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 of the things that it does is "wake up" your style. No matter how smashed or smushed my hair is from the night bef...

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...

Just No
After seeing this all over social media I decided to try it. Just awful. My curly hair was dry, frizzy, had no curl shape, and it was so bad I had to stop mid blowdry to rewash my hair to get the product out. Dont bother. Theres way better stuff out there.
No. and no.
Hair Type Straight Hair
Come on. This product is way expensive for what it does. My standard is Aussie but tried this at a friends house. I thought it was decent. So I bought a 5 oz bottle for about $25. After using it for 2 weeks, I went right back to the $3 Aussie. Products like this make women look foolish. Way over priced for no better performance but women buy it as if it is cures cancer! If this were $5 it would be a good value. Save your money and buy a cheaper product.
Not for me
Hair Type Wavy Hair
My hair is thick and wavy and just below my shoulders. It's not a smooth wave, and I need to either straighten it with a flat iron or use a jumbo curling iron to add more defined waves. I can typically use any leave-in spray from Biolage, Pureology, Paul Mitchell, etc., and it works fine. I'm not really brand loyal and am always up to trying something new. Not sure what happened here, but this one was a big miss. After a week or so, I couldn't figure out why my hair was becoming more frizzy, heavy, and unable to hold a style. I blamed it on the weather (humid and windy), thought maybe I needed a cut, then realized I had been using this in my product lineup. Went back to a Biolage spray today, and my hair is back to normal. Disappointed I'm not able to keep this in a rotation, as I've always considered Redken a good, trusted brand.
It was okay
Hair Type Straight Hair
I normally use Redkin All Soft shampoo and conditioner, but thought I'd give this a try. It didn't work well on my dry hair; the All Soft conditioner works a lot better. Thanks, Ulta, for sending me a sample to try. I'm sure it probably works well on most people.
Smell overrides any minimal benefit
Hair Type Wavy Hair
I can't tell if this does anything beneficial for my hair. Been using it almost daily for months just to use it up but I think I'm gonna throw the rest away because the fragrance is VERY strong and very chemically.

- 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
