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.
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.4
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.5
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!5
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.5
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.5
Smells amazing. lightweight, non greasy...keeps hair smooth and the ends looking freshly cut. Will definitely repurchase and try more Keratase products!5
This serum does wonders for damaged hair. Paired with the mask, I can really tell a difference in my hair. I highlight my hair and as a result, my hair is broken and full of split ends. I don't know whats in this product to seal those split ends, but if you have damaged hair I highly recommend! It smells amazing to boot!5
This product really seems to diffuse the look of split ends. I only wish that the bottle was larger. The smell is wonderful, as well.5
I cannot rave enough about Fibre Architecte! My hairstylist introduced me to it, and I am addicted. It makes my hair feel smoother and softer than it ever has, and tames flyaways and frizz on humid days. It smells great, and it truly makes my hair feel like I just had it done at the salon. It's expensive, but totally worth the price. A little goes a long way. My highest and most enthusiastic recommendation!5
I have been using this for a few years now and keep it in constant supply so I don't find myself at the bottom of the bottle without new stock on hand. It is essential for my hair which is wavy and frizz prone in humid weather. It smooths our my locks and helps protect it from the heating elements I use on a daily basis. It's a little mnore expensive than other serums but well worth it. You don't need much (I use 2-3 pumps and I have medium to long hair) and that lasts me about 1 1/2 to 2 months. Great investment for your hair!5
