Resurrection hair serum fiber renewing hair care for all hair types. The oil and cream texture instantly repairs, reinforces and resurfaces hair fiber. The hair is deeply repaired as its core. The hair fiber regains its strength and elasticity. Hair is toned and revitalized. High heat protection, up to 450F. 76% split ends reduction.

A soothing, calming hair serum has a light texture like drops of water, yet it is highly concentrated with nutrients and active ingredients. Easily absorbed and infinitely beneficial, a serum is skin care for a sensitive, itchy scalp.

  • SP94, powerful, gluco-peptide that enhances hair fiber’s resilience, structure & strength to activate KAPs synthesis.  
  • 6 Amino Acids, each attaches itself to damaged areas of the hair to compensate for the loss of mass.
  • 1 Wheat Protein Derivative, strong affinity with the hair fiber, restores uniformity and smoothness.
  • Ressurection Sap: Sourced from the Myrothamnus Flabellifolia plant - known for its ability to come back to life after 10 years near death - helps preserve the structure of the fiber.

Rated 4 out of 5 by from Smell is amazing This product wasn’t oily and didn’t weigh down my hair. It gave a nice shine to my hair and smoothed ends. Not sure it helped repair it but I love the smell of this serum. I would buy again.

Rated 5 out of 5 by from Holy Grail I have been using Kerastase products for years and I’ve always mixed & matched shampoos, conditioners, leave ins & serums from Kerastase lines & have been very satisfied compared to all other brands. Recently within the last 6 months I decided to try the resistance pre shampoo conditioner because I had a full bottle of the resistance shampoo, the resistance mask, & the resistance Heat protectant (which have helped tremendously with breakage) Then I came across a bottle of this serum in my cabinet that I forgot about, used it, and my hair has been transformed. I believe this product used in conjunction with the rest of the resistance line is what took my hair to over the top amazing, ultra soft & ultra manageable with min fly aways. Game changer & Holy Grail product. For reference I’m bleached platinum long blonde. Also I can’t wait to get my hands on the new line for blonds. Thank you Kerastase for your part in the fun I’m having taking care of my hair!!!

Rated 2 out of 5 by from Wanted to love it but nope I used fibre architect and loved it. Then they discontinued it. I'm just so unhappy with this. Not even close in quality! First bottle was bought online and the creme side stopped pumping two plus weeks before the oil side. I know there is still some of both in the bottle but it's not accessible. Second bottle was a gift purchased by my husband in the salon...he didn't know I didn't like it...but it was a gift so I figured I'd use it. The cream half doesn't exist in this bottle. And yes, before you ask, this is a salon that is a kerasrase salon. The reps are there all the time. Used it twice oil coming out of both sides. It doesn't smooth like fibre architect. Benefits last barely a couple of hours when fibre architect lasted days , and half of what my husband paid for is missing. Issue with two out of two bottles! Never had a problem with the fibre architect (or any kerasrase product), and I got compliments daily when using it. The compliments have all but stopped since using this product, and I haven't had a working bottle. Bring back the good stuff!

Rated 5 out of 5 by from Highly recommend! My stylist started using this product on me and I loved how it protected my hair while drying, and how it didn’t weigh it down. My hair always looks smooth and shiny after using it and taking the time to dry my hair with my styling brush. Very happy with this product.

Rated 5 out of 5 by from LOVE! A friend got this for me last Christmas, 2017 because my hair was so damaged from dying my hair so much. I love love this serum! Last Christmas my hair felt brittle, dry and lots of split ends. Now it’s so healthy. Even my colorist said my hair got so much better. It smells so good. I have thick Asian hair & you only need one pump!

Rated 1 out of 5 by from Doesn’t compare.... Thought I’d try this after they discontinued fibre architect. This does not even remotely compare. PLEASE BRING BACK FIBRE ARCHITECT!!! It was the only amazing product ever!! It kept my hair frizz free and straight in the most humid weather and had three day style memory. Time to find a good product elsewhere I guess.

Rated 5 out of 5 by from Amazing! Sounds strange but I feel joy as soon as I put this product in my wet hair. It smells amazing! My husband keeps telling me how great my hair smells too. It makes my hair feel like silk and I swear after a month of using this product my hair not only looks healthier, shinier, but it feels silky and stronger than it has.
