I'm a month into trying this hair serum & as usual with all kerastase products I am pleased with my results! It smells delicious & it makes my hair just feel good! I have fine hair and am always looking for a new product to try to help aid in healthy hair. I look forward to seeing the final results once I finish off my bottle! You get a lot of bang for your buck with this one and it will last me a long time!

I was a hair shredder I feel like I have decreased in the amount of hair I loose in the shower, and my hair does feel healthy I do not use much at my scalp because it will give you greasy roots and let's be honest no one wants that, while I have been happy with it. I'd not say it's a product I'd jump on going out to buy again

Although I truly love just about everything @kerastase, I didn’t find benefit with the use of this product  it’s lightweight, smells great and doesn’t make hair oily but I didn’t see any improvement that would lead to a longer hair growth

I’ve always had very long and voluminous healthy shiny hair. This product made my hair fall. In three weeks of using it my hair has become literally a bit less than half the volume it used to be. I haven’t used it now in 10 days. The process of shedding is starting to diminish. Just be careful it might not be the right one for you.

My hair is doing very well. It helps me keep it hydrated. During these months I have noticed an increase in volume and growth. It has a rich aroma and is very easy to apply. I recommend it, it has helped me a lot.

I love all things Kerastase and hadn't tried this before. My friend Nikki swears by it and I used it 3 times this week. I can see a huge difference in my scalp and also in the shine of my hair. I would absolutely recommend this to a friend.

The thing I love the most about this is the scent: It makes my hair smell like a million bucks. It's a more-than-decent protectant when I use it before ironing my hair, and helps control the frizzies too when I use it sans heat. Bit expensive, but I'm picking Yes on repurchasing it for now, until I can find a cheaper serum that works as well and smells just as fabulous.
