top to lock in that moisture! We hope you love the results. Please let us know if you need any other recommendations for your routine!Was this answer helpful to you
- Q
Could this be considered a SPF for hair? I see heat protectant but nothing about UV and wanted to be sure before I purchase
- Asked by liz
- Official Answer By Redken - BEHi there! Thank you for reaching out with this excellent question. To clarify, our Redken One United Multi-Benefit Treatment Spray does not contain SPF or UV filters, so it should not be considered a sunscreen or SPF for your hair or scalp. While One United is an incredible multi-tasking spray that offers 25 benefits—including lightweight conditioning, protection against heat styling tools, and safeguarding your hair against environmental aggressors to help prevent breakage—it does not block UV radiation from the sun. If you are looking for active sun and UV protection for your hair and scalp, we recommend seeking out dedicated hair care products or sunscreens specifically formulated with UV filters to shield against sun damage. Please let us know if you have any other questions as you build your hair care routine!Was this answer helpful to you
- Q
Is this product safe for curly hair?
- Asked by Bmartin
- Official Answer By Redken - BEHi there! Yes, absolutely! Redken's One United All-In-One Multi-Benefit Treatment Spray is safe and highly beneficial for curly hair. While it is sulfate-free and paraben-free, it is not 100% silicone-free (so it may not be suitable if you strictly follow the "Curly Girl Method"). However, for most curly hair types, it is a holy grail product that delivers several key benefits: Effortless Detangling: Curly hair is naturally prone to knots, and One United provides incredible slip to make wet combing a breeze, drastically reducing breakage. Frizz Control & Definition: Infused with lightweight coconut oil, it deeply hydrates porous curls, sealing the cuticle to block out humidity and eliminate frizz. Lightweight Moisture: It deeply conditions without weighing down your natural curl pattern, keeping your bounce light and springy. Heat Protection: If you love to diffuse your curls, this spray acts as a protective shield against heat damage. The Verdict: It is the perfect, lightweight "all-in-one" prep spray to keep your curls hydrated, defined, bouncy, and frizz-free!Was this answer helpful to you
- Q
Can the united all in one treatment be used with the acidic bonding shampoo and conditioner?
- Asked by Nickname
- Official Answer By Redken - BEHi there! Thank you for reaching out about our One United All-In-One Multi-Benefit Treatment. Yes, absolutely! In fact, using One United All-In-One Multi-Benefit Treatment alongside the Acidic Bonding Concentrate (ABC) system is a 'dream team' combination for your hair. While the ABC shampoo and conditioner work to repair the hair's internal bonds and balance its pH, One United acts as the perfect final step. It provides 25 additional benefits, including heat protection, detangling, and added shine, without interfering with the repair benefits of the ABC line. Pro-Tip: After rinsing your ABC conditioner, spray One United evenly on damp hair before styling. It will lock in the moisture and leave your hair feeling incredibly soft and protected. Enjoy your ultimate hair transformation!Was this answer helpful to you
