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!

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

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.

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.

This Redken Extreme Cat Protein Treatment is very good and easy to use.

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!

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.

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.

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!

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.

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!

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.
Date: 25 / Mar / 2013
Nothing special, my hair doesn't look any better but it's softer.

This Redken Extreme Cat Protein Treatment is my favourite product! Brilliance in a bottle.

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!

This Redken Extreme Cat Protein Treatment smells very good and makes my hair stronger.
Looking for a remedy for my bleach-ravaged hair I stumbled across Redken Extreme CAT - and boy, I'm glad I did! After just one use my hair was transformed, my straw-like strands became silky-soft, shiny and strong. I've been using this miracle product for four months now and I don't know how I lived without it. The only negative thing about this product is the spray bottle, it gets slippery and hard to use in the shower. I love CAT and would recommend it to anyone whose hair is suffering from the damaging affects of bleach, heat etc.
This Redken Extreme Cat Protein treatment helped me to get my desire of strong healthy hair. I use it every two weeks with the moisturizing mask afterwards. As a result the hair has length which is not broken or porous! Plus it does not wash out or yellow the colour. I recommend.

I have known this product from my home country. Recently I bleached my hair and needed something to repair my hair. This protein CAT product does it for my hair, I am now using Redken and treat my hair really well. I will buy it again, CAT works for my fine hair.

Recommended by hairdresser to nourish and strengthen my hair to make it grow. Used a couple of times now and hair is super silky, just waiting for it to grow now.

Simply magic in a bottle! If you want strong, healthy, fully repaired hair, then this is all you need. Works wonders on my afro hair.

I would highly recommend this treatment to anyone that has very dry, bleached hair, as it's certainly the only product that is rescuing mine. From the first use of Extreme Cat Protein treatment I was amazed with the results as my hair was definitely much softer (I use Redken Allsoft heavy cream after). So glad I bought this after reading the reviews!

Redken Extreme Cat Protein Treatment is excellent!

I had a really bad highlighting experience which left my hair very dry, brittle and unmanageable. I've used this treatment for a few weeks, two times a week and I must say it really works. Already after one week my hair looked better and felt stronger. To get best results I use this treatment with a moisturizing conditioner. One really pleasant side effect this product has is that it seems to make my hair generally better and thicker. I mean better than before any dying and bad highlighting experience. So I will definitely buy it again.

Couldn't find a replacement bottle of Redkens Protein serum i've been using for 3 years now... so thought i'd give this Redken Extreme Cat Protein Treatment a go. Ive been using it for about 2 weeks now and already seen an improvement to both the quality of my hair and the reduction of split ends! I am really happy with my purchase and would recommend. The only point i would make is that that spraying the bottle with wet hands in the shower is a nightmare and seem to get more on the window panes of the shower than actually in my hair... but that just may say more about my aim than the design! Anyway it's what you do with it that counts and it works wonders.

This product works wonderfull!!! Using this product 3 times a week, makes my hair feel stronger, softer and healthier. I love it, and recommend it to anyone, but especially those with color-treated hair.
