If you are looking to improve the quality, restore elasticity and improve the overall look and feel of your hair this is the ONLY product to use. Do not waste money on inferior products as this truly bonds the hair strand and delivers results. I used to let it sit when in the shower but I prefer to leave it in longer 20 minutes while I do other things and it lasts longer during the week.
I can see immediate results after one use; incredible product.
My hair is very dry and frizzy. Acidic bonding helps to keep it in check, I use it regularly to keep my hair manageable. I try other brands of pre-shampoo and post conditioning products that say they bond though I keep coming back to this. Worth a try to see if it's for you.
Amazing! Just need to bring back in stock. Must have
[This review was collected as part of a promotion.] Using this makes my hair feel brand new! I dye my hair every month and this does wonders for me!
This is the best hair product that I have ever tried. Visible results after only one wash as promised. Good job, redden team.
Amazing! Use this if you have dry overprocessed hair.
I have tried many bond repair products but this one is far better than others. Leaves my hair smooth and radiant. It’s not a miracle product but you can see and feel the difference after one use. I love it very much and it’s part of my hair care routine.❤️
Every time I use it I can feel my hair immediately smoother (I have permed and colored hair). Only thing is that it’s an extra step you add in your hair routine and it’s a bit pricey.
[This review was collected as part of a promotion.] My hairdresser passed away last year. I haven’t had a haircut in almost 2 years. I’ve had to use hair color off the shelf or previously she had colored my hair and kept it in wonderful condition. Needless to say box die, and no haircut mean dry straw ends this acidic bonding concentrate put new life into the ends of my hair Now I just need to find someone new to cut my hair. It’s surprisingly difficult as grief gets in the way. But at least I have the acidic bonding concentrate In the meantime, which gives me presentable hair. It’s easy to use and really seems to work. The one caveat I would give is it does make my hair soft to the point of losing some volume.
[This review was collected as part of a promotion.] I love this product. Within 6 weeks of using it I saw less breakage and less shedding. Highly recommend!
[This review was collected as part of a promotion.] The Acid Bonding Concentrate Intensive Treatment is a quality product that creates efficient results to healing damaged hair.
I used this product every week and waited to finish the bottle to see if it does any difference before writing a review. Unfortunately, it didn't addressed any of my hair concerns. Won't be buying again.

I rotate between this and K18 once a week and prefer this over K18. Product spreads better and hair feels slightly stronger in comparison. Much more economical
[This review was collected as part of a promotion.] It made my hair so smooth and think, my hair use to be is thin.
Love it ! Made my highlighted hair so soft and shiny! I use it twice a week as i have highlighted hair. Sometimes i leave it overnight and wash it in the morning is that ok ? I have tried to enter a question but couldnt so i left a comment

The entire acidic bonding complex system is the BEST conditioning product(s) system I’ve ever used, and as a hairdresser I’ve tried them ALL!
A few months ago, against my better judgement, I decided to hi-light my hair myself when my daughter who is also a hairdresser wasn’t able to get me in for an appointment for what seemed like an eternity!
I’ve hi-lighted my own hair before, but since my daughter has been doing it for me, I was terribly out of practice trying to get the foils in perfectly. Well… I ended up with some real brassy pieces, so of course “if at first you don’t succeed, try, try, again” which I did, over and over, until my hair was like a haystack! We’re talking straw!
As a professional I knew better, and should have taken my own advice I give to clients, however, I think because we know how coloring works, and understand how to color correct, we can sometimes experiment way too much on ourselves, to our hairs detriment!
I started using the Acidic Bonding Complex System, and what it claims is TRUE; from the very first use, my hair responded like it’s NEVER responded before!
,
I mean, my hair came out shinier, softer, 1000x more beautiful than before I messed it up,
If anyone has any doubts, I say TRY IT ANYWAY, what do you have to lose except damaged, dull, dry lack-luster locks? This system TRULY rescued my hair like nothing ever before!
Oh, and I receive at least three or four requests per day for the name of my stylist! Just amazing!
This product gives me the soft smooth curls of my dreams. I’m amazed! I have been using it for at least a year every two weeks. My fine-to-medium 3b/3c curly hair loves the stuff. *Note: silicones work great for me, and my hair did not respond well to the curly line
[This review was collected as part of a promotion.] You can noticed the difference since the first use
I want sure this would do much. It really appropriate me. My hair looked and felt so mush better!
Loved this product. My hair loved it!! Felt soft and bouncy.
[This review was collected as part of a promotion.] I was using Olaplex for a long time. I saw a UTube video saying Redken bonding system was better. So I tried it.
Guess what? IT REALLY IS!
[This review was collected as part of a promotion.] This treatment has changed my hair! I am loving it!
[This review was collected as part of a promotion.] Love this treatment! It kept my hair nice and smooth! I continued to purchase after receiving this box. Smells great and even my fine hair seems to be doing great
[This review was collected as part of a promotion.] great i loved it, transformed my hair completely thank
I typically wash my hair 3 times/week, and will use this product 1-2 times/ week prior to shampoo depending on how much heat I’ve used since my last wash. I have been able to grow out my length and get less trims because my ends feel healthy!
I can honestly say I absolutely loved it and even bragged to my stylist about it but I have suffered two full months thinking I was losing my eyesight. I thought I had pink eye then allergy eyes as my eye lids and around my eyes were so red and itchy. I couldn't get into my eye doctor as she is so booked out so I tried everything from drops to allergy wipes and cortisone cream. I didn't associate it with my shampoo because I only use it twice a week until things started getting worse and I knew the only new thing I was using was my shampoo and conditioner. I decided to stop using it and my eyes started to feel a little better so I have the shampoo and conditioner one more try...OMG. they stayed up all over again. Now after two months I finally have some relief because I stopped using it. This is a great shampoo but has seriously caused me stress and fear of having blurry vision in one eye. Good luck if you decide to use it.

Amazing! My hairstylist always uses this product on my hair before she does my highlights, and it makes my hair so smooth and soft just pure perfection the best product I’ve ever used for my hair.. love love love 💗🥰
Makes my fine thin hair feel & look so much healthier. I got a perm 4 months ago & Ive had major breakage- it seems to have helped with the breakage & made my hair stronger.
This is an absolute game changer. I've used so many different treatments and was stunned at how amazing my hair was from years of bleaching and heat and used it 1 day after 2 full rounds of full head lightening my hair was like straw and after ONE time with the 4 products it looked and felt amazing and didn't remove the toner
[This review was collected as part of a promotion.] Smells good and loved how it left my hair, smooth and clean and smelling good, this treatment works i have used it before and love how it helps my hair
[This review was collected as part of a promotion.] It’s hard to talk about how effective something is when you don’t carry the whole line. But this product smells nice and a did notice a smoother texture to my hair after using it for a few months
Last year i got really into haircare when my hair got severely damaged by bleaching the whole head. At first i was using other bond builders and yesterday i tried this for the first time. Just let me tell you that the results i got from this in one use cannot even be compared to other products on the market.
My hair feels stronger to the touch, looks much healthier, ends look absolutely fabulous and i am frizz free. I think that the citric acid does wonders for me
I bought this at the recommendation from the blowout professor on YouTube. and I am glad I did. I never would have thought a product like this would work. I only use a small amount and follow the directions, but i am noticing a change in my hair. My hair has more moisture and is manageable.
[This review was collected as part of a promotion.] Incentivized by Redkin and Influenster. This product is amazing. I regularly get my hair colored so I’m glad I was able to try this out and fall in love with a product that helps my damaged hair. Highly recommend.
[This review was collected as part of a promotion.] Ever since they sent me this I was so excited to try because I bleached my hair so bleach hair becomes damage over time so this product helps with dry ends and split ends and hydrates your whole hair for repair any color treated hair need bonding treatment
By providing hair with additional nourishment, a pre-shampoo bonding treatment works for those experiencing weak, damaged or dull strands. They work by giving your hair a thorough pre-wash and an instant boost in nutrients to help damaged hair recover, while also helping hair grow longer and stronger.
The Redken Acidic Bonding Concentrate Intensive Treatment helps to strengthen weakened hair or hair that is prone to damage. Infused with rich ingredients, this treatment works to boost and nourish hair that requires stronger bonds. By applying this treatment, hair will also have the ability to absorb the best nutrients from your shampoo and conditioner. By adding a pre-shampoo treatment to your hair care routine, hair will appear smoother, stronger and more healthy in a short period of time. Learn more about the Acidic Bonding Collection for Damaged Hair.
In most cases, you should use a pre-treatment 2-3 times a week. This may mean using the treatment every time you wash your hair if the hair needs support and revitalisation. How frequently you should wash your hair depends on your hair type.
Yes, you should apply the pre-shampoo bonding treatment to your hair roots and work down to the ends of your hair, just like when you shampoo your hair. If you have a lot of hair, divide the hair into two or four sections for even distribution. Coat the hair in the product from root to tip before thoroughly rinsing and continuing to shampoo your hair.
It is not recommended to use the Redken Acidic Bonding Concentrate Intensive Treatment on its own, without completing the rest of your hair care routine. For best results, use the pre-shampoo treatment for damaged hair and follow with the coordinated shampoo and conditioner.
