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 can't believe this is a Kérastase product. I used it as usual. Hair looks shiny and amazing, as usual. But the next day, hair looks and feels like straw- not usual. I'm returning this (Birchbox has a generous and fair return policy). I'm so disappointed.1
I loved the effect and the smell of the this product. It was light and made my hair feel great.3
this is 1 of my most favorite products for my hair of all time. make ur hair super shiny after you flat iron or curling. even more awesome when u put a little in ur hair after showering5
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
