Kérastase Résistance Fibre Architecte - Serum for Damaged Hair

Apologies to Gehry, Libeskind, and all the other starchitects: Kerastase is giving you a run for your money—at least when it comes to jawdropping hair feats. The brand’s dual-phase serum transforms damaged hair by repairing its actual foundations—the fibers in each individual strand. Once those are fortified and healthy, the serum adds ceramides for smoothness and gloss. You’ll have a gorgeous, award-worthy coif.

Wonderful but expensive

I'm not even sure I used this correctly but it worked wonders as a blowout cream. My hair was so smooth and luxurious. I would love to purchase it but it's a bit pricey.

A MUST HAVE for over processed hair; Leaves your hair smooth and perfect!

I swear by this stuff. My outer layers of hair have been bleached and processed, so they are dry as straw- meanwhile the underside of my hair is perfect and smooth. This presents a problem! How do I smooth my outer hair without weighing it down? Taaa daaa! WIth this stuff!
After I wash my hair, I take a dime's worth and rub my hands together, smoothing down my worst hair areas. It works so well that you don't need too much or else your hair will get flat. Afterwards my hair is smooth as silk, as if it had never been processed. Wanna know a secret? There is a L'oreal version of this and its the exact same thing- very hard to find in drugstores but it exists. But when I have the money, this is a must have.

Very good

My hairstylist recommended this line to me. Specifically this serum because he said it nourishes your hair from the inside out. Well, I don't think that is true at all, specially since I finally cut 2-3 inches off my hair and it's finally really healthy. This serum smells very good, a little goes a long way and I really like the shine it gives. Still, not spectacular, and i'm bothered that the price is 40 for 1 ounce bottle. Probably won't repurchase. The whole green line is very good though.

I heat style my hair almost every day and this product helps to control my split ends. It's great serum and addition to my hair routine.

love at first pump!
Purchased

I have been wanting to try this for quite a while and I am so glad I did. I have used it a few times now and I am completely in love. I have wavy, blonde color treated hair and have been experiencing bad breakage and brittleness lately. This leaves my hair feeling so soft, shiny and my strands look healthier overall. I am hoping with continued use of this and the rest of this line it will stop the breakage I experienced. And it smells delicious!

MUST HAVE for heat styling
Purchased

This is the best product I have found in 10 years of heat styling my hair. I particularly focus on ends and it leaves my hair shiny and smelling great.

This serum paired with the conditioning treatment has worked wonders on my hair. I have long bleach blonde hair and get really bad breakage and split ends, but while using this I can see a difference. My hair feels so smooth and it smells amazing too! I just wish there was more in the bottle since I have to use more for my longer hair.
