This Concentrated Hair Care Line Is The Solution To All Of Your Damaged Hair Woes

If you’re dealing with damaged hair, you’re going to want to pick up the Redken Acidic Bonding Concentrate system. Read on for our full Redken Acidic Bonding Concentrate review.

I’ll be the first to admit that I’m an impulsive person. While logically I know I should think things through before diving in, I rarely do—and often, I’m left dealing with the fallout shortly after. So naturally, when the inspiration to dye my naturally thick, chestnut hair platinum blonde struck recently, the planning process consisted of little more than me running to my local drugstore and picking up a box of the cheapest white-blonde dye I could find. After failing to transform my tresses adequately (no surprise there), I did it again. And again. 

Needless to say, bleaching my hair three times within 24 hours was a bad idea. Though I later got the color fixed by a veritable miracle worker at my favorite salon, the damage had been done: My once-glossy mane was completely fried. Luckily, a colleague noted my distress and reached out to me, asking if I’d like to try Redken Acidic Bonding Concentrate, a four-step haircare system formulated specifically for damaged, color-processed hair. Of course, I accepted: Not only was the system designed to address my exact hair concerns, but Redken products were also a major step up from the drugstore shampoo and conditioner I’d been using previously. I was very excited to see whether or not the three-step system could actually help restore my hair’s healthy appearance. Spoiler alert: It did. Read on to learn exactly what the Redken Acidic Bonding Concentrate system is and how it added life back into my sad, straw-like strands.


Can Over-Bleached Hair Be Repaired? 

First things first: Over-bleached hair can’t actually be repaired. Bleach not only removes the natural pigment in your hair, but also strips the hair’s outer cuticle. This gives the hair a rough texture and leaves your strands more brittle and prone to split ends and breakage. These physical changes are irreversible once the damage is done. If your hair is severely damaged, your best bet is to go to a salon for a professional haircut and treatment. That said, while you can’t undo the damage, the right haircare products can help improve the look and feel of your hair while you wait for new growth to come in. 

What is Redken Acidic Bonding Concentrate?

Whether you have hair damage as a result of bleach, heat styling, or chemical treatments, dealing with it is never fun. The right products, however, can be the answer to helping to restore the look and feel of your mane. That’s where the Redken Acidic Bonding Concentrate comes in. Formulated for all hair types and textures, this all-in-one concentrated system for damaged hair provides ultimate repair, intense conditioning, and color-fade protection.

Our favorite part: This range also kicks off Redken’s newest product packaging innovation. The packaging is made of recyclable plastic making it the perfect addition to your green beauty routine. The brand also teamed up with  The Braille Institute to add Braille to the packaging, making the products more accessible to all consumers.

How does Redken Acidic Bonding Concentrate work?

The Redken Acidic Bonding Concentrate is formulated with citric acid, an alpha-hydroxy acid used in a variety of skin care products, and the brand’s Bonding Care complex. These ingredients work together to reinforce weakened bonds to help build your hair’s strength and resiliency.

The acidic formulas defend against the damaging effects of hair coloring, styling tools, and even water while also helping to rebalance your mane’s natural pH levels for healthier-looking, stronger hair. When used as a complete system, you can experience a 56 percent reduction in hair breakage, an 82 percent reduction in visible split ends, and hair that’s 11 times smoother. 

What is Redken Acidic Bonding Concentrate Intensive Treatment?

The latest addition to the Acidic Bonding Concentrate family is the Intensive Treatment, meant to be used as the first step in the routine. You may wonder, “Why would I need a fortifying treatment before applying strengthening shampoo and conditioner?” but hear us out.

Redken pros explain that hair stretches up to 50% when it’s wet from shampooing. Stretched hair is weak hair, so this can result in further damage to the hair fiber during the washing process—but that’s where the Intensive Treatment comes in. The formula is designed to pre-treat hair using the highest level of citric acid available in the Acidic Bonding Concentrate system, which is small enough to enter the hair fiber and strengthen hair from the inside out. This reinforces the weak bonds and prepares hair to receive the full benefits of the Acidic Bonding Concentrate range. We love a little science!

How long can I leave the Intensive Treatment in my hair?

No longer than ten minutes. Any usage beyond what’s instructed has not been validated and will not guarantee additional results.

Can the Intensive Treatment be used every day?

Yes! The Acidic Bonding Concentrate Intensive Treatment can be used regularly and as often as each shampoo. Watch the quick video above to see how the line works its magic on damaged hair.

What type of hair is the Intensive Treatment best for?

The Intensive Treatment is suitable for all hair types and colors. However, those with damage will notice the most improvements after using it. If your hair is feeling the stress from chemical processes, environmental aggressors, coloring, or heat-styling, the Intensive Treatment is a must-have in your routine.

As mentioned, the Redken Acidic Bonding Concentrate range is perfect for anyone dealing with any kind of hair damage, no matter your hair type and texture.

How Do You Use Redken Acidic Bonding Concentrate?

When used together, the four products in the Redken Acidic Bonding Concentrate range will improve breakage reduction, reinforce weakened bonds, and provide silky-feeling, conditioned hair.

First, before you shampoo dampen your hair and apply the Intensive Treatment throughout your strands, leave on for five to 10 minutes. Then, lather the treatment throughout your stands before washing your hair with the creamy shampoo, then nourish your strands with the rich conditioner. Finally, after getting out of the shower and gently towel-drying your hair, you’ll comb a generous amount of the hydrating leave-in treatment through your damp strands and dry your hair as usual (for me, that meant air drying—my haircare routine is pretty low-maintenance).

Gillian before using Redken Acidic Bonding Concentrate 

After using the Redken shampoo and conditioner for the first time, I immediately noticed my hair felt smoother and more manageable than it had with my previous haircare products. The leave-in treatment only amplified these results, and after the first use of the full regimen, my hair was noticeably healthier-looking. Since my hair was so damaged, I opted to use the products every day, though you can use them every other day if you wash your hair less frequently. After each use, my hair felt silkier and stronger. I also noticed that some of my hair’s shine had been restored, and I had fewer flyaways, even when I used hot tools to style my strands (which usually leaves my mane looking very frizzy).

I’ve been using the Redken products now for about three weeks, and though my expectations weren’t super high (until recently, I was half-expecting my hair to suddenly fall out), I can say that the system far surpassed what I’d hoped for. My hair is now significantly easier to comb and feels much smoother and less brittle than it did previously. And, it’s not just me: Both my boyfriend and best friend commented on how great my hair looked, totally unprompted. Since my hair is now the color I’d originally aimed for and no longer looks like I lit it on fire, I plan to keep the blonde. I’ll be using the Redken Acidic Bonding Concentrate system in my daily haircare routine for the foreseeable future—until, of course, my impulsivity takes over, and I decide to change up my look again.
