amazing! - 16-05-2018 by

No doubt this product delivers! I have always enjoyed Kerastase products and am always happy to pay the price for a great hair product, especially when they work as intended!
This serum has helped my bleached hair to repair and protect them before, during, and after styling. I separate my hair in 2 sections and use one pump per section (2 pumps total) on the lengths and ends only. I have seen considerable changes after the second application. My ends seem sealed and hydrated as if I just had them trimmed!

Fantastic! - 08-05-2018 by

A fantastic serum! My hair is bleached and this has literally saved my hair. It is in such good condition and my hair dresser cannot believe it!

Kerastase = Saviour - 07-05-2018 by

I love Kerastase so much! When my bleached blonde hair needs a serious pick me up I am straight to Kerastase. I used this in combination with the rest of the Therapiste range and it worked wonders. It contains protein which my hair only requires in moderation. I now use this range in combination with moisture treatments and it works so well to keep my blonde hair intact and healthy. Worth the money. Fab treatment.

Three Words - SAVED MY HAIR! - 29-04-2018 by

This amazing bottle of hair product has saved my long dry hair.
100 percent worth the price, can't imagine never not using it.

This is the best leave in serum on the market - 27-03-2018 by

I have very dry damaged hair, i have tried Blond Pro, Olaplex, Loreal Serum, all of it. I've spent a fortune. I used this serum for the first time this morning when i got out of the shower and my hair is already nourished and healthy. It has actually stopped it looking brittle and the first application!
i cannot recommend this product enough. I know it's expensive but it is 100% worth it if your hair is fatigued like mine (thin and colour treated).

You won’t regret this purchase - 05-11-2017 by

This will save your split ends like nothing else on planet earth. I like to have long hair but I do get damaged ends. This stuff is quick and easy, just swipe across ends and they immediately look and feel much healthier, as well as being easier to comb. Expensive, but a bottle will last ages and ages. Very happy with this purchase, will buy again.

Can’t go a day without it - 02-10-2017 by

Where do I start with this product? I have dry, thick, long hair with many split ends/breakage. After I shower I apply around 3-4 pumps of this serum firstly before any hair creams/oils onto my hair and immediately it looks revived. Years of damage and a lack of trimming, yet this product is so potent that it seals breakage, softens and transforms my brown locks. It has a transparent thin consistency serum pump out along with another white cream that is silky but much thicker in consistency. I can’t put into words how miraculous this product is for my hair, this was my first time trying a kerastase product and I’m not disappointed. I know this product is pricey considering you only get such a small amount BUT it works wonders and a lot of hair products I have tried have not come close to how hair transforming this serum is. I’m going to integrate this hair serum into my hair routine for years to come.

great for thicker hair - 28-07-2017 by

I have very fine, bleached hair, and I found this a little heavy for me, but I think it would work well for someone with slightly thicker hair, great fragrance!

Can live without it! - 21-07-2017 by

I love this product from Kerastase.
My hair was so dry and snapping off.
I tried so many products and none did the job like Kerastase. It is a little pricey but it's so worth it.
Loved how quick the product was delivered.

Split End Savior! - 29-06-2017 by

So I've been on a hair growth journey for a year now and this product has been a life saver. I've noticed that I'm able to go 6 months without getting a trim because it keeps my ends in such good condition. I definitely notice the days that I forget to put it on as well, my ends definitely feel more brittle and like they're about to snap off. It can be quite a heavy product if you let your hair dry naturally after putting it in, so unless you're blowdrying I'd recommend just applying it to the ends.
If anyone is interested my hair went from being (at the longest) down to my eyebrows at its shortest a year ago to shoulder length today. This stuff is a huge part of that, so thanks Kerastase!

Highly Recommend for Brittle Blondes - 10-02-2017 by

I recently purchased the Therapiste Range for thin hair which included the Dual Treatment serum. I was suffering from bleach breakage and my hair was stressed and frizzy. I was a little cautious given the price of the products, having shelled out for "top of the line" treatments before, including Olaplex, which has often resulted in feeling like I've wasted my money. I was highly impressed with this range though. It really nursed and conditioned my hair. Use sparingly, it will work its magic and last quite some time. I made my original purchase September and am only just reordering.

Excellent, but expected from Keratase - 01-10-2015 by

Received today and love so much had to write a review immediately.

Pump expels both oil and cream via dual pump. Emulsify in hands and run through hair. I haven't tried to blow dry with product yet but on dry hair alone feels very luxe. My hair is foiled blonde so is prone to dryness. Has already nourished the ends and left super glossy.

As with all Kerastase products, outlay is expensive but justified by quality.
