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.

must have!

This is the best for overprocessed hair. You will notice a huge difference the first time you use it! Worth every penny!

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.

Love the product, but tiny size
Purchased

I love the product, I feel like it gives my long hair the extra tlc it needs, leaving it soft and smooth. I am a Kerastase devotee, and am used to their styling products being the typical 4.2 ounces. I wish I had paid attention to the size when I ordered. This bottle is tiny and its expensive!!!

Actually Works

I rarely find a hair product that makes a noticeable difference in the health of my hair, but because I color my hair and often style it with hot tools, I am always hoping to find something that helps my hair. I just finished my first bottle of this product, and I have gotten comments that my hair looks healthier (and it feels healthier too!)

Great but not enough product!
Purchased

I'm so glad that I used my bonus points to purchase this - I was shocked by how fast it went! This product smells great and seems to have made my hair healthier (I had a nearly fatal illness and my hair started falling out. I didn't start using this until it started growing back and seems to have kept it shiny and thick), but my hair is really short now, so I didn't over use it and it was gone in about a month!

I wish I could give this a higher rating, but the small size was really too much, and makes this product way too expensive.

Love
Purchased

I love this stuff. My hair has been color treated. It is then dry and brittle. After using this stuff once my hair is soft and smooth and silky can't even tell that I color my hair. I even need this stuff on my daughter and her hair is really thick coarse and curly. This stuff has made her hair soft, smooth and silky.

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.

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.
