Instantly replenish your hair's moisture levels with Redken Extreme CAT Protein Treatment. Redken's patented taurine technology and cationic proteins help reconstruct and fortify your damaged hair leaving you with soft, silky locks.
Redken's 3D Repair Complex builds long lasting strength and conditioning into your hair leaving it healthier and more manageable. The Extreme CAT Protein Treatment is specially formulated to provide a triple line of defence; proteins penetrate deep into the core of your hair helping build internal strength; ceramide enters the cuticle layers to reinforce the structure and help repair any damaged areas; and natural lipids, like those found naturally in your hair help to resurface your hair leaving the cuticles shiny, smooth and protected.

I was recommended this product by a friend who has very blonde hair and it's worked wonders, I on the other hand are very dark and really just needed something for my ends!! It has done a job and helped out the issue, it didn't completely rejuvenated my locks but would be wishing for a miracle if I expected that there was any treatment out there that would make my hair "perfect" other than just having a good cut. If i couldn't find anything I liked more then i would probably buy this again.

I love this product. It is well priced, smells great and really does the job.
Some advice :
I do give my towel dried hair a quick squirt before using the hairdryer and I find it makes my hair look really healthy ( only a small bit as the protein can make hair hard) as I do find it annoying standing in the shower shampooing rinse - then spray in treatment wait 5 minutes - rinse ( yawn..) - then condition rinse etc...!

I had a hair disaster and it needed re colouring again immediately which left me with very dry , over processed hair.
I researched on line and found Redken extreme CAT. After just 2 applications it is starting to work. The softness and shine are returning and the frizz is going. Great product.
Also much cheaper on lookfantastic.

I was recommended this product by my hairdresser as my highlighted hair is dry and heat damaged. I have only used it a few times and I am already seeing a difference. My cuticles are much smoother. Very pleased so far!

I lighten my hair and it can be quite dry,this product really helps soften it definitely recommend this

Feels good on hair, will see benefits for hair after long term use. Bottle is imposible to use under shower!

Recommended! Product helps tangled hair after bleaching. But still struggling to get the perfect blend of protein and moisture. Use this product in combination with moisture mask. Protein, moisture, protein, moisture...

I'm on my 4th bottle of this, can't recommend it highly enough BUT I think its important to note that it took me a little bit to get the mix of products right. If you have to much protein your hair will be hard, I balance this with the super soft mask as my conditioner. I have long, fine but wavy hair that is naturally dry, its taken me this long to understand it and work out how best to deal with it.

Since I was pregnent so have my hair been living it's own life.
But this spray/treatment are a gift from god, and can't survive without it.
Really recommend this, and if you have a chemical treated/bleeched hair then this is a must have.

Really has made a difference to my bleached damaged hair. It feels and looks a lot stronger. Use once or twice a week.

As recommended by my hairdresser. Bleached hair needing protein. Early days but doing something :)

I have been using this product alongside the redken extreme anti snap treatment for almost a month now and can see a dramatic change in my hair. My hair is heavily bleached as I have it dip dyed, it ended up so dry and snapping at the ends when I was washing my hair and combing it! I decided to invest I. Redken extreme products and you defiantly get what u pay for, my hair looks and feels I'm miles better condition! Would buy again. The only slight down fall to this product is it doesn't last very long u like the anti snap treatment which I use every day n still loads left :)

I have been using it for a couple of weeks so far and my hair feels healthier, stronger and less damaged.

This Redken Extreme Cat Protein Treatment is the best! Used it a few years ago, and thought I would give it a try again now. I don't regret that desicion! Now I use it once a week, and make sure to re-order in plenty of time, so I don't run out. Last time I ordered it, I even got a discount, and ended up paying just over 1/4 of what I pay at my local hairdresser (!)

I have extremely dry and very long layered hair. Due to frequent colourings, my hair became extremely brittle. Redken Extreme Cat Protein Treatment is SOO amazing! My hair becomes super silly and soft and I'm not struggling to comb through my hair anymore. Use after shampoo and follow with a conditioner. LOVE IT!
22 October 2013 by
Redken Extreme Cat Protein Treatment is good but I prefer the redden stuff that you leave in and when I use this it doesn't make it any softer and gives a nasty texture to my hair
14 October 2013 by
Have only used this Redken Extreme Cat Protein Treatment twice so I can't really comment on long term effects. However, I have not seen much immediate improvement to my hair condition so far.
23 September 2013 by
This Redken Extreme Cat Protein Treatment is amazing. Makes my hair feel much stronger and people always comment about it's great condition when I'm using it. It lasts for ages and is good value.
9 September 2013 by
This Redken Extreme Cat Protein Treatment is very good and easy to use.
26 August 2013 by
This Redken Extreme Cat Protein Treatment is great, it makes my hair feel silky. I would recommend to my friends.

I often stock up whenever I see a sale on... I love this Redken Extreme Cat Protein Treatment! I stupidly bleached my tight curly hair 18 months ago and it's still fairly damaged. Using Cat treatment in between a shampoo and a deep conditioner has helped to restore a lot of the protein and strength and has helped me to grow my hair long. For me this is a must buy and I'd rate it 6*'s if I could!
17 August 2013 by
This Redken Extreme Cat Protein Treatment is great for strengthening weak or damaged hair. I was very pleased with your prompt delivery.

I bought this Redken Extreme Cat Protein Treatment along with the rest of the Redken Extreme range (shampoo, conditioner, masque, CAT protein, Anti-Snap Treatment).
This was the product I was most disappointed with. This is mostly due to the application. I've been applying this product after washing and towel trying, before following with the conditioner or masque. However this product is a clear liquid, looking and feeling just like water, making it impossible to judge just how well you've covered your hair in it. I honestly have no idea just how well the product is distributed across my hair, and this means I end up using loads of it just to make sure I've covered everything.
After all that, I can't say I even particularly notice a difference. I wouldn't buy this product again, I would just stick with the Redken Extreme shampoo, conditioner & masque.

This Redken Extreme Cat Protein Treatment is ideal for fragile hair that needs a specialised treatment, it helps hair to repair itself by putting in the needed proteins into its structure. It makes hair feel deeply hydrated and renewed.
30 July 2013 by
I have had this Redken Extreme Cat Protein Treatment before when I used to highlight my hair, and now that I'm letting my hair grow long again it's just as fantastic. I use it with the Redken Extreme Conditioner, which is also amazing. Smells good too, not candy-like or perfumed like most other ones. The CAT treatment doesn't smell at all.
12 July 2013 by
My hair is so much stronger from using this Redken Extreme Cat Protein Treatment! It's feeling a lot less damaged and with a lot less breakage. It even feels like it's grown a bit too!
29 June 2013 by
I swear by this Redken Extreme Cat Protein Treatment! in the last year, my hair has been 20 different colours ranging from ash blonde to black. Obviously dying my hair this much meant it got damaged, and I tried so many different products before deciding that this one is by far the best.
26 June 2013 by
Very good Redken Extreme Cat Protein Treatment that helps to rebuild the structure of every single hair.

I think this Redken Extreme Cat Protein Treatment is a great product, but if you have long hair it will not last for so long. I have not tried it too many times, but my hair feel better already!
23 May 2013 by
This spray made my hair noticably stronger after one use.
You spray it on and work it into a lather and leave it for a few minutes.
The only thing I can say is that bottle could have been designed better as you can't really grip it when you have wet hands.
The product itself works well

After reading reviews I was expecting softer, shinier hair after using Redken Extreme Cat Protein Treatment (150ml), but I honestly have not felt any improvement in condition after 3 applications. Disappointed.
26 March 2013 by
Nothing special, my hair doesn't look any better but it's softer.
25 March 2013 by
This Redken Extreme Cat Protein Treatment is my favourite product! Brilliance in a bottle.
19 March 2013 by
Redken Extreme Cat Protein Treatment is a life saver and transformer. It gives strength and makes my hair look fabulous. I adore this product.

I've just had highlights and lowlights twice in the last week, due to ending up with thick bands of colour last Saturday, (and she also used bleach ) which looked terrible, so I had no choice but to get them redone ( at another salon) on Thursday.
Thankfully the colour is great now,but my hair is now in a really dry state. I've just used a very generous amount of Redken Extreme Cat treatment, followed by a deep conditioner, and after only one treatment ,my hair is about 80% better !
Fantastic product with fast results! I'll definitely keep using it until my hair gets back to normal.

i bought this product hoping to improve the quality of my hair.
everywhere i read it says that it is not a result you will see immediately, so i guess i will have to wait and see.
when i read how to use the product it only said to apply after shampoo, and them clear. so i did not apply conditioner after this product.
this was probably the first time in my life that i didnt apply conditioner to my hair, and if i'm honest it wasnt so bad, but still was not too happy about it.
so i did some research and i found our that after you rinse this product you can apply conditioner and then of course rinse it.
i bought the extreme conditioner from redken, and WOW.. what a difference!
maybe it was obvious for some people to apply conditioner after the product, but if you are like me that follows the instructions as shown in the bottle YOU CAN APPLY CONDITIONER AFTER, even if it does not say it anywhere.

My bleached, blonde hair felt better in just two weeks after using the Redken Extreme Cat Protein Treatment (150ml). Really recommend this product if you want to heal your damaged hair!
