Ever since we watched the first season of “Gossip Girl,” we’ve been huge fans of Blake Lively’s flowing waves. So we were excited to learn that the blonde actress was the inspiration behind Kérastase’s new serum. Specially designed for long hair, the leave-in treatment adds a high-definition shine while sealing each cuticle (bye bye, split ends). Plus, the light, gorgeously scented formula won’t weigh down your strands.
I use a lot of hair serums or leave ins but this is certainly the best. The smell is divine, and the shine from just one use is kind of unbelievable. Just a couple of drops does the trick and I even notice my husband likes to smell my hair more which is hilarious but welcome.5
This beauty product is a part of my every day routine. The serum leaves my hair feeling weightless and smooth. I've also noticed a difference in the number of split ends in getting. My hair has definitely improved since using this product.5
I went through a rough hair period and this stuff will make your hair look healthier than. It is. It gives it shine, smells great and it seems to seal flyaways and hide dad ends.3
Was hoping this lived up to the price and it did! I have long straight fine hair and I used two pumps and it didn't weigh my hair down at all. It was super soft and shiny. So glad I bit the bullet and bought it.5
This stuff was great. Just makes hair look better - never made it look greasy. As a bonus, it also left my hair feeling very uncharacteristically soft.5
i bought it based on the rave reviews and the super shine this gives. First, I have grown to LOVE LOVE Kerastase (Architect) line and when I use Fibre Architet, the shine it gave with a small pump is amazing. I bought this because there is more in the bottle (1.7 oz) but the shine factor is not as good. The smell is a strong alcohol smell with a hint of flowers and I don't see that it does anything special to my hair (in terms of health). I would stick to the green line next time or use Gold Lust oil which to me is the best at shine factor (and amount of product). Not their best from K.3
I bought this without trying a sample based on some research I did, looking for a product that would help make my long hair more silky smooth and shiny. I blow dry my hair a lot and so it can be really dry. This product works great to give me nice shine and smoothness. I have fine hair and this product doesn't weigh it down - and smells so good. I love the scent - it's a light, clean smell that reminds me of a floral shampoo. The size (1.7oz.) is also really good for me for traveling. I take it on all of my trips. Yes, it's a small bottle, but even with long hair you don't need a lot of it. One pump, rub in your hands and put through your ends. It's working better than anything else I've tried. It's now become one of my favorite hair products. I'll certainly be ordering more!5
I can't live without this serum. I have long, slightly wavy hair, with a ton of fly aways. I always thought my hair was soft prior to using this product but after being introduced to this stuff, my hair world has completely changed! It keeps all of my baby fly aways down making it look super sleek, smooth, and shiny (the shine that you see in commercials). My hair has never been so soft! 1-2 pumps won't leave your hair feeling greasy or weighed down but will leave you with gorgeous bouncy hair.5
I love anything that makes the hair silky and it smells great and this did both of those I apply while hair is still wet and I love the smell of this5
This product works great. My hair was shiny but not oily or greasy. I also really liked the smell. I've tried other products but my hair is always greasy or oily after. I will definitely be buying this!4
