I have long highlighted hair and this Kérastase serum is a game changer. I put it on freshly dried hair every time and it adds moisture, frizz control and my hair is shiny and looks so healthy. Highly recommend!

love it

[This review was collected as part of a promotion.] The **Sérum Thérapiste Hair Serum** by Kérastase is a fantastic solution for repairing damaged, over-processed hair. Its lightweight formula smooths and nourishes hair without weighing it down, leaving it soft, shiny, and more manageable. It also provides heat protection, making it ideal for those who use styling tools. The serum has a pleasant, subtle fragrance that doesn’t linger too long. While it’s a bit pricey, the results—healthier, stronger hair—are worth the investment. Perfect for anyone struggling with dry, brittle hair, it’s a must-have for deep hydration and repair. Highly recommended for damaged hair types.

Using as sub for discontinued Fibre Architect

Used Fibre Architect for years and loved it. Still sad that it’s discontinued by Kerastase. I’m trying this as a substitute for Fibre Architect — and although the styling hold is not as distinct, I will keep using it because it’s almost impossible to find a lightweight styling cream that isn’t stiff or sticky and helps control frizz and flyaways especially around my face. It gives the “piecy” look I love without buildup or stiffness. Not as much “hold” as Fibre Architect but will keep using Serum Therapiste - because I can’t find a perfect replacement for Fibre Architect. (Bring it back please!)

good serum for detangling/strengthening/smoothing hair. It doesn't weigh down hair at all. Give it 10 minutes and it will fully absorb even into fine hair. My hair looks and feels like silk with it.

No Results and Poor Pump Design

Didn't see results. Too expensive for such little product. Also, the pump seems to separate the cream from the gel. It's hard to get product out from the pump. With so many other Keratase products that produce results, this is a pass for me in the future.

Only Heat Protectant I Will Use

[This review was collected as part of a promotion.] I've tried so many different heat protectants from Kerastase, and although I'm certain they each work for a particular hair type, I'm always left with oily-looking, limp hair that's overburdened with product, no matter how little I use. But not with the Sérum Thérapiste. It is exceptionally light yet also keeps split ends and breakage to a minimum. It also lends a lovely sheen to my hair that is unparalleled. And just a pump or two is ample for shoulder-length hair. This is literally the only heat protectant I will use for fine hair.

It did not work for my dry hair

Not helping with the Dryness. I feel like my hair is falling more than usual. It’s dry and not shiny at all. I have used this line of shampoo with a pre-shampoo conditioner and the results were amazing but this time around it’s discontinued so I’m using the shampoo and this product and I don’t see the benefit. I’m wondering why that was discontinued.

Repairs my highlighted fragile hair

I love this stuff! My hair stylist recommended it to me several years ago. I have bleached blonde hair and it was very brittle and fragile from hypothyroidism (which I didn’t know at the time). I only use kerastase products. I use a heat protectant before I blow dry and then I put this on my dry hair before I use a hot tool or just after the blow dry to smooth things out. It is heavier than some other oils so I mostly concentrate it on my ends. It is amazing!

Serum Therapiste Hair Serum

[This review was collected as part of a promotion.] Serum Therapiste is my go to product to bring. Immediate all day softness and smoothness to my hair. This serum has a lightweight feel and pleasant scent. Highly recommend this serum.

Silky and Soft

I love this product! I happened on it at a salon one day looking for something to repair my thin, brittle hair and I've been using it ever since!

Works great for ends

[This review was collected as part of a promotion.] After you damage the ends of your hair with the flat iron, this great to apply to repair as well as prevent. Smells great!

Obsessed!

[This review was collected as part of a promotion.] I love this dual product so much! I use it before blow drying and it really helps protect my hair and make it shiny. I wish it was triple the size though bc I go through it so quickly

ZERO results even though it makes big promises for

Like putting nothing in your hair. Did not mitigate dryness, make hair softer or anything and I don’t even heat treat my hair. Also, I like the scent but it is Over Powering.

Great product!

[This review was collected as part of a promotion.] I love using this in my hair after waking up in the morning! I wear my hair wrapped in a cap all day, and I take it out at night and it is soft and refreshed. Love the smell!

Smooth and Silky

[This review was collected as part of a promotion.] Perhaps my favorite Kerastase product. It calms the frizz and flyaways of my hair. And smells nice.

Game changing

[This review was collected as part of a promotion.] i didn’t think it was doing much at first, but then it started to kick in and really nourished my hair and repaired it due to aging process, thinning, color processed. I’m very pleased!

Définitivement le meilleur

Parfum incomparable. S'il n'était pas efficace je l'achèterais uniquement pour son odeur. Le seul véritable démêlant chez Kerastase. Mon produit préféré

A Little Goes a Long Way

The smell is great and the texture is on the medium heavier side depending on how much you use. I have lower porosity hair - what’s worked best for my hair type and is 1 pump for my just below the shoulder hair and 2 when my hair goes below my bust.
