What It Is

Multi benefit treatment for all hair types and textures.

What It Does

Leave in conditioner that instantly nourishes and detangles, helps prevent heat damage and is safe for color-treated hair.

What Else You Need to Know

All haircare routines need a do-it-all product that can provide several different benefits. One United is Redken's all-in-one haircare product that can be used for almost any hair need. It can be used as a rinse-out treatment to provide lightweight conditioning, as a leave-in treatment for enhanced strength and nourishment, and with a styling product to provide added softness.

 

One United provides 25 benefits across 3 main categories: Manageability, Protection, and Beauty. This leave-in hair treatment conditions, nourishes, and primes hair for styling. One United also includes Keracare and Coconut Oil to provide heat protection, prevent against hair breakage, and give softness and shine. One United features the Cationic Complex which includes positively charged ingredients that easily bind to hair to condition, detangle, and provide smoothness and shine. This technology also improves the manageability of hair and reduces frizz to make styling easier.

1. Use alone - apply after cleansing or to refresh hair between washes

2. Use with a rinse-out treatment - apply after cleansing and before rinse-out treatment

3. Use with a leave-in treatment - layered after cleansing

4. Use with a styling product - apply before or after styling

 

PRO TIP: One United can be used as a detangling and cutting lotion behind the chair. Additionally, when applying haircolor to Zone 1 during a haircolor service, you can apply One United to mid-lengths and ends of the hair to condition while the color processes. When layering, always apply the lightest product first which is typically One United.

Rated 5 out of 5 by from A little goes a long way I love how lightweight this leave-in is! It makes my hair feel noticeably softer and smoother without weighing it down or leaving it greasy. My hair is much easier to detangle, and it helps with frizz while still leaving my hair feeling soft and touchable. I also love that it provides heat protection, so I don’t have to layer a bunch of different products before styling. A little goes a long way, and it smells great without being overpowering. Definitely one of those products that actually earns a permanent spot in my hair routine!

Rated 2 out of 5 by from not so great I love Redken products and tried to like this but it didn’t give my clients hair enough of softness to get out their tangles. They need to change it up a little more

Rated 5 out of 5 by from Love love LOVE! Perfect for all hair types! It’s not too heavy to weigh down finer hair but it’s also moisturizing enough for thicker/coarser hair. I would, and will recommend this to everyone. I received this product for free in exchange for my honest opinion

Rated 5 out of 5 by from Must have product. I have been using this product in the salon & at home since it launched in 2015!!! It is a detangle spray, lightweight conditioner, frizz reducer… you name it-it does it!!! My only wish is that it had heat protectant in it. It does protect from some heat. I will use & recommend this product to everyone forever!!!
